Answer: Closed
Explanation:
At resting membrane potential( RMP) sodium channels remained shut, this is because , previously in depolarisation,the voltage gated sodium channels were opened for sodium to diffuse into the Axon. However these channels closed after reaching their refractory period,s.
Therefore a change in the extracellular concentration of sodium will not open them
The answer is B
Explanation. The density explains the amount of mass for how small or large an object is. Best way to test density is with water. If it is MORE DENSE (heavier in small area) it will sink.
Plasticity is to be molded. You can mold plastic is is bendable and heats up easily to give the advantage of being reshaped
Answer:
Species
Explanation:
According to the binomial system of nomenclature, an organism has two names. The first part of the scientific name is the name of the genus followed by the name of the species. A species is a group of organisms that can interbreed to produce new fertile offspring.
In other words, the term homeostasis is being used to describe the body’s maintenance during resting conditions whereas the term steady state refers to the body’s maintenance<span> during exercise; exercise is a stressor which disrupts homeostasis, also called homeostatic disturbance (e.g. an increase in temperature).
</span>Homeostasis is the maintenance of a constant internal environment (the immediate surroundings of cells) in response to changes in:
the changing conditions of the external environment.
the changing conditions of the internal environment.
Homeostasis is a self adjusting mechanism involving feedback where the response to a stimulus alters the internal conditions and may itself become a new stimulus.
<span> Homeostasis works to maintain the organism's internal environment within tolerance limits - the narrow range of conditions where cellular processes are able to function at a level consistent with the continuation of life. </span>
