Great question! Let me first talk about how sedimentary rocks are formed. Sedimentary rocks are formed when when existing rocks are broken down in sediment. Now, let me explain what they are. Sedimentary rocks are rocks that have been weathered into rock fragments or pieces.

Answer:
b. the bottleneck effect.
Explanation:
The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.
The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.
The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.
Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
<span>Answer:
Is grossly bloody appearance and has a pH of 6
Rationale: Leakage of CSF from the ears or nose may accompany basilar skull fracture. it can be distinguish from other body fluids because the drainage will separate into bloody and yellow concentric rings on dressing material which is also known as halo sign</span>
I believe the answer is B. Hope I help! Sorry if not. ):)
