Answer: B 
Explanation: Multiple different combinations of bases (A, G, C, T) can code for the same amino acid. This means that there are more possible combinations of the bases than there are amino acids. There are 20 amino acids and the four bases can have up to 64 different codon combinations.

Explanation:
The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.
 
        
             
        
        
        
Answer:
Decrease in genetic diversity reduces the chance of variation in the offspring. 
Explanation:
If there is no variation, there will be no evolution. So, if there is a change in the environment (like an outbreak of a disease) that affects one of the organisms, it is likely to affect all of them and destroy the whole population. This would lead to extinction.
