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.

Polypeptides produce?

Masja [62]

Polypeptides help make up proteins by bonding numerous amino acids together. Proteins are created by the bonding of two or more polypeptides, which are then folded into a specific shape for a particular protein.

15. Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 30 percent solute solu

Vaselesa [24]

Answer:

Smaller

Explanation:

The human blood cell has a smaller percentage of solute concentration than the solution it was placed into. This means that the cell is hypotonic in comparison to the solution, and the solution is hypertonic compared to the cell. When a cell is placed in a hypertonic solution it undergoes crenation, meaning it shrivels up. Water moves from the lower solute concentration to the higher solute concentration. The water inside the cell moves outside to the hypertonic solution. This causes the cell to become smaller.
