Answer:

A) Chromosomes are made of DNA

C) Alleles are the different forms of a gene that can exist

D) Chromosomes contain genes that control the inheritance of traits.

Explanation:

Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene  (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.

Akimi4 [234]

Answer:

<u>Option:</u>Symbiosis in which both organisms benefit ecological niche.

Explanation:

  • <u>Symbiotic association between any living organism:</u>

The symbiotic association is the connection between any organisms, which are either benefited by each other or the relationship can be very negative for the either one, or it may be neutral in nature for both the organisms living inside a symbiotic relationship.

The symbiotic association between the different organisms are of four different natures or levels,which are as follows:

  1. <u>Mutualism:</u> Inside the relationship or connection between any number of organisms in which there is mutual benefit for both the organisms, is called as the mutualism. For example, the insecticides living in the plants roots or any part of its body.
  2. <u>Parasitism:</u>Such a symbiotic relationship is which between any two living organism either one of them is benefited while the other one is harmed by its effect. For example, the tape worms in the living body.
  3. <u>Predation:</u> It is more simple to understand as the prey is hunted down and killed in order to fulfill the needs of the predator.For example the lion and the impala.
  4. <u>Commensalism: </u>The type of association between the living organism in which one of the organism is benefited, while other is neither benefited nor harmed. For example the marine life on the back of the crab's body.

Water is essential for survival. It is important to understand the factors that affect water balance and the best sources to hel
Ludmilka [50]

Answer:

2-Water helps maintain body temperature.

3-Diuretics like alcohol and some medications can cause the body to lose water.

Explanation:

Dehydration occurs when the amount of what loss is more than the amount taken. And we lose water in many ways therefore taking water on a regular basis is important to replace the fluids lost and keep the body functioning.

Water Maintains the Body Temperature

During high temperature, the body cools itself naturally by sweating and by sweating a large amount of water is lost. So when enough water is not taken, there will be less production of sweating thereby causing the body's temperature to rise.

Alcohol Causes Water Loss

Taking excess alcohol can result to dehydration because the hormone called anti-diuretic (while alcohol is diuretic) is used to reabsorb water by the body and alcohol in the body depletes the production of this hormone. The body loses more water than normal with a reduced amount of anti-diuretic in the body. Excessive intake of alcohol can also cause vomiting, which depletes the body of fluids and can cause further dehydration.
