During a fight-or-flight response, epinephrine is released into the body’s circulatory system and transported throughout the body. Some cells exhibit a response to the epinephrine while other cells do not. Which of the following justifies the claim that differences in components of cell signaling pathways explain the different responses to epinephrine?

The cells with receptor will show the response to the epinephrine.

Explanation:

The cell signalling is the path which explains how the cell communicates and coordinate with the other cells present in the body.

The cell signalling represents the interaction of one cell to another which involves the chemicals called messenger molecules or hormones, the receptors and a transduction pathway.

In the given question, since the epinephrine produced by the neurons is transported to the target cells and shows its effect. Since epinephrine is a messenger molecule, therefore, it will bind to only those cells which will have the receptors for it. Since all cells do not possess epinephrine receptors, therefore, all cells d not respond to the molecule.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
