Answer:
The correct answer is option e. "None of the above".
Explanation:
The Hershey-Chase experiment helped to prove that DNA was the genetic material, by specifically labeling the DNA material of a bacteriophage with phosphorus-32. In this experiment the lambda phage is labeled with heavy and light Cl. CI-36, the one that is heavy and radioactive, corresponds to Chlorine-36. Chlorine is not an element found in DNA such as phosphorus, therefore lambda DNA will not be labeled and no radioactivity will be detected.
<span>As blood moves away from the heart toward the tissues, the relative size of blood vessels decreases, the blood pressure drops, and the velocity of blood flow slows.
The size of the arteries progressively decreases as they branch out from the major arteries of the body. Once the arteries are the size of the arterioles, the resistance to blood flow increases and velocity of blood flow slows then blood pressure drops.

Answer:
Prokaryotes.
Explanation:
Most of the Eukaryotes most likely to evolve from the Prokaryotes. Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside the plasma membrane, which is a thin layer of lipid that completely surrounds the cell. Prokaryotes reproduce by binary fission method.
The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.
- The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
- With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
- All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
- While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.

This is true. when it is warmer the planet and insects can migrate to thses other places so they do not have to die or hibernate through winter.
