Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
The answers are A, B, & C. Steroid hormones have a
longer half-life than peptide hormones because steroid hormones ride on carrier
proteins in the blood. In other words, they
are bound to protein carriers that transport molecules across the membrane. They can also be stored temporarily in the adipose
tissue. And also, steroid hormones are sent to the nucleus where it regulates transcription
while peptides don’t require this process. This is the reason why the effects of
steroid hormones are exerted more slowly than peptides.
Answer:
DNA polymerases from human cells will denature under these conditions.
Explanation:
Under the PCR conditions described, DNA polymerase from <em>T. aquaticus </em>would be more effective than DNA polymerase from human cells. This is due to the higher optimal temperature of DNA polymerase from <em>T. aquaticus. </em>
