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:
a. Maintenance of axons.
Explanation:
Axons are not maintained by microtubules. Microtubules are used in axons as railways to transport different molecules to the terminal branches of the axon or to the soma of the neuron. Axons are maintained by a special type of cells called Schwann cells.
Answer:
The correct answer is D the frequency of O allele is 0.66
Explanation:
The correct answer is D because
A the heterozygote frequency is 0.55.
C the UU genotype frequency is 0.44.
D O allele frequency is 0.66.
E All genotype frequency sums up to 1.
Answer:
The geranium is a vascular plant and has a long life
cycle
Explanation:
Geranium is a species of plant that is genus in the plant kingdom that has several annual and perennial species that are more than 400. Geranium is classified under the subkingdom known as "Tracheobionta", and as such could be referred to as plants that are vascular.
Invariably, geranium which are vascular plants that are often cultivated as horticultural shrubs are long-lived plants, and also have many species that are perennial.
Therefore, we can infer that "the geranium is a vascular plant and has a long life cycle.
