a. radioactive isotopes. They use radioactive Phosphorus-32 as labels on a phage (bacteriophage) DNA that infects E. coli. Their experiment showed that the radioactive isotopes were only seen in E.coli and not in the phage.</span>
Answer:
Their similarity
Explanation:
Pharyngeal pouches are structures in vertebrates that develop in different parts of the body mainly in the face or neck. The similarity in their position and structural indicates a similarity . These structures provide evidence of evolution that the organisms evolved from the same ancestry.
The answer is generation and propagation of action potential.
Na+ channels are important for generation and propagation of action potential. In normal neurons, when neurons hit threshold and action potential is triggered, the Na+ channels open and Na+ ions enter the neuron. After the depolarization of membrane, Na+ channels inactivate. Thus, w<span>ithout Na+ channels, neurons would not be able to depolarize and consequently, the action potential would not be generated.

Answer:
During Francisco Redi's experiment, he showed that when the meat jars were closed, no new organisms appeared. This confirms Spontaneous Generation, the idea that organisms come from one another.
