Answer:
Proton motive force, compounds such as ATP.
Explanation:
Large amount of proton motive force(PMF),the usable enegy for the cell ,are produced during electron transport chain when high energy compound such as ATP pump hydrogen ions against the concentration gradient.
When the protons are transported against their concentration gradient at that time proton motive force is generated.
PMF generates energy for the synthesis of ATP by the phosphorylation of ADP with inorganic phosphate.
Answer:
Fertilization
Explanation:
Fertilization may be defined as the process of formation of zygote by the fusion of male and female gamete. Fertilization is an important event of the sexual reproduction.
The haploid stage (gametes) that fuse together and forms the diploid stage (zygote) in alternation of generation. The zygote is the individual offspring of the result of fertilization.
Thus, the correct answer is option (3).
Answer:
11B (reproduce). 12C (be eaten). 13A (variation). 14C (better adapted). 15C (Darwin). 16A (evolved). 17C (competition).
Explanation:
11 - The key principle underlying evolution by natural selection is that traits are only passed on if the organism survives long enough to reporduce. An adaptation that increases its likelihood of survival will therefore increase the chance it will reproduce.
12 - Deer rely on their brown fur to remain camouflaged in the forest so that predators can't see them. A white deer will stand out and will be seen by predators and eaten.
13 - This is the definition of variation. The variation becomes an adaptation if it actually benefits the organism in some way in its environment. A variation could also be neutral (doesn't affect the organism) or deleterious (bad).
14 - See previous question.
15 - Darwin developed the theory.
16 - This is describing the process of evolution.
17 - This is an example of competition.
Answer: Evolution
Explanation:
Evolution can be defined as the change in the characteristics of the species over a period of time which basically relies on the process of the natural selection.
The characters that allows the survival of the organism is favored and is known as the survival of fittest which is a natural selection.
This is known as evolution in which the herbicide resistant plant is favored more and has developed over a period of time.
