Answer:
            The right option for blanks is mRNA, amino acids and polypeptide chain (protein).
Reason:
             During protein synthesis first of all mRNA formation occurs from DNA template. Then mRNA come out from nucleus into cytoplasm and bind with ribosome, where tRNA come and binds to mRNA codon with the help of anticodons. and add amino acids. In this way a chain of polypeptide is formed.
        
             
        
        
        
Answer:
C. By creating laws or traditions that regulate hunting and fishing
Explanation:
Wildlife resources refer to wild animals (terrestrial, aquatic etc) in their natural habitat. Wildlife is an integral part of our society, however, they are being overexploited by human activities. 
According to the options in the question, one way to address the problem of over use of wildlife resources is by creating laws or traditions that regulate hunting and fishing. Laws that compel hunting and fishing, which are the means humans over use wildlife, will help bring the rate at which these resources are used. 
For example, creating a law that prohibits hunting in certain areas will help preserve wildlife in that area because it is a punishable offence by the law to hunt. Hence, wildlife resources will be preserved. 
 
        
                    
             
        
        
        
Answer:
In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees. 
 
        
             
        
        
        
Answer:
When a mustard plant seedling is transferred to an environment with higher levels of carbon dioxide, the new leaves have a lower stomata-to-surface-area ratio, it is because the concentration of carbondioxide is high in the surrounding so the plant produce small leaves having less number of stomata. If the concentration of carbondioxide is lower so big leaves are produced having maximum number of stomata.
