Animals

Introduction

This poem, “Animals,” is a metaphor for the animals’ inherent innocence. The poet has stated that he wants to remain among the animals since they are significantly more cooperative and uncomplicated than humans. The poet has dug out the dark side of human nature, revealing that people may be more dangerous than animals. So, the poem demonstrates the poet’s compassion towards animals.

Summary of the Poem

The poem Animals suggests that at one point in time, people were just as receptive to the earthy pleasures all around them as animals were, but this has changed. The animals were as content as always, but humans, with their greed, rage, envy, and inability to find joy in anything, had descended to the lowest echelons of society.

They are never content with what they have and constantly make excuses to the World for their faults in an effort to purge themselves of their egocentric goals. Having lost the ability to appreciate even the smallest of life’s pleasures, they have gone mad and developed sleeplessness.

The poet continued by saying that people have forgotten how to sustain themselves because they are caught in the web of a variety of complexities and confusions surrounding them and the negative soul’s pursuit of ever-increasing power and worldly pleasure. Contrarily, animals maintain a constant attitude of gratitude and contentment.

The poet lamented that humans always seem to find something to complain about, whereas animals seem content with their lot in life. They lack an obsession with accumulating material goods. None of the animals is obligated to show respect to members of their own species. All of them have the same happiness and dignity. The poet aspires to take a cue or two from animals, who lack the capacity for deceit and apply those lessons to his own life. Their high moral standards astound the poet.

About the poet

Walt Whitman, an American poet, essayist, and journalist, was born on May 31, 1819, in New York City. Sometimes referred to as the “father of free verse,” Walt Whitman was a pioneering figure in American poetry.

Conclusion

Animals, in Whitman’s view, represent feelings of affection and reverence for people. and they’re happy with their life overall. As a result, they don’t feel the need to acquire a lot of stuff. They don’t have any complaints and treat sadness and happiness equally. While animals continue to be content, humans are so preoccupied with the external world that they neglect the inside factors that contribute to their happiness.

Just like humans, they value their time too much to waste it on arguing over their duties to God. Humans and animals alike exhibit behaviours such as love, tranquilly, self-love, honesty, patience, and empathy, as Whitman pointed out. These traits are crucial for a fulfilling existence.

Textbook Question Answer

1. I think I could turn and live with animals…” What does this line signify?

Ans: The poet wants to turn himself away from the human community  and wants  to be with the “Animals”.as they have turned to a selfless group of living souls. He found “Animals” to be more content and happy for themselves.

 2. Can you mention any three things that Humans do and animals don’t?

Ans: The three things humans do and animals don’t are as follows:

  1. Humans possess a complaining nature about their existence.
  2. Humans always crib about their sins and past deeds for which they sometimes regrets.
  3. Humans try to get rid of their sins by bestowing them upon God as they think God might help them by coming out of the same.

3.Have humans ever kneeled to their ancestors in the past?

Ans: Humans were considered to be dedicated disciples of their followers, elders, saints or priests and followed their principles dedicatedly and obeyed them by kneeling down. This shows that Humans earlier had an innate sense of respect and belongingness towards their elders. Thus poet tried to exhibit that this belongingness is missing in today’s Humans. 

4- What does the word ‘tokens’ signify in the poem that the poet mentioned that he may have dropped long ago?

Ans:– The word “tokens” express the sense of decency that all the animals brace up without lamenting for any worldly attraction around them, whereas Humans have gradually discarded and shredded this priceless value of happiness.

 

Important Extra Questions and Answers

1. Why does the poet have a preference to stay with the animals?

Ans: The poet has a preference to stay with the “Animals as Humans are trapped in the cobwebs of several complicates and confusions around them and the negative soul to get more and more power and earthly pleasure they have forgotten how to sustain. On the other hand, Animals are always content and thankful for what they have.

Ans:-Here the token signifies a “Token of love”.Animals tend to be happy and content with what God has given them and do not hold grudges about any sort of materialistic  and worldly object.

3. What is the major theme of the poem, ‘Animals’?

Ans:According to the poem Animals, both Humans and Animals had an innate happiness and both were happily living ever after but over the time humans became reluctant about the earthly pleasure around them. The animals continued with their same happiness. Hence this differentiation stand out to be the major theme.

4.How are animals better-living souls than humans, according to the poet?

Ans:-In the poet’s point of view, animals are more compassionate than humans and they do not bear any negative qualities as humans do. In their world, all are happy, and glad. They show their relations to the poet, and he accepts them.

Iron Tools and Agriculture in Ancient India

Introduction

The discovery of iron led to a revolution in Indian agriculture. By the end of the Chalcolithic Age, the Indian subcontinent had been using iron for around 2500–3000 years. Now, during this time, the tools made of iron and steel were stronger and more efficient than those made of bronze. Manufacturing iron tools enhanced farming and contributed to a bigger economy.

The creation of iron farming implements greatly facilitated the agricultural process and contributed to a larger increase in farm produce. People were able to adapt to a stable existence at that time through commercial farming (trade between other nations) and subsistence farming, which helped people produce in huge amounts. Iron implements contributed to the prosperity of tiny kingdoms in a similar manner.

