What possible genotypes will the offspring have if the parents' blood types are O and AB?HELP PLEASE!!!

Natural selection and genetic drift are two mechanisms of evolution that can lead to speciation. Define both natural selection a

<h2>Evolution </h2>

Explanation:

Genetic drift

Genetic drift is change in allele frequencies in a population from generation to generation that occurs due to chance events
The genetic drift occurs due to random fluctuation of any allele in a gene pool and is more efficient in small population
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population which means they may experience strong drift for generations
In founder effect a genotype from a homogeneous gene pool migrate to a newer habitat and colonize there and form a newer community which leads to the genetic drift to the original population, speciation which occurs in this effect is the peripatric speciation
In bottleneck effect the elimination of inferior genotype from a homogeneous gene pool occurs due to the strong selection pressure and changing environmental conditions which leads to genetic drift and a only a few most adapted genotype survives and flourish

Natural Selection

Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
Genetic drift, mutation and sexual selection are important causes of natural selection
Directional natural selection favours the superior genotype and eliminate the inferior and intermediate genotype, in the history of evolution the most common natural selection is directional natural selection
Stabilizing natural selection favours the intermediate genotype but eliminates the extreme genotype
Bidirectional natural selection favours the extreme genotypes but eliminate the intermediate genotypes

Plate a and plate b are both continental plates what is the most likely result if the two plates collide

kaheart [24]

It depends what kind they are. Continental or oceanic, so if its those ones then the oceanic plat will most likely go under the continental so a subduction fault would occur but if its 2 oceanics or continentals then one would probably snap from the pressure or they will both go upwards creating a mountain range. I hope this helps

Describe the relationship between ATP and ADP and the importance of this relationship within a cell.

Helen [10]

Adenosine TRI phosphate (ATP) while ADP is adenosine DI phosphate. ATP has a third phosphate group stuck on the end of the molecule. Phosphates are big, bulky moieties, and it is hard to add a third group onto an ADP molecule that already has two. Also, they have a strong net negative charge - so that makes it doubly hard to push negative charges together. So the bond between the third phosphate group and the rest of the ATP molecule is very high energy - it takes a lot of energy to form it. A

Muscles help keep blood flowing normally through the body. How do muscles accomplish this task?

bezimeni [28]

Answer:

Option A, by having a constant supply of blood

Explanation:

Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed. During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.

Hence, option A is correct
