Chemical x is a hydrophilic germination inhibitor. what would be the advantage of having this chemical in the seed coat?

Answer;

The chemical would allow for germination when there was sufficient levels of moisture in the soil.

Explanation;

-Germination inhibitors are substances produced by plants or substances of related structure not found in plants which inhibit or delay the germination of seeds of plants.

-Besides inhibitors, high osmotic pressure and acid pH are often partly responsible for the germination inhibition caused by sap, juices and extracts. The main known inhibitors are the following substances or belong to the following chemical groups: hydrogen cyanide, ammonia, ethylene, mustard oils, organic acids, etc.

-A chemical x which is a hydrophilic germination inhibitor, thus, it would allow for germination when there was sufficient levels of moisture in the soil.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
