Here, given-
homozygous alleles 'a' have a frequency of 0.3.
Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.
The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.
Calculation-

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

 
Thus, the individuals homozygous for the allele can be calculated by

Answer:
D
Explanation:
So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).
So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function
 
        
             
        
        
        
Answer:
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing.
