If the allele encoding polydactyly (six fingers) is dominant why do most people have five fingers?

Biology
1 answer:

4 0

Answer:

The polydactyl allele is very rare in the human population.

Explanation:

The dominant alleles are expressed in both homozygous and heterozygous states. However, the harmful dominant alleles or the dominant alleles that do not impart the survival and/or reproductive advantages to the individuals exhibit lower frequency in natural populations.

The allele for polydactyly is dominant but is present in lower frequency in the natural human populations. Being a less frequency dominant allele, it is not expressed in most of the individuals. So, most of the individuals have five fingers instead of having six.

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.
Wewaii [24]

Answer:

The correct option is BLOOD CALCIUM LEVEL.

Explanation:

The options attached to this question are given below:

A. Filtration membrane integrity

B. Systemic blood pressure

C. Blood calcium level

D. Renal artery/arteriole diameters

Kidney is an excretory organ, which functions by filtering waste products out of the blood. The rate at which the kidneys filter the blood depend on some factors; such factors include: water intake, systemic blood pressure, vasoconstriction, dehydration, filtration membrane integrity etc.

Blood calcium level does not have any effect on the rate at which the kidneys filter the blood.

nekit [7.7K]
The answer is catastrophism.

Catastrophism is a theory explaining that the Earth has been affected by sudden catastrophes which created its geological features. Some of the proposed catastrophes is a global flood followed by an uplifting of some rock which happened sudden, in a short period of time.

1. The correct answer is; are body cells is going to shrink. <span>Salty seawater is a hyperosmotic solution, meaning that it has more solutes than the cell inside. The water will move (from the cell) via osmosis in order for the solutions to reach equilibrium. Also, salty solution exerts more pressure on the of the cell, so the cell will shrink.</span>
<span>
2. The correct answer cells in the fish will stay the same size. This will occur because both solutions, freshwater lake and river have similar (or equal) solute concentrations. Those solutions are called isosmotic. There is no movement of water or the solutes, so the cell stays the same.</span>

3. The correct answer is to swell. <span>This will happen because sea star egg has the same solute concentration as its first environment-ocean meaning that this solution is hyperosmotic comparing to the lake (ocean is saltier than the lake, it has more solutes). When you put the sea star egg in the lake, the water from the lake will move (via osmosis) into the egg, to reach equilibrium. Water will cause the cell to swell.</span>
