B - They both use protein channels (I think so at least) they differ because active transports use a pump to leave the cell and it uses atp (cell energy).
Im going with Genes inserted from other organisms.
A diet high in protein and low in calcium may lead to osteoporosis. This is because protein, especially albumin, binds free calcium in the blood preventing it to be act upon calcitonin and preventing it to deposit in the bones. Low calcium predisposes patients in osteoporosis as there will be no calcium to be deposited in the bones.
Potassium is 10 to 20 times higher inside the cell, and sodium is 10 to 20 times higher outside the cell. The potential difference across the cell is important in several processes such as transmission of nerve impulses and maintain the ion balance.
The sodium concentration higher out side and potassium higher inside the cell then it moves two potassium into the cell where potassium levels are high and pump three sodium ions out of the cell and into the extracellular fluid.
This is due to action of membrane active transport system which pumps sodium out of the cell and potassium into it. Both helps in body maintain flid and blood volume so it can function normally.

The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
K.E = ½ × 1324 × 20²
K.E = 264800J
Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
