<h2>Answer and Explanation</h2>

DNA is called deoxyribonucleic acid. DNA is different in all plants and animals but according to the chemical structure, it is the same as double helix strand that is separated from each other. In a person body, all the DNA are the same but they are different if the cells, tissues, and organs are different. There are some mammals have slightly similar DNA that is humans have 99.6% same DNA as the chimpanzees.

Where are fats, carbohydrates, and proteins broken down into particles small enough to be absorbed into the body?

siniylev [52]

Answer:

Duodenum (option 3)

Explanation:

Digestion of carbohydrates, proteins, and fats continues in the small intestine. Starch and glycogen are broken down into maltose by small intestine enzymes. Proteases are enzymes secreted by the pancreas that continue the breakdown of protein into small peptide fragments and amino acids.

The duodenum is the first section of the small intestine and is the shortest part of the small intestine. It is where most chemical digestion using enzymes takes place

Q - Describe the Mitoses with the help of diagram. write its different phares and explain them.

bonufazy [111]

Answer:

Mitosis is a type of cell division in which single haploid cell (n) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent.

Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.

1.Prophase:-

It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared.

ii. Metaphase:-

Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibers. Spindle fibers are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congressional and plate formed is called metaphasic plate.

iii. Anaphase:-

The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibers. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.

iv. Telophase:- The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear.

Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinetic and is also known as reorganization phase.

It is followed by cytokines or division of cytoplasm.

STALIN [3.7K]

It appears that the same lifestyle factors that contribute to the development of Cerebrovascular disease also increase the risk for vascular dementia. Vascular dementia describes the problems with reasoning, planning, judgement, memory and other thought processes caused by brain damage from impaired blood flow in the brain.

According to the article, why might Indians rationally choose not to eat cow even during times of starvation?

ludmilkaskok [199]

Answer:

Many Indians believe in Hinduism, which preaches that cows are sacred. They might choose not to eat cow even during times of starvation because they are afraid of the consequences that come in the afterlife. Because cows are sacred, Indians believe that eating them might incur a net negative benefit when considering the afterlife.

Explanation:

No article was provided and I don't particularly know much about the subject so this is my best guess. Please adapt this answer accordingly.
