Evolution of a species could occur as a result of changes in the
victus00 [196]

Options for the question have not been provided. They are as follows:

(1) DNA in muscle cells

(2) base sequences in liver cells

(3) genes in an egg cell

(4) number of chromosomes in a fetal bone cell

Answer:

(3) genes in an egg cell

Explanation:

Evolution is the change in characteristics of a species which it develops over the time. These changes can be a result of natural selection, genetic drift, founder effect etc. They are passed from one generation to another hence the alleles for them get fixed in the population.

For evolution to occur, change should take place in germ cells. Germ cells are the one which fuse to form the organisms of next generation. If there is a change in their genes, it would also appear in next generation, unlike changes in genes of somatic cells. Since egg cell is a germ cell it is the correct answer.

AnnyKZ [126]

Answer:

The correct answer would be - functions.

Explanation:

The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.

In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.
