Answer:Dehydration
Explanation:
Dark urine is usually indicative of dehydration; but there could be more reasons responsible for it. Ideally, when you eat or drink something, it goes through your digestive tract, circulatory system and then to your kidney. Kidneys are where everything is filtered and urine is produced. Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.
Hi!
The correct option is B. Which genes are active.
Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.
But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.
Hope this helps!
