Answer:
20.3%
Explanation:
Given that:
An AAbb strain is crossed to an aaBB strain
i.e.
                    AAbb      ×      aaBB
gametes       Ab                   aB
For F₁ 
generation;   
If the resulting progeny are now self-crossed.
We know that the genetic distance between these two genes on the same chromosome is said to be 10 cM.
i.e. the recombinant gene = 10%; Hence, the parental gene will be (100 - 10)% = 90%
Ab ×   aB  =   Aa    AB      ab     Bb
From above; the parental gene;
Ab and   aB = 90% with each being 45%
i.e. Ab = 45%   and aB = 45%
while the recombinants genes are:
AB and ab = 10% 
i.e. AB = 5%  and ab = 5%
Finally; the percentage of aaBB is = aB% ×  aB% × 100%
the percentage of aaBB is = 0.45 × 0.45 × 100%
the percentage of aaBB is = 20.25%  ≅ 20.3%
 
        
             
        
        
        
A, strongly basic. i’m not sure if i’m right but oh well
        
                    
             
        
        
        
Answer:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. (Draw a plant and this is tghe one you underline)
A heterotroph is an organism that eats other plants or animals for energy and nutrients. (You can draw a dog, cat, frog or a person)
