An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
B. Jet streams are very powerful air currents, and it's very inconvenient for a plane to have to go against the direction of a current. They have to plan their flights to avoid these currents or be aided by them.
Answer:Procedures. Ask students to guess how far away the Moon is from Earth. When the answer (or a close approximation) is given, or several guesses have been made, share the distance with students (384,400 kilometers or 238,855 miles).
Explanation:
The role of mitochondria is to supply energy to the cells
Which is which is why the answer is A. The powerhouse of the cell
Mithochondria can transfrom oxygen to generate energy for the cell. For example, brain cells in our brain need a lot of energy to process all the information what we inputted, thats when mitochondria took part.
Answer:
the proton gradient will decrease
Explanation:
The proton concentration gradient is generated across the inner mitochondrial membrane. It is maintained since the inner mitochondrial membrane is impermeable for protons. Therefore, intermembrane space has a higher concentration of proton than the matrix. The opening of UCP1 that facilitates the diffusion of protons would dissipate the proton concentration gradient as protons will move back to the matrix through the opened channels. The proton concentration will be lost as heat.