Indian Iron History from a Historical Perspective

In India, evidence of iron tools has been found in megalithic (big stone) burial sites. These sites in India comprised modern-day Karnataka and Kerala in the south, extended to some parts of central India and trans-Vindhyas. In many of these sites, the use of iron perhaps started by the end of the Neolithic and during the Chalcolithic age. 

Our Rig Veda and Yajur Veda contain references to the process of obtaining metal from ores. Iron was the third metal mentioned in Rig Vedic hymns, after gold and silver. Iron utilisation saw rapid development around 1400 BCE. Early evidence of iron smelting was thought to have been produced by tribal craftspeople in several places. 

Agriculture and the Iron

Agriculture underwent a turning point with the invention of iron. People have now begun to create powerful, long-lasting, and simple-to-form tools and weapons with this metal. 

This allowed them to create a compact, extremely sharp, and lightweight instrument that was challenging to craft out of stone or copper. Sickles, axes, spades, and plough shares are a few examples of significant tools. They could now plough difficult land thanks to these.

As agricultural output increased, people started to stay put in one location for longer periods of time, as opposed to moving around in search of food and water. The size of kingdoms also grew as a result. 

The king was now in need of money or taxes from the population to maintain his country. Farmers became the principal taxpayers because agriculture was one of the kingdom’s most productive industries. The monarchs used to encourage farmers by making arrangements for canals, wells, and tanks to boost farm output to increase the revenue from this field.

Iron Tools

The use of iron tools fundamentally altered human life. A new type of permanent community emerged with the large-scale production of tools. The provision of military equipment like iron swords and other weapons that were utilised by armies and soldiers for fighting wars and conflicts, not only changed agriculture but also established the groundwork for large kingdoms and empires. Since the idea of communities had begun to take hold, individuals had started to build their spheres of influence.

People, now, began establishing ties with other nations as well. The development of agriculture and the subsequent creation of surplus grain opened the door for thriving trades. Tools were traded for grain, which resulted in the growth of trade customs. Over time, as trade increased, coins started to be used in transactions. Numerous Roman coins have been discovered by archaeologists in India.

Summary

The discovery of iron altered the course of history. Its discovery was unexpected, but its expansion took centuries. The tribals of India carried the traditions from antiquity to the modern era. When the famous Damascus sword was being prepared with indigenous steel-making technology, India was the workshop of the entire world. The invention of the iron in some ways created the groundwork for a civilization that was more civilised. However, as with any historical event, there were ups and downs in India’s iron history due to a variety of internal and external factors.

Frequently Asked Questions (FAQs)

1.How did Early Humans Discover Iron and use it for Tools?
Ans: Humans had figured out how to extract iron from rocks and turn them into implements made of iron. Iron was first discovered in rocks, or iron ore, which was melted at extremely high temperatures. The iron was heated and hammered while in contact with charcoal, resulting in the iron being stronger and more durable.

2.What Effects did the Iron Age have on Human Life?
Ans: The development of iron tools aided in making farming easier and more efficient. Farmers could plough tougher soil, allowing them to harvest new crops and free up time for more leisure activities. Throughout the Iron Age, new crop and livestock varieties were introduced at various times.

3. How did Early People’s lives Alter between the Bronze and Iron Ages?
Ans: Around 1200 BCE was the start of the Bronze Age. Tools from this era were constructed of bronze. Iron, which was more durable and powerful than bronze and so brought about the Iron Age, soon took its place.

A Study on Various Modes of Excretion

Introduction

Every living thing engages in metabolic processes that produce compounds that, if allowed to build up in the body, could be poisonous. These materials are regarded as excretory wastes. Depending on several internal or external conditions, each organism uses a different technique to remove these wastes. We shall learn more about these excretory processes in this article, including the types of excretory products that each one eliminates.

Excretion and Excretory Wastes

The process of eliminating harmful or non-toxic wastes from the body is known as excretion. Each organism produces various excretory products. For instance, the primary excretory substance in fish is ammonia, whereas the primary excretory substance in humans is urea. These wastes are removed from the body via excretory organs.  Every living organism has a unique excretory system in its body.

For more help, you can refer to Science Class 7 Lesson No 11. Check out the video Lesson for a better understanding.

Methods of Excretion

Nitrogenous wastes produced during protein metabolism are the main excretory products produced by an organism. The conversion of the main nitrogenous waste ammonia results in the final excretory products of an organism. The final excretory products that are eliminated using a particular procedure are used to categorize the various excretion processes.

Ammoniotelic: Ammonia is released as a waste product during ammoniotelic. Because ammonia removal needs a significant amount of water, aquatic creatures like fish, poriferans, protozoans, etc. exhibit ammoniotelic. These creatures are referred to as ammoniotelic organisms.

Ureotelism: Ureotelism is the process of discharging urea as the final excretory waste. In terrestrial species like humans, it is common. A moderate amount of water is necessary for the body to remove urea from it. Ammonia is changed into urea in the livers of ureotelic organisms.

