Sodium and potassium ions move in and out of the axon when the membrane is ______
Ostrovityanka [42]

Answer:

Answer : Depolarized

Explanation:

Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.

A change in polarity occurs in the axon membrane when a nerve impulse travels across it.  At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.

How many nucleotide bases differ between your sample (labeled as O. Kisutch) and the standard sequence for O. Kisutch? Sample la
OverLord2011 [107]

The right answer is 3 nucleotide bases.

5'-CGGCACCGCCCTAAGTCTCT-3'

5'-AGGCACCGCCCTAAGTCTAC-3'

It would be necessary first to align the two sequences side by side so as to be able to compare them, and they should also be in the same direction.

The nucleotides marked in bold are the nucleotides that differ between standard and O. Kisutch.

These nucleotide changes are necessarily due to substitution mutations that exchanged one nucleotide for another in the same location.
