Rabbit ear size tends to decrease as latitude increases. this is an example of a cline
.
A cline can be described as a change of the biological trait of a species across its geographical range. A cline can be genetic for example, change in the allele frequency, or phenotypic (change in body size). The change can be shown as continuous gradation, or it can be more abrupt from one geographic region to the next.
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.
Answer:
This is the basis for Chargaff's rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds
