How does the DNA found in your eye cells compared to the DNA found in your skin cells?

It sounds like you are already well aware of the fact that every cell in our body has the same set of genes. This is because all of the cells in our bodies start from a single fertilized egg. That first cell divided over and over again until a new baby was made. In the end, we all are made up of trillions of cells with nearly identical genes*. And yet, all cells are obviously not the same. It is easy to see that the cells in our heart, for instance, work very differently from the cells in our eyes. The same is true for our skin and our liver cells. Or our brain and muscle cells. Or any of the other 300 or so different cell types. These cells are different because they use the same set of genes differently. So even though each of our cells has the same 20,000 or so genes, each cell can select which ones it wants to "turn on" and which ones it wants to keep "turned off". It might help to think about our set of genes as a cookbook and each of our cell types as a different cook. So the breakfast cook focuses only on breakfast recipes and the lunch chef only on lunch ones. Just like our heart cells focus on heart genes and our eye cells on eye genes. Of course our genes aren't recipes for blueberry pancakes or minestrone soup. Instead, they are actually recipes for proteins.

Explanation:

answer: the answer is d.

explanation: this is because when you exercise you make your muscle produce a certain liquid, that does not evaporate it.   also when you exercise you do not reduce muscle fiber.   and it does not really control your twitch that much.
