The table below provides the number of chromosomes found in the body cells of various types of organisms.

diploid chromosome number

fruit fly
8

human
46

goldfish
94

which of the following is the best explanation for why the chromosome numbers above are all even?

a.) animal cells always have an even number of chromosomes, and plant cells always have an odd number of chromosomes.
b.) the number of chromosomes present in a diploid cell doubles for each generation because there are two parent

Answer;

B.) The number of chromosomes present in a diploid cell doubles for each generation because there are two parent.

Explanation;

-A diploid cell is a cell that contains two sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be one homologous chromosome set.

-A single chromosome set consists of two chromosomes, one of which is donated from the mother and the other from the father. Humans have 23 sets of homologous chromosomes (which makes  46 chromosomes).

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
