Answer:
A protein needed for blood clot formation.
Explanation:
Prothrombin may be defined as the protein that changes in to the thrombin during the process of blood coagulation with the help of clotting factor X.
The main function of the prothrombin protein is the coagulation of blood. This protein is responsible for blood clotting at the time of external and internal injury.
Thus, the correct answer is option (c).
Thermocline - <span>a steep temperature gradient in a body of water, that is marked by a layer above and below at which the water is at different temperatures.
halocline - </span><span> a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water.
pycnocline - </span><span>a layer in an ocean or other body of water in which water density increases rapidly with depth.</span>
Answer:
Option C
Explanation:
Given ,
A1 allele is carried by
% people
Let us assume A1 s dominant genotype
This means 
Thus, frequency of allele in the given population is 
It is also given that the population is in Hardy-Weinberg equilibrium thus

Frequency of fruit fly with genotype A2A2 will be

As per Hardy-Weinberg's second equation of equilibrium

Hence, option C is correct
Answer:
glutamic acid, because the R group could form ionic bonds
arginine, because the R group could form ionic bonds
tryptophan and tyrosine, because the R groups are small, allowing close stacking
glycine and alanine, because the R groups are small, allowing close stacking
