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:
Key points
Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell.
Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.

Answer:
A. The sun
Explanation:
The sun, because there has been theory’s of the sun being able to heat earth from there being a lot of iron in the middle of earth
Answer:
Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.
