Answer:
a = 20 m/s^2
Explanation:
F = m*a --> a = F/m = 320/16 = 20 m/s^2
The answer is diffusion.
The most important mechanism that enables oxygen and carbon dioxide (but as well other small molecules such as glucose, amino acids, wastes) across capillary walls is diffusion. Diffusion is a net movement of molecules through some barrier from an area of high concentration to the area of low concentration. When blood rich in oxygen reaches capillaries close to the cell, now there <span>is </span>more oxygen in the capillaries than in the cells and by diffusion, oxygen will pass capillary walls and enter the cell. Since blood in capillaries lacks in carbon dioxide, it will easily leave the cells and enter the blood. It should be taken into consideration that capillary walls may be fenestrated, continuous, and discontinuous which can affect movement through them.
<h2>Answer</h2><h3>C) The proteins involved in active transport must be powered by ATP to work.</h3><h2>Explanation:</h2>
If we talk about active transport mechanisms, it means that the proteins basically require the use of the energy, that energy is usually in the form of adenosine triphosphate (ATP). but if we talk about the facilitated diffusion, then the solute can move from the regions of lower concentration to the region of higher concentration. In this way, the proteins used for active transport different from those used for facilitated diffusion.
