Answer:
D) How do living things get energy?
G) How are living things related?
F) Where do living things make their home?
Explanation:
Different types of organisms are present on this Earth which interact with both abiotic and biotic factors and influence the nature of the environment. So there is a need to study the living organisms in which the first thing is to arrange the living organism by a process called classification.
The questions that are necessary to classify the organisms include related to the mode of energy or nutrition, the relation between various species at the morphological and molecular level, the habitat. The relationship between the organism is a very important aspect as it makes the classification easily according to their similarities and dissimilarities.
Thus, the selected options are the correct answer.

Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.
