Answer:
This is correct. The remaining portion:
Sympatric species that form interrelationships undergo coevolution.
Allopatric species in different environments can undergo convergent evolution.
Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.
Explanation:
On the basis of geographical distance, speciation is of two major types:
- Sympatric
- Allopatric
Sympatric Speciation:
Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.
Allopatric Speciation:
It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.
Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.
Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.
The answer is LDL (Low Density Lipoprotein)
Arteriosclerosis is the build up of cholesrol on the inner walls of the arteries. In the long run, arteriosclerosis reduces the diameter of the blood vessels, causing high blood pressure.
The endothelial cells of arteries have receptors that facilitate binding and transportation of the LDL hence facilitation of their accumulation in the blood vessels.
Do not worry so much about the why of classification. Classification is important because it is a lens through which to see what is there. It is not intrinsically true in and of itself. Distinctions are important only as vehicles for a common base of communication. All things have symmetry. A reflection has symmetry. Symmetry means organized life. Organized life is what happens when RNA replicates. It is the difference between chaos and order
