If you want to selectively label RNA being synthesized by cells(and not DNA) what radioactive compound would you add to the medi

romanna [79]

The right answer is E.

Uracil is a nitrogenous base (pyrimidine) specific for RNA. The nucleoide of uracil is called uridine and nucleotide is called uridine monophosphate or uridylate. In the DNA, there is thymine instead of uracil.

So if we mark the uracils, only the RNA will be marked. The DNA will not be given that there is no uracil in it.

faltersainse [42]

The thorax is a very vital and important organ in the human body.

It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.c

It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases.

When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases.

Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law.

Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.

Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

tester [92]

Answer:

1. Are usually single-celled.

2. Do not contain membrane-bound organelles

3. Have DNA located in cytoplasm

Explanation:

Prokaryotic cells are single-celled organisms which have the following characters:

1. They lack a true nucleus and hence, they do not have their genetic material enclosed in a nuclear membrane-bound nucleus, rather it is present in the cytoplasm.

2. They lack all the membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.

3. They are usually. very small in size and hence are microscopic.

Examples include all the bacterias.
