Some of the important characteristics of life are:-

Metabolism: It is a major characteristic of life without exception. All living organisms are made of chemicals. These chemicals, small or big, belonging to various classes, sizes, functions, etc., are constantly being made and changed into other biomolecules. These conversions are chemical reactions or metabolic reactions.

The sum total of all the chemical reactions occurring in our body is metabolism.

No non-living object exhibits metabolism here for eg. a lab stool that does not exhibit metabolism and hence is not alive.

Reproduction, is also a characteristic of living organisms but with a few exceptions. No non-living object is capable of reproducing or replicating by itself. Hence again it shows why a lab stool is not alive as it cannot reproduce as a living organism can.

The most complicated feature of all living organisms is the ability to sense their environment and respond to these environmental stimuli which could be physical, chemical, or biological. No nonliving object possesses such qualities.

A stool is non-living as it does not possess any of the characteristics of a living organism.

Characteristics of life are

1.Sensitivity or Response to Stimuli- Living organisms shows response to diverse stimuli like plants shows sensitivity to light, they bend towards the source of light. A stool does not show any kind of response to different stimuli.

2.Reproduction- All the living organisms are capable of reproduction whether sexually or asexually but a stool having no living cells is not capable of reproduction.

3.Growth and Development- Organisms do show growth in their body and their structure but a stool is similar all the time it cannot grow on its own, it can only be modified with human efforts.

4.Energy Processing- All organisms use a source of energy for their metabolic activities. Some use energy from sun like plants and some use chemical energy from different substances to carry out metabolic activities. A Stool cannot perform metabolic activities in it as it has no living cells.

5.Regulatory mechanism- Even the smallest organisms are having complex structures and require multiple regulatory mechanisms to perform functions, respond to stimuli, and do other many things.

Hernce from the above points we can conclude that a stool is nonliving object as it does not show any response to stimuli, has no growth and development, is incapable of reproduction, also need no energy.

Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.

Part of: Wall of small intestine

Latin: small intestinales

Villi are adapted for efficient absorption of sugar molecules as a result of its

finger-like structures , shorter diffusion path and large surface area.

Villi are finger-like structures found in the small intestine which aids the

The life cycle of a cicada is different from the life cycle of a termite.

Cicadas undergo three stages of life as well as Termites undergo three stages of life, for both known as, egg, nymph and adult stages.

The cicadas can be annual and periodical. They have a similar life cycle with some differences. Annual cicadas are found all over the world in several different areas and climates whereas periodical cicadas emerge in thirteen- or seventeen-year cycles.

Termites lay their egg in jelly-like liquid holding them together and one female termite has the capability to lay around 30,000 eggs in a day.

If the concentration of a vitamin in the filtrate exceeds the transport maximum (Tm) of that vitamin, the excess vitamin is excreted in the urine (Option B).

The transport maximum (Tm) is the maximum rate of substance reabsorption that is not exceeded by increasing the concentration of the substance in the tubular fluid. Tm is similar to the maximum capacity of a bottle, which can only hold a certain amount of fluid beyond which, any extra fluid is spilled out.

Therefore, if the concentration of a vitamin in the filtrate exceeds the transport maximum (Tm) of that vitamin, then the excess vitamin cannot be reabsorbed by the renal tubules and is excreted in the urine. Excess vitamins in the body are harmful since the body cannot store water-soluble vitamins. Water-soluble vitamins are rapidly excreted in the urine if they exceed the body's requirements or are in excess in the body. This is why it is important to take vitamins in recommended doses, which can be obtained from a balanced diet.

Thus, the correct option is B.

Darwin thought that rabbits never developed in South America. He concluded that rabbits developed elsewhere and could not reach South America. The correct answer is option d

Darwin's theory of evolution through common descent argues that distinct species originate from a common ancestor and are not scattered globally. Rabbits had no ancestral presence or evolutionary ties to South America. Darwin concluded that rabbits could live in South America despite a lack of food and a heated temperature.

Instead, he suggested that their evolutionary history and geographical limits prevented rabbits from living in South America. Darwin did not suggest that South American rabbits had become guinea pigs and disappeared. He believed that rabbits did not evolve in South America. Genetic and fossil evidence can uncover ancestral relationships and evolutionary routes.

The addictive chemical of Nicotine.

Explanation:

Nicotine, chemically speaking, is a colorless, oily, water-soluble, highly toxic, liquid alkaloid, C10H14N2, found in tobacco and valued as an insecticide.  

Nicotine addiction occurs usually from smoking cigarettes or using other tobacco products. The chemical nicotine activates pleasure centers in the brain, releasing dopamine - see below - (neurotransmitter) and other chemicals that make you feel good. With repetition, pathways are created that connect smoking and the idea of "rewards". Changes take place in the brain that increase the sensitivity in brain receptors. Basically, the more you or someone else smokes, the more your brain believes that you not only want, but need, smoke.

Nicotine can cause a very common disease known as Lung Cancer.

Magnification is the process of visually enlarging an object, not physically increasing its size but only increasing its apparent size.

This idea of magnification can occur in one of two ways: telescopic magnification brings distant items closer, while microscopic magnification makes little objects appear larger (and thus clearer and more defined).

In order to avoid any confusion between the two, we shall here only focus on microscopic magnification and the kinds, formulas, and calculations related to that process alone.

It is vital to highlight that both forms use quite distinct instruments and formulas.
