A decrease in the resting membrane potential is __________ whereas, __________ is an increase in the membrane potential.
nexus9112 [7]

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.

Compare and contrast the structures of DNA and RNA
katovenus [111]

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
