I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
The answer is <span>C. DNA controls the production of protein in the cell.
DNA is made up of nucleotides. The sequences of nucleotides carry information for the protein synthesis. DNA is stored inside the nucleus, one of the organelles present in all eukaryotic cells.</span>
Schemas refers to a cognitive frame work which help humans to organize and give interpretations to information obtained both from within and from the external enviroment. Schema guide human cognitive processes and behaviour. Schema helps in structuring our memories by acting as a glue which hold all the information we have gathered together. Shcema is used in recognizing new experience and in relating it with old experiences. Schema affects humans' perception, encoding, memory recall, etc.
A theory that states that only the organism with traits that are useful to the environment survive. For example, short-neck giraffes would’ve died out years ago as they can’t reach the trees nor eat grass on the ground.
