Answer:
Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins
Explanation:
.
Ice core can tells various information regarding the atmosphere. It can reveal the temperature, precipitation, and other atmospheric conditions. Here in the image, the scientists can learn about the ocean surface temperature, i.e., option D.
<h3>What is an ice core?</h3>
Ice cores are ice-drilled cylinders made from ice sheets and glaciers.
They are capsules that are frozen and allow scientists to reconstruct climate far into the past.
It can be used to detect the ocean surface temperature.
Thus, the correct option is D.

A.) Mitosis
In cell biology, mitosis is a part of the cell cycle when replicated chromosomes are separated into two new nuclei
<u>Answer:</u>
<em>Sodium will move from the inside of the cell to the outside of the cell by diffusion.
</em>
<u>Explanation:</u>
A <em>difference in concentration of a substance</em> in two regions induces movement of that substance from the area of high concentration to the <em>area of low concentration</em>. Since the movement is according to a concentration gradient there is no need for energy expenditure. <em>This is called passive diffusion.
</em>
In this case passive diffusion of sodium will occur. If a substance has to be moved against its concentration gradient energy is required and this p<em>rocess is called active diffusion.
