A mitochondrion is an organelle that produces energy
Answer:
The correct answer is B.It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment
Explanation:
Hershey and chase in his experiment lebelled the T₂ bacteriophage with radioactive sulfur and radioactive phosphorus separately. Then they infect E.coli with T₂phage and separated phage from bacteria by centrifugation.
Because DNA contains phosphorus not protein, cells infected with phage containing radioactive phosphorous showed radioactivity bacause DNA enters the cell not protein confirming DNA is the genetic material and radioactive sulfur was found in supernatant.

Answer:
B. Mimicry
Explanation:
Mimicry is a method used by several species for their survival and benefit. It literally means to resemble another organism or object. The resemblance can be in looks or in behaviour.
Various kinds of mimicry exist, for example the one used by viceroy butterflies. They resemble monarch butterflies in appearance, i.e. both of them have orange wings with black ridges and they are hard to differentiate from each other. Monarch butterflies are poisonous so predators do not eat them. Since viceroy butterflies look similar to them, they are also confused as them and not consumed. Hence, they are able to protect themselves due to mimicry.
