Answer:
So that that too much heat is not wasted
Explanation:
The bodies need to store their energy for the times when we need it. 
 
        
             
        
        
        
Answer:
 introns will remain inside the bacteria
Explanation:
Introns  are the remains of an RNA transcript that do not involve in coding and hence they are trimmed off once the protein is translated from the RNA molecule. 
Introns are found more commonly in eukaryotic genomes as compared to bacterial and archaeal genes
Group I introns have an ability to invade tRNA, rRNA and protein  through its intervening sequences however their insertion into genes is phenotypically neutral.
 
        
                    
             
        
        
        
In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers. 
 
The percentage of energy transferred to the deer after feeding on the grass is 10%. 
 
The 10% law of the energy states that:
1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat. 
 
2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy. 
 
Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law. 
The correct answer is Option C.
