It is C my brother. i legit just took the quiz rn! good luck. God bless
Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.
In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.
Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.
Although a part of your question is missing, you might be referring to this question:
Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major contributor to this phenomenon?
a. Recessive diseases are unmasked by additional copies.
b. The genes are found in a novel arrangement.
c. Gene dosage is modified.

It will cause vasodilation of blood vessels in the brain.
CO2 is one of the metabolic end products that can alter the
tone of the blood vessels in the brain. High CO2 levels cause vasodilation,
which may cause headache, whereas low CO2 levels cause vasoconstriction, which
may cause lightheadedness. The statements included in the other options are
incorrect effects.
Answer:
The correct answer is - option B.
Explanation:
The diversity of numbers of proteins in the human body is due to the differences in the structure of proteins. This change or difference in the structure of proteins is mainly affected by the sequence of amino acids.
The order of sequence of amino acid segment or residue in the peptide chain of the protein affects the structure of the particular protein which also leads to change in the secondary and tertiary structure of the protein.
Thus, the correct answer is - option B.
I don't think it will work.
Fish breathe with gill not lungs. Unlike lungs, gill works one way. You breathe out air out of you mouth but fish dump the water from their gill so they shouldn't be able to push water out of their mouth.
Even if the could fish push the water through their mouth, the gas exchange didn't happen because the water didn't move through the gill. The fish that giving water cannot breathe while giving resuscitation.
