The answer to this particular question is A
Given question is incomplete. Complete question has been attached.
Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
Answer:
Cristae or Cristal membrane
Explanation:
Cristae is a structure in the mitochondria which is a fold in the inner membrane and its function is to increase the surface area of the inner membrane of the mitochondria, allowing for faster production of ATP
The statement that best represents how structure relates to function is as follows: a deer's horizontal pupils help it scan the horizon for predators (option C).
<h3>What is structure in biology?</h3>
A structure, according to biology, is an arrangement or organization of parts to form an organ, system, or living thing.
The structures found in living organisms are usually function-specific. Examples of common structures in living organisms and their respective functions are as follows:
- Radula in snails - feeding
- Eyespot in Euglena- light sensing
- Claws in carnivores- for holding prey
Therefore, the statement that best represents how structure relates to function is as follows: a deer's horizontal pupils (structure) help it scan the horizon for predators (function).
