When stimulated by the binding of specific chemicals, the membranes of taste bud receptors and olfactory neurons?
hoa [83]
Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.

krok68 [10]
<h3>Three tools Oceanographers use</h3>
  • Thermometer
  • Radar
  • Sonar

<h3>Functions of the tools.</h3>
  • Thermometer helps to measure the temperature of the ocean. Temperature  usually varies according to the season.

  • Radar helps to measure ocean currents and and it works under any type of weather condition.

  • Sonar is an instrument used to accurately measure the ocean depths through the use of sound waves.

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.
