The correct answer is option A, that is, extreme temperature changes between seasons.
If the planet B has an axis tilted at 45 degrees to its orbit of the sun the seasons would be more extreme. Some places on the planet would be in the night for weeks or months and others would be in the perpetual light for as far as long. The difference between the seasons is mainly because of axial tilt, so the planet would get colder winters and hotter summers.
Assuming that the trait of being able to taste the sample is a dominant trait, then the tasters have at least one of that dominant trait and the people who were not tasters had the homozygous genes for the recessive trait. Therefore, the answer is 10 - 30
The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"