Uricotelism: Uricotelism is the elimination of uric acid, which is the ultimate excretory product. Because uric acid does not dissolve in water, the waste produced by uricotelic organisms is expelled as paste or pellets. Animals, including birds, reptiles, and some insects, exhibit uricotelism.

Guanotelism: Guanine is released as the body’s ultimate excretory product during Guanotelism. Guanine cannot be removed with water since it is an insoluble substance. Guanotelism has been observed in various spider species, as well as some types of earthworms and reptiles.

Aminotelism: The elimination of final waste products in the form of amino acids is known as aminonotelism. Mollusks and echinoderms both use this technique of excretion.

Urinary excretion

Excretion in Humans

The human body produces urea, uric acid, ammonia, and carbon dioxide as excretory products. Three of these are nitrogenous metabolic wastes that are eliminated in the urine or sweat, but carbon dioxide is a non-nitrogenous metabolic waste that is eliminated in the expired air. Let’s talk in detail about these excretory processes in humans.

Urination: The kidneys and other related organs perform several procedures to remove nitrogenous waste from the body. Urine, the last byproduct of this process, is excreted from the body by micturition. Urine formation happens in three stages. The nephron, which is the kidneys’ functional unit, performs each of these processes.

Glomerular filtration: The renal capsule, a nephron-like structure containing a cluster of blood capillaries, is where the first stage of urine production takes place. In this step, the blood is ultrafiltered, and the majority of the plasma as well as a few other molecules, including wastes, are taken out of it in the form of glomerular filtrate. This glomerular filtrate travels into the nephron’s long renal tubule, where it is absorbable.

Tubular reabsorption: The nephron is a structure that filters blood into a fluid called filtrate, much of which is then reabsorbed into the body. Resorption is a carefully regulated process that is modified to keep blood volume, pressure, plasma osmolarity, and pH in a stable state. Through the peritubular capillaries, reabsorbed liquids, ions, and molecules are restored to the bloodstream instead of being eliminated as urine.

Secretion: In this stage, chemicals like creatinine, hydrogen ions, and drugs are released from the renal tubule walls and transferred to the urine. Each nephron produces urine, which the collecting duct gathers and then excretes through the ureters into the urinary bladder. The urethra is the passageway through which urine exits the body once the urinary bladder has become bloated.

Expiration: Humans expel carbon dioxide through breathing, which is the metabolic waste product created during respiration. During this phase of breathing, the air is expelled through the nostrils.

Sweating: Sweating eliminates extra water, salt, and some urea from the body. This is brought on by the sweat glands in the skin producing sweat.

Examples of Excretion

The human body’s different organs that are responsible for excretion include the kidneys, lungs, large intestine, liver, and skin. A few examples of excretion include the release of bile by the liver, which travels to the small intestine before exiting the body via the large intestine. The large intestine is one organ in the body that excretes solid wastes.

Importance of Excretion in Living Organisms

  • The removal of wastes from the body is crucial because if they are left there for an extended period, they can seriously harm the organ systems. 
  • For instance, if urea builds up in the body, it can be extremely poisonous and cause uremia. 
  • Too much carbon dioxide in the blood will cause carboxyhemoglobin to form and cause the blood to become acidic, which will reduce its ability to carry oxygen. 
  • If faecal matter forms in the alimentary canal after the conclusion of absorption is not cleared, it could lead to the accumulation of hazardous bacteria and fermentation products, which could injure or impair the gut’s normal function.

Summary

The process of eliminating harmful or non-toxic wastes from the body is known as excretion. The final excretory products that are eliminated using a particular procedure are used to categorize the various excretion processes. The body produces urea, uric acid, ammonia, and carbon dioxide as excretory products. The human body’s different organs that are responsible for excretion include the kidneys, lungs, large intestine, liver, and skin. The removal of wastes from the body is crucial because if they are left there for an extended period, they can seriously harm the organ systems. 

Frequently Asked Questions  

1. What is Renal Ultrafiltration? When does it Occur?
Ans. One of the kidney processes that dialysis treatment substitutes are the process of ultrafiltration, which involves draining fluid from a patient. When a driving pressure causes fluid to cross a semipermeable barrier, ultrafiltration occurs.

2. Nephrons are made up of different Parts, what are They?
Ans. Each nephron is made up of a proximal tubule, which is a convoluted and straight component, a renal corpuscle (glomerulus inside Bowman’s capsule), an intermediate tubule, a connecting tubule, a distal convoluted tubule, an outer, cortical, and inner medullary collecting ducts, among other structures.

3. Give an example of a Disease that can Develop as a Result of the Buildup of Nitrogenous Waste in the Body.
Ans. A medical disease known as uremia is brought on by the harmful consequences of unusually high levels of nitrogenous chemicals in the blood as a result of the kidneys’ inability to eliminate waste products through the urine.

4. What Happens if Excess Carbon Dioxide Accumulates in the Blood?
Ans. Too much carbon dioxide in the blood will cause carboxyhemoglobin to form and cause the blood to become acidic, which will reduce its ability to carry oxygen.
