Answer- No

No because your skin color doesn’t only how to do with genes, it also has to do with the genes of grandparents great grandparents etc. in addition to the environment, for example if you live in the tropics, you would have more melanin to help not get burned by the sun because of the adaption of constant sunlight.

8 Natural selection produces changes most quickly in

Olegator [25]

Answer:

Natural selection produces changes most quickly in species with short reproductive cycles.

Explanation:

Natural selection implies a process of changes in the genome of species, induced by their environmental conditions, which allow them to survive. The processes of natural selection usually manifest themselves after long periods of time and are synonymous with adaptive evolution.

Since natural selection depends on the changes observable in successive generations within a species, in organisms with short reproductive cycles the changes promoted by natural selection could be observed most quickly.

Choose all that apply. Which of the following is true in a comparison of your skin cells to your kidney cells?

ruslelena [56]

Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".

The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.

What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).
