Answer:

Semi-conservative

Explanation:

Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).

Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.

Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.

Guess what? they show both! (See the image for more information)

What part of the peripheral nervous system prevent you from holding your breath

artcher [175]

Answer:

The respiratory centers that control your rate of breathing are in the brainstem or medulla. The nerve cells that live within these centers automatically send signals to the diaphragm and intercostal muscles to contract and relax at regular intervals.
