Answer:
<u>Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon</u>
Explanation:
Remember, the term "ecotypes" is used to refer specifically to the observable differences found in the various kinds of whales, which includes <em>their breeding populations, their language of communication, social structure, the type of food they eat, and their hunting behavior.</em>
Thus, in the case of transient and resident killer whales in the Northeast Pacific, they are thought to represent different ecotypes rather than different species the Transient killer whales prey (feed) on marine mammals, while resident killer whales prey on Chinook salmon. Also, whales are generally thought to belong to the same species.
 
        
             
        
        
        
Answer: Cognition 
Explanation:
The sensual caress evokes a different somatosensory cortex response when the action is performed by the women to men but when the same action is performed by a men to men. There is no such response, this is because of the cognition response.
In this the person already has the response in the mind. These responses are generated at the time of reading , listening to radio, some touch of opposite sex.
Hence, the correct answer is Cognition.

Answer:
The first genetic code is used to determine the nucleotide triplets that code for amino acids.
Explanation:
The second genetic code is used by the amino acid synthetase in order to determine whether the correct tRNA is being used for it's corresponding amino acid. 
 
        
             
        
        
        
Answer:
b. forward mutation, suppressor mutation
Explanation:
When the nucleotide sequence of an organism is altered, it is called as mutation. It can be caused by DNA damage or replication errors. In forward mutation, the wild type allele is converted to a mutant version such that the gene product is non functional or its not produced at all. Suppressor mutation is the second mutation which reverses the phenotypic effects of the previous mutation. This process is called as synthetic rescue. 
Since here gene X was converted into a mutant form by the mutation, it had undergone forward mutation. When gene Y was mutated, the function of gene X was  restored which ultimately also restored the phenotype hence it is an example of suppressor mutation.
