Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
<span>The types of skeleton depend on where they are located. Earthworms have hydroskeleton because their rigid bodies are based on water pressure so it's hydro then. Endo is found in animals like birds and also humans who have it inside. Exo is found in spiders because they are bugs and bugs have their skeletons like a shell that covers them.</span>

Answer:
It encapsulates the idea that all the particles of matter in the universe attract each other through the force of gravity – Newton's law tells us how strong that attraction is.
(sorry not sure)
Answer:
The correct answer would be ATP.
ATP (adenosine triphosphate) is an energy currency of the cell, that is, it provides energy for all cellular activities.
Muscles also get energy in the form of ATP for movement.
Usually, simple sugar such as glucose is oxidized completely to produce ATP.
Then, ATP hydrolysis releases energy in the form of heat which is used by cells to perform various functions such as movement, repair, et cetera.
