The basis of the process of Natural selection is the random mutation: some organisms develop random mutations which increase their chance for survival and they survive more likely than other organisms and reproduce.
So the correct answer is:
A) Through random mutations in DNA, some pests developed a resistance to the pesticide.
Answer: Dominance of Gene for Bright Yellow Coloration.
Explanation: Gene carries the genetic makeup of a particular organism. It house all the information of all living organisms.
According to the phenomenon expressed by Gregor Mendel (law of Inheritance), genes are divided into two; dominant and recessive. The gene responsible for bright yellow color is more dominant in ascending generation of the frog which translates that gene responsible for green color is recessive.
DNA -- RNA -- TRNA--- amino acid--- protein
DNA (DeoxyRiboNucleicacid) creates RNA (RiboNucleicAcid) which is DNA basically cut in half vertical this then is "translated into a code of amino acids" by TransferRNA then these codons (3 bases grabbed by transferRNA) are turned to amino acids from there after the sequence is done you have a protien full of information on what to do
