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.

Which factor does not play a role in runoff
vladimir1956 [14]
<span>Infiltration is the process by which rainwater becomes groundwater. In the water cycle, which involves primarily; evaporation, condensation and precipitation. Henceforth, after precipitation comes infiltration in the land areas leaving the rainwater aggregated in a single location which accumulates over time. Then this process is followed by runoff and subsurface flow by which water flows through other bodies of water, either in river, sea or ocean, even lake. Other rainwaters that has segregated and wasn’t able to transport itself stays in the process of infiltration, thus groundwater.<span>

Thus, solar radiation doesn't play a role in runoff or infiltration.
