Answer:
E
Explanation:
In DNA molecule, the number of guanine bases will always be equal to the number of cytosine bases. Genuine make a triple hydrogen bond with cytosine. That's why the number of guanine bases is equal to cytosine bases.
Answer:
(B) Interstitial fluid
Explanation:
The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.
