The answer is B.  This is because baby dolphins, when born, can't really comprehend a lot of things yet, so they, and the more adult dolphins there, try to get to the surface of the ocean to take a breath.  :D  I hope I helped!

When you drink sea water, what type of solution do you expose your cells to?
Alex Ar [27]
The answer should be 1, hypertonic. 

Seawater is highly concentrated in salt, and with that being said, it has a low concentration of water molecules. 

Hypertonic means the solution has a lower water concentration than the other side (cell), vice versa for hypotonic, a high water concentration than the other side of the solution, and for isotonic, it means that both sides of the solution have the same water concentration. 

So, the answer should be 1, hypertonic. 

In addition, when your cells are exposed to hypertonic solution, the water molecules in your cells will start flowing out of the cells, to the outside, due to the difference in water concentration leading to osmosis. Your cells will lose so much water that they may even shrink!

Water can move freely through the membrane from a higher to a lower concentration in a transportation process called _____.
nignag [31]

Answer: The correct answer for the fill in the blank is osmosis.

Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute is lower to a region where the concentration of solute is higher though a semipermeable membrane.

In other words, it is the water movement from an area where its ( water ) concentration is higher to an area where its concentration is lower.

This process does not require any energy as water is moving along the concentration gradient.
