Answer:
( a ) Voltage gated channels - channel can open and close based on membrane potential. At rest, the channel is closed and it opens at threshold.
Explanation:
Voltage Gated Channels -
It is a channel with a cluster of proteins present in the membrane .
The function of voltage - gated channel is to open for the some values of membrane potential and close for others . In maximum cases , the relation between channel state and membrane potential is probabilistic and requires a time lag . The ion channel can even flip the conformations at an unpredictable times , the membrane potential even determines the rate of transition and the probability per unit time of each and every transition .

<h3>Is it hospitalized or admitted to the hospital?</h3>
English phrases for hospitals include hospitalized and hospitalised. In the U.s, "hospitalized" is preferred over "admitted to hospital" (99 to 1). In the UK, "hospitalised" is preferred over "hospitalized" by a margin of 61 to 39.
<h3>Why do people end up in hospitals?</h3>
When a person has a critical or life-threatening issue, they are admitted to the hospital (such as a heart attack). Additionally, they could be admitted for less severe conditions that are untreatable elsewhere (such as at home or in an outpatient surgery center).

Answer:
The dermis is the second layer of the skin that protects the human body from stress and strain. It is found between the epidermis and the hypodermis or the subcutaneous tissues.
The dermis layer is composed of two layers: papillary dermis and reticular dermis.
The reticular dermis is the thick layer of the dermis, composed of the dense irregular connective tissues. It contains of elastic protein fibers that makes the skin stretchable and elastic (able to rebound).
<u>Therefore, the reticular dermis makes the skin stretchable and elastic (able to rebound).</u>

Phagocytosis - pseudopods are used to engulf large molecules or entire cells; performed specialized white blood cells and amoeba, not specific
Pinocytosis - cell membrane pinches inward and surrounds fluid containing solutes, not specific
Receptor-mediated endocytosis - chemical (LDL carrying cholesterol) binds to receptor protein before being brought into the cell; specific
