Answer:
the function of cell membrane is to provides protection for a cell.
The answer is splitting of water molecules. This happens during the light stage of photosynthesis where light energy from the sun is absorbed by chlorophyll is used to split water molecules into hydrogen ions and oxygen. This process is called photolysis. The hydrogen ions joins the dark stage or the light independent stage, while oxygen gas is either released to the atmosphere or used for cellular respiration.
So, this hormone is a non-steroid hormone. Steroid hormones are fat soluble and can pass directly into the cell to affect the nucleus.
Non-steroid hormones bind to the receptor and trigger a chemical change within the cell without ever entering the cell, or the nucleus.
The answer is: It will not enter the nucleus
The answer should be C, It diffuses from the alveoli into the blood.
Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.
Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.
Therefore, your answer should be C.
