B. giant impact.....
b. Once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accomodate the product.
c. Once the enzyme binds to a specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
A) 1
B) 2
C) 4
D) 8
E) 16
Since there are four alleles, there are four different combinations of alleles possible in the gametes. Therefore, option C is correct. as there would be four different types of gametes possible in this system.
In a system where skin color in a certain species of fish is inherited via a single gene with four different alleles, the number of different types of gametes that would be possible can be determined using the principle of independent assortment.
The principle of independent assortment states that during gamete formation, the alleles for different traits segregate independently of each other.
Since there is only one gene involved in determining skin color in this case, we can assume that the alleles for skin color segregate independently as well.
With four different alleles for the skin color gene, let's label them as A, B, C, and D. Each individual gamete will carry only one allele. The possible combinations of alleles in the gametes can be calculated by multiplying the number of alleles for each gene together.
In this case, since there are four alleles, there are four different combinations of alleles possible in the gametes. Therefore, the correct answer is C) 4, as there would be four different types of gametes possible in this system.

Answer:
The correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.
Explanation:
Dr. Smith has found the bird that he considered as new species however Dr. Wilson said he will only be convinced if DR. smith could find several members of the same species. Dr. Wilson seems to be sure before considering the bird that Dr. smith found as the new species. It is because he wants to sure if it's not an unusual example of the pre-described species.
Thus, the correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.
