The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.
Answer:
option B) intracellular receptors are present only in target cells.
Explanation:
The cell membrane or plasma membrane is composed of phospholipids and thus hydrophobic in nature, this allows the lipid soluble signaling molecules to cross the membrane. The cell membrane of all cells consist of phospholipids thus hydrophobicity of each cell membrane allows lipid soluble signaling molecules to pass through the plasma membrane. The testosterone cross the membranes of all cells but affect only target cells because of intracellular recepters that are located in target cell. The binding of signaling molecules to recepter generates a response. Thus, option B is correct.
B. complementary to the template strand of DNA on which it forms.
Answer: Scientific Findings are communicated by putting it in a Scientific Journal, or Writing a Lab Report
Explanation:
Answer:
This process is called transcription
Explanation:
This is where DNA is copied to make a RNA molecule.
