Details:
The purpose of the gallbladder is to break down fat during digestion and to help the body get rid of waste.
The most common type of gallbladder malfunction occurs when cholesterol solidifies into gallstones. WHen the gallstones become large, they cause colic or severe pain in the upper body.

not sure but I think it's option C.
Answer: D) constructive process
Explanation:
Deposition is the geological <u>process</u> in which sediments, soil and rocks are <u>added</u> to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, <u>building up</u> layers of sediment.
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.
