The cell membrane is made up of a phospholipids that are arranged into two layers which are called lipid bilayer.
Yes.
The kidney is the part of the internal organ that help in the production of urine. And a normal urine should be yellowish in color.
Therefore, in a situation whereby the urine is seen to contain some red tiny droplets, specifically means the presence of an infection to the kidney.
In this case, a cloudy urine might mean the presence of white blood cell which stipulates the presence of infection.
Answer:
d. K+ and Na+ both diffuse into the cell along their concentration gradients and drive the transport of glucose.
Explanation:
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
