Katyanochek1 [597]

Answer:

The correct answer is - 2n = 41 chromosomes.

Explanation:

It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -

Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).

Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)

19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.

Gnoma [55]

Answer:

Selection may be defined as the process of selecting the more favorable species than the less favored one and can adapt in the environment. The selection increase the chances of survival of the organism.

The genetic variation hidden means the variation is not visible in the population and present in the form of heterozygotes in the population. This genetic variation can be expressed by the recombination of the heterozygotes in the population.

The stomach,small intestine, esophagus or liver secretes special enzymes that help the stomach digest fats.

scZoUnD [109]

Explanation:

<u>The stomach </u>

Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food with the use of enzymes. The stomach secretes the enzyme, gastric lipase to digest fats.

Further Explanation:

Food is chemically and mechanically broken down into smaller particles. In the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components. Phospholipids, bile acids, bilirubin, and cholesterol are combined into bile in the liver, which when secreted into the duodenum of the small intestine; this comes from its storage site, the gall bladder, and functions as an emulsifier or as a detergent.

These hold the fats and water together and increase the surface area of lipids, which can be further digested by enzymes so the nutrients are further broken down for absorption into the bloodstream.
