Answer:
65
Explanation:
An autosomal dominant condition is one where one copy of the allele is sufficient to cause the condition. Penetrance refers to the degree to which that mutation causes the phenotype
Lets say the allele for sharp beak is S and for normal beak is s. If 2 heterozygous sharp-beaked terrapins mate, the cross is the following:
Ss x Ss
<u> S s </u>
S SS Ss
s Ss ss
The possible genotypes are SS, Ss and ss. 50% of their offspring will be heterozygous, and 25% homozygous each. Therefore, if the mutation was fully penetrant, it would be 75 out of 100 offspring would be affected.
However, the mutation is only 87% penetrant, which means only 87% of those 75 offspring would have the condition.
87% of 75 = 65.25
Therefore, we would expect 65 of their offspring to have sharp beaks
I believe the answer is :C. tolerance
In this context, tolerance refers to your physical ability to handle the effect of foreign substance that come inside.
As you consume more of the substance, your body would adjust to increase its tolerance for that substance, which make you need more amount in order to feel the same effect.
The pressure to loosen clean air standards is based in allegations that the standards affect industry development and economy because the adjustments require further modernization and some industry even need to change their whole machinery or line production to be able to meet the legal requirements, as for the car industry, slowing down production or increasing costs.
In short-term that is very likely to be true, the industry will have to do some investment, but the price will be lower than the long-term cost of keeping up polluting the air.
The clean air standards should not be loosen because loosen the standards will benefits only specific groups and temporary, later and in other domains the loosen of the standards will affects human and other animals quality of life and environment. The economic impact will be seen later on healthy sector, food sector as agriculture and livestock, in nature disaster and in the lack of natural resources due to dramatic landscape changes.
We should not think about just economic impact of now when taking this decisions but we should consider systematic risks and consequences of supporting the loosen of clean air standards.
We must keep in mind that some process in nature are irreversible and when one action as the pollution of air is impacting towards things we will not be able to revert anymore the cost will be much higher in future than is now to adapt to the clean standards.
<span>Most clearly results from genetic predispositions. </span><span>Temperament is a set of peculiarities and forms of expressing emotions that a person possesses. It is related to the character of a person and defines the personality. <span>It has been proven that the temperament has genetic origins, that is why emotional traits such as shyness have genetic origins.
I hope my answer can help you.

The reason why one case of influenza does not confer lifelong immunity is that the virus tends to mutate overtime which makes it unrecognizable to the immune system.
<h3>Why is it difficult to get immunity to influenza?</h3>
Influenza is caused by a virus which tends to mutate overtime in order to stay ahead of medical technology.
As a result, this mutation makes the original virus unrecognizable to the immune system which would then be unable to fight it.
