Answer:
Option C
Explanation:
Given , 
A1 allele is carried by  % people
 % 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
 
        
             
        
        
        
Cells become haploid in cytokinesis of meiosis one because the chromosomes have divided. 
        
             
        
        
        
Answer:
 (D) Z
Explanation:
Cellular respiration is a catabolic process by which cells produce energy by oxidising respiratory substrates such as glucose. It is a multistage process occurs in cytoplasm and in mitochondria of a cell. The first stage of cellular respiration is called glycolysis or EMP (Embden, Meyerhof and Parnas) pathway. This stage occurs in the cytoplasm of a cell which is labeled by Z in the given image.
