An inhibitory stimulus has occurred. B. Chemically gated potassium channels have opened. C. Excessive potassium has diffused out
andrezito [222]

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.

This indicated that Photosynthesis was occurring.

Photosynthesis- Green plants employ a process called photosynthesis to produce their own sustenance. Life on Earth depends on photosynthesis. Without it, there wouldn't be any green vegetation, and there wouldn't be any creatures either. Interactive. Sunlight, <u>chlorophyll</u>, water, and carbon dioxide gas are necessary for photosynthesis.

Chlorophyll- Chlorophyll is a pigment found in certain living creatures and all green plants. It is necessary for the process of photosynthesis, which turns light energy into chemical energy. The pigment chlorophyll is what gives plants their green color.

Pigment- A chemical that may be found in animal or plant tissue and gives off a distinctive color, such hemoglobin in red blood or chlorophyll in green plants.
