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.

Answer: the rabbit
Explanation:
In ecology, biomass refers to the mass of organisms living within a specific region at a time. Biomass is measured and usually described as:
- the total mass of the organisms within a community
- the average masses per unit area
Typically, more numerous organisms, such as producers, have a higher average biomass. This may include plants, animals or microbes such as bacteria and fungi. In terrestrial environments, biomass is distributed in pyramid form; the carnivorous hawk preys on rabbits and birds, which are nearer to the base of the pyramid- each predator population would have a lower biomass than its prey. 
The birds weigh 100 grams while the rabbit weighs 150 grams.The rabbit has a higher total mass
