Chemical: Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances.
Nuclear: Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
Kinetic: Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy.
It would be awesome if you marked brainliest! :)
When water molecules
diffuse through a cell membrane this process is called the osmosis. Water
molecules are extremely small and because of this they can slip freely through
the gaps between the phospholipids in the cell membrane. And as a result, water
molecules can constantly move back and forth though the cell <span>
membrane. This movement of water has a very important
function and that is it enables cells to absorb water. </span>
Now for a movement of
water molecules to happen, there should be a concentration gradient in the surrounding.
That is, the amount of water in one side must be different on the other side.
<span>For water to diffuse
INTO the cell, the amount of water outside the cell membrane should be larger
than the amount of water inside the side.</span>
Answer:
Lactase
Explanation:
Lactaid is a medication that contains the milk protein digesting enzyme Lactase. It is an enzyme supplement for those people who have trouble in digesting milk and other dairy products. Such condition occurs in Crohn's disease and termed as lactose intolerance. Lactase specifically acts on the lactose containing substrates and digests them by enzymatic activity. So people with lactose intolerance can be able to take dairy products with the help of Lactaid.
Cutoff signals are signals used by the animals for communication between them. These signals are behaviors. Examples are: the animal freezes, turns the back to other animals, moves away, ....
Cut-off signals are usually given after a conflict. One reason animals use cutoff signals is to:
D. encourage compromise between potential adversaries
If cut-off signals are not respected, conflict will escalate.
