Answer: Hemoglobin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.
Answer:

a conscious mental reaction (such as anger or fear) subjectively experienced as strong feeling usually directed toward a specific object and typically accompanied by physiological and behavioral changes in the body.
Answer:
33%.
Explanation:
The 4% population is red-hair due to the recessive mutation in melanocortin 1 receptor (MC1R).
Since, the population is in Hardy-Weinberg equillibrium- laet the frequency of recessive allele with red - hair is 'q' and the frequency of dominant allele in the population is 'p'.


q=0.2
According to hardy-weinberg equillibrium
(p+q)=1
p=1-q
p=1-0.2
p=0.8.
The total population with non red hair is calculated by
=
= 0.64 + 0.32
= 0.96
The percentage of the population with non red headed carrier for MC1Rr is calculated by:
=0.32/0.96*100
=33%
Thus, the correct answer is (B).
Answer:
<u>Temperature</u> is most likely the reason of protein unfolding (denaturation).
Explanation:
In the figure attached, coiled (3-dimensional) protein structure is changed to 2 dimensional structure in which protein is unfolded. This is most likely the result of heating proteins which destroys the hydrogen bonds and non-polar hydrophobic interactions that are necessary to establish the tertiary structure of proteins. Principally, increased temperature results in the increased kinetic energy of atoms within a molecule. If the amount of heat is sufficient to break the hydrogen bonds, protein molecule can unfold to 2D structure as shown in the figure.
