Autotrophic behaviour depends on the ability of the cell to carry out photosynthetic or aerobic respiratory metabolism, which are the only processes able to deliver sufficient energy to maintain carbon fixation. The Calvin cycle is used by bacteria to synthesize organic compounds.
        
             
        
        
        
The correct answer to this question is this one: "<span>Since they eat lower on the trophic level and don't expend much energy they are able to grow larger."
</span><span>The giant baleen whales can grow so large because </span><span>they eat lower on the trophic level and don't expend much energy they are able to grow larger. </span>
        
             
        
        
        
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right? 
These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color". 
1.List the distances between each pair of genes: 
beak color and tail-feather length: 20 MU 
beak color and feather color: 16 MU 
tail-feather length and feather color: 4 MU 
2.Which two alleles are the farthest apart? 
(the one that is 20 MU apart) Y and L 
3.Which two alleles are the closest together? 
(the ones that are 4 MU apart) L and B 
        
             
        
        
        
Answer:
I would say it begins to multiply based on the picture below
