Answer:
Processing and storing food.
Explanation:
The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.
The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.
The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.
Thus, Processing and storing food is correct.
B) because it is just the equation one step ahead (if that makes sense)
Answer:
Extension
Explanation:
Polymerase chain reaction is given by Kary Mullis and it contains three steps denaturation, annealing, and extension. In denaturation, the temperature is raised to 96° c so that the DNA can denature.
In annealing, the temperature gets reduced to 55°c so that the primer can bind to the complementary sequence. In extension, Taq polymerase is used to extend the new strand.
This enzyme is isolated from thermophilic bacteria and the temperature here is raised to 72°c so that the enzyme can extend the primer and make the complementary strand. So the right answer is extension.
