Answer:
(for 1st question)
Plato's answer: This world exists because both systems are involved in the movement and support of the body, and they work together to perform these functions. Bones provide support and give the body structure. Muscles give strength, and the contraction and relaxation of muscles allow for different movements.
Explanation:
Another Answer: The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
Answer: The correct answer is- Polymerase chain reaction.
Polymerase chain reaction is a technique in molecular biology that is used to produce multiple copies of a piece of DNA molecule through multiple cycles of three stages that are-
1) Denaturation- The two DNA strands are separated ( so that template DNA are exposed) at higher temperature.
2) Annealing- Primers ( forward and reverse) are attached to the template DNA.
3) Extension- New DNA strand is synthesized using enzyme Taq polymerase that adds dNTPs ( deoxyribonucleoside triphosphate) according to the complementary sequences in the template.
