Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
Answer:
D
Explanation:
Addition of hydroxide ions will decrease its acidity and make it more basic.
It's the definition of a SPECIES.
Those animals are from the same species.
They both take place in the nucleus :)
You could say DNA is found in both viruses and in living single-celled organisms because DNA is necessary to replicate itself.
