Answer:

D) Na+ is used to repolarize the membrane.

Explanation:

Option D is wrong choice because it is K+ which is used to repolarize the membrane not Na+.

As soon as membrane gets depolarized because of influx of Na+ due to opening of voltage gated Na+ channels simultaneous opening of voltage gated K+ channels and closing of Na+ voltage gated channels takes place. As a result of which K+ moves out of the cell leading to drawing of electrochemical gradient out of the cell.

In order to achieve resting membrane potential, more Na+ must be out of the cell and more K+ must be inside the cell. There are many leaky channels on neurons from which Na+ has tendency to leak into the cell while K+ has the tendency to leak outside of the cell. So Na+/K+ pump which is located on the membrane of neuron keeps pushing Na+ outside of the cell and K+ inside the cell so as to maintain resting membrane potential which is -70 mV.

sergey [27]

Answer:

D

Explanation:

Units of weight and volume won't be large enough to be meaningful. so liters and grams are too small. Find out the weight of a cubic meter of water and then estimate how many cubic meters there might be in a lake. Millions would probably be too small.

Miles are too big. Most lakes do not go to a depth of 1 mile, but you on on the right track. Distance is what you want.

Meters are the answer.

WILL MARK BRAINLIEST GIVE ME A 3-4 SENTENCE EXPLANATION OF WHAT IS PHOTOSYNTHESIS
Natalija [7]
Photosynthesis is a process plants and other organisms use to create energy. The energy from sunlight, glucose, water, oxygen, and carbon dioxide are used by the plant to photosynthesize. These chemicals work together within the plant and produce energy. Oxygen is a product of photosynthesis that benefits humans and animals. Photosynthesis is essential for most plants to live.

Similar to making a double batch of cookies, in order for a cell to divide it must have double the contents that it normally has
Vinvika [58]
<span>The cell cycle is divided into two main parts interphase and mitosis. Mitosis is when the cell divides and this process is taken up by the process of dividing. Interphase is broken down into several phases: G1, growth occurs (cytoplasm increases); S, DNA synthesis (replication) occurs; and G2, growth occurs (cytoplasm increases and organelles are replicated). So the answer is b) Cytoplasm increases, and organelles and DNA are replicated</span>
