Algae will increase since the fertilizer has chemicals that will set with the water.

Toxic chemicals will rise since the fertilizer was made in a factory.

Not sure about fish tho because the lake can refill it's life after a while and the chemicals can work as a counter measure.

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.
