Animal cells are prokaryotic and Plant cells are eukaryotic* are true the others are false
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.
We know that the word equation for the reaction taking place during photosynthesis is:
carbon dioxide + water + sunlight → glucose + oxygen
Therefore, the more the reactants are provided, the more the plant will grow. The lesser the reactants, the lesser the growth. Providing products will not alter the rate of photosynthesis. The factors may be grouped as:
Increase plant growth:
-increase sunlight
-increase carbon dioxide
-increase water
No effect on plant growth:
-increase glucose
-increase oxygen
-decrease glucose
-decrease oxygen
Decrease plant growth:
-decrease water
-decrease sunlight
-decrease carbon dioxide
Heterogeneous mixture
Explanation:
A heterogeneous mixture is a mixture that has different properties throughout its composition. These are mixtures that exists in at least two different phases.
Based on their phases, they are divided into;
- Gas - liquid mixtures for example aerated drinks
- Liquid - solid mixtures for example muddy water
- Gas solid mixtures for example solid particles in air
Mixtures are impure substances with usually indefinite composition.

cAMP is the second messenger in the pathway.
cAMP or Cyclic AMP is a secondary messenger because it transmits signals from a receptor to a target cell. When the level increases rapidly, it starts following receptor-mediated activation of AC (adenylyl cyclase), and that catalyzes the conversion of AMP (adenosine monophosphate) to cAMP.
The cAMP pathway is also known as the adenylyl cyclase pathway, which is a G protein-coupled receptor that is used in the cell signaling process. It works by activating protein kinase A. Therefore, cAMP is considered a secondary messenger which also regulates various cellular functions like cell growth, cell differentiation, etc.
