The endocrine system is made of glands that secrete hormones. These hormones help regulate the organs and cells activity. The hormones among other things control your metabolism.
<span>Atherosclerosis is a common cause, because there is a lack of blood flow in the person's body, and this can cause a male to be impotent.
Diabetes is also a common cause because once again it causes less blood flow.
In a younger man, a cause could be anxiety. This is because nervousness and being anxious can lessen blood flow.
If you have choices, I suggest choosing one that has to do with less blood flow happening, which that is the main cause.
I hope that this could possibly help you with your studies, and have an amazing day. If you have any more questions, send me a pm. </span>
Answer:
on channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms. In multicellular organisms, cells send and receive chemical messages constantly to coordinate the actions of distant organs, tissues, and cells. Cells can receive a message, transfer the information across the plasma membrane, and then produce changes within the cell in response to the message. Single-celled organisms, like yeast and bacteria, communicate with each other to aid in mating and coordination. Cellular communication has developed as a means to communicate with the environment, produce biological changes, and, if necessary, ensure survival.
Answer:
C
Explanation:
Mitosis is a growth division unlike meiosis which an organism undergoes to produce gametes or sex cells during sexual reproduction.
Mitosis is a kind of cell division that results in two daughter cells, identical in genetic composition. An organism can undergo mitosis in asexual reproduction. For each mitotic division, two daughter cells emerge (duplication division), which will propagate the number of the species.
In a case of heavy predation, the prey organism will depend on diverse number to keep its species from getting extinct. Hence, undergoing mitosis to duplicate itself asexually will be most beneficial in this scenario as a large number will increase the chance that some of them will not be a victim of predation.
