Answer:
To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:
         b        b
B   Bb         Bb
b   bb         bb
The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb. 
there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit. 
 
        
             
        
        
        
Answer: the answer is option A. 5 → 1 → 6 → 3 → 2 → 4
Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol,  SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses,  SRP binds to its receptor,   Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
 
        
             
        
        
        
Answer:
C
Explanation:
Our hair follicles hold DNA just as do our finger nails, saliva, and blood.
 
        
                    
             
        
        
        
Substitution mutation is when a single base pair in a strand of DNA is replaced. This can cause an early stop amino acid, or the protein could change slightly, or the protein could be unchanged completely due to there being multiple base pairs to make an amino acid.
 
        
             
        
        
        
False Because the frequency would increase
