Sav [38]

Answer: 1. The resting membrane potential would become less negative (more positive).

Explanation:

Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane.  The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.  

In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.

Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).

Living organisms breathe oxygen into grow​
fredd [130]

Answer:

Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
