Bodily functions that help keep it stable. Like sweating when your are hot keeps your body at a cooler temperature rather then burning up.
C...the key is that they are photosynthetic...so they produce oxygen (like plants)!
Explanation:
Water is H2O, two hydrogen atoms for every oxygen atom. ... Then, the hydrogen and oxygen can be stored and eventually burned together in a rocket engine to provide thrust for the mission. That is the kind of fuel used by the Space Shuttle's main engines.
When the circular muscles contract, the earthworm stretches, becoming longer and thinner. The earthworm uses its setae to anchor the front of its body in the soil. Now the longitudinal muscles contract and the earthworm becomes shorter and wider or it bends from one side to the other, pulling the body forward.
All cells have at least one strand of DNA. prokaryotic cells are single celled, plants have a cell wall and vacuoles, animal cells have a centrosome. smooth or: synthesize lipids, metabolized carbohydrates, store calciumrough or: has bound ribosomes, produces proteinsGolgi apparatus: flattened membrane sacs, modifies products of the ER manufacturers macromolecule sorts. lysosomes: membrane sac of hydrolytic enzymes, hydrolyzes proteins, mitochondria: power house of the cell, makes ATP and such chloroplasts: allows photosynthesis to be a thing
