Because in that way we keep thinking about them. How can you forget something when you're thinking about it?!
Answer:
See the answer below
Explanation:
<em>Hemophilia typically affects more males than females because the disorder is </em><em>X-linked </em><em>and </em><em>recessive</em><em>. </em>
<u>Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles. </u>
Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected.
In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females.
Answer: B
Explanation:
The question wants to know what the expression is directly dependent on.
The sequence of genetic expression goes like this:
DNA -> RNA -> protein
If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.
The Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.
Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.

Answer-
All the bonds are hydrogen bonds and this bond is strong
