By controlling what enters and leaves a cell, the cell membrane A) aids in maintaining homeostasis within the cell. Homeostasis is the process by which organisms maintain life through eating, growing, and living in variable conditions. It would not make sense to answer B) because organisms do not control the homeostasis of their external environment. D) also would not be correct because cell's do not control osmosis in the external environment. The membrane does not control osmosis because osmosis is generally a random process of molecular diffusion whereas the membrane acts in a conscious and controlled way.
It is asking for one trait or characteristic that can be seen visibly and environmental traits are characteristics caused by your geographic location for example African people have more melanin in their skin because they live closer to the equator and it protects them from getting sun burnt.
Answer:
Epinephrine is both a hormone and a neurotransmitter, so is considered a chemical that acts on the type of endocrine intercellular signaling.
Explanation:
Epinephrine, or adrenaline, is produced by the marrow of the adrenal gland, under the coordination of the central nervous system.
Epinephrine is a molecule that acts as a hormone or neurotransmitter, being able to achieve physiological changes by binding to specific cell receptors. This type of action generates changes inside the cell. As this molecule is produced in one cell and is coupled to the receptor of another cell, it performs the type of endocrine intercellular signaling.
