This is a symbiotic relationship between the Boxer crab and sea anemone. 
<h3><u>Explanation</u>:</h3>
The symbiosis is a type of relationship between two species which has benifit for both the participating organisms.
Here in case of boxer crab, the crab gets the help from the sea anemone in the form of protection. The sea anemone chases the predators and thereby saves the organism from being hunted. 
On the other hand, the sea anemone gets food from the crab's prey which he hunts.
So there's a benifit for both.

All three are bad for the environment because all three types release CO2 into the air and have throughout their constant usage helped with creating the greenhouse effect that traps heat and causes global warming. That's why clean energy is a necessity and people are developing harnessing wind and solar power.
        
             
        
        
        
Awnser:
She has two different alleles for eye shape, one from each parent
You always receive 1 allele from each parent, and you're heterozygous, those alleles are different.
