The cells of the brain's hypothalamus, which monitor blood salts, stimulate the pituitary gland to release antidiuretic hormone (ADH) whenever the salts are too concentrated or the blood volume or blood pressure is too low.
Active transport, specifically sodium-potassium pump. This pump uses energy to move sodium out of the cell and potassium into the cell against their concentration gradients. This process allows gland cells to maintain a higher concentration of salt internally despite the higher concentration in the blood.
False. While blood does contain some salt, the concentration of salt in blood is not as high as in the ocean.
the job of the kidneys is to filter the blood. it also regulates the salt concentration in your blood.
The macula densa in the distal convoluted tubule of the nephron monitors the salt (sodium and chloride) levels in the filtrate. It plays a role in regulating the release of renin from the juxtaglomerular cells in response to changes in salt concentration, helping to maintain blood pressure and fluid balance in the body.
If human blood is put in salt water, the water molecules in the human blood will lead to the lower concentration of water molecules. This process is called diffusion- water molecules going from high concentration to low concentration.
Osmosis would cause water to move into the red blood cells from the surrounding solution, which has a higher salt concentration than the cells. This movement of water would occur in order to balance out the concentration of salt on either side of the cell membrane.

Provided the concentration of salt is higher than the salt concentration in the red blood cell, the red blood cell, through the process of osmosis and the principal of diffusion, will shrink, as water flows from within the red blood cell to the solution
Only mammals have sweat glands, so the albatross doesn't have them. Its salt gland helps it to get rid of the heavy concentrations of salt it ingests with its food and by drinking ocean water. This is a much greater concentration of salt than what mammals handle via sweating, and of course, sweating's primary function is not to rid the body of salt, but rather to cool it, to produce scent, to protect the skin and hair, etc. Mammary glands are even a modified type of sweat gland.
Waste products diffuse from blood into a salt solution due to the concentration gradient between the two environments. When the concentration of waste products in the blood is higher than in the salt solution, diffusion occurs as molecules move from an area of higher concentration to an area of lower concentration. This process helps maintain homeostasis by removing waste from the bloodstream. Additionally, the presence of salt in the solution can influence osmotic balance, further facilitating the movement of waste products.
In terms of the salt concentration OUTSIDE the cell (in the medium), 0.15M NaCl would retain the normal condition of the red blood cell. Hope you liked it! :D
