Answer:
C. Synthesis of organic molecules
Explanation:
According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
Answer:
Active transport
Explanation:
Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.
