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.

What is responsible for the yellow-orange coloration of leaves in the fall?
mixer [17]

The correct answer is - C) carotenoids.

The majority of the trees from the mid-latitude forests tend to shade their leaves in the autumn. This process occurs because of the seasonal changes in the climate, where the trees tend to be almost not-active during the winter, so in order to preserve as much energy and nutrients as possible they get read off their leaves.

It is not a sudden process, but it takes some time, where the leaves from the initial green color start to change to yellowish, than towards orange, reddish, or brownish before they fall.

The reason why this coloration appears in the leaves when the tree starts to process of shading them off are carotenoids. The carotenoids found in the leaves, the lutein and the beta-caroten, thorugh the xantophills and the flavonoids give a yellowish color to the leaves, thus we get the beautiful autumn colors and landscapes.
