<span>While
unfortunately, this question is incomplete, it relates to processes that occur
in cells. Catabolic processes involve the breaking down of molecules to release
energy. In anabolic processes, this energy is used facilitate a succession of
chemical reactions to build up larger molecules from smaller component molecules.</span>
Answer:
D. Diffusion
Explanation:
The process of diffuse transports the substances in the direction of their concentration gradients. Diffusion of substance from the region of their higher to that of the lower concentration does not require any energy. Being a passive process, diffusion can be carried out by a cell irrespective of the status of its ATP supply. Therefore, an animal cell containing a small amount of cyanide can transport substances by diffusion.
Answer:
Oxygen
Explanation:
The formula for cellular respiration is oxygen + glucose -> water, carbon dioxide, energy. You can already cross out A and D because they aren't in the formula, so you have two left, water and oxygen. The reason why it is oxygen and not water is because without oxygen you can't even have water. also, I just got this right on my test :-)
Answer:
Dessert and tundra
Explanation:
Theses two biomes get very little rain and because of this they have a less diversity of fauna and flora.
The differences are that a tundra is very dry and extremely cold and on the other hand a desert is very arid and hot and it can go as high as 54°C (130°F).
Answer:
(A) -> (D) -> (C) -> (B)
Explanation:
First off, given that the problem requires us to explain how life on Earth may have arisen <u>from terrestrial origins</u>, we can discard sentence (E), as impacts from meteorites would count as extraterrestrial origins.
Then it's just a matter of describing the steps by which simple compounds turned into more and more complex structures, that would in turn lead to the origin of life.
Simple inorganic compounds (such as CO₂, or NH₃) were exposed to energy, because of that they formed simple organic molecules, like carbohydrates or amino acids.
These organic molecules, in turn, would self-assemble into more complex structures, such as proteins.
Lastly, there's the phenomenon of Compartmentalization, where large organic structures became enclosed within a membrane-like structure, separating them from the 'outside' medium and thus creating primitive cells.
