What happens when a cold front replaces a warm front
frozen [14]

Answer:

When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.

Explanation:

The presence of a cold front means that cold air is advancing and pushing underneath warmer air. This is because the cold air is ‘heavier,’ or denser, than the warm air. Cold air is thus replacing warm air at the surface.

Three species of lizard, labeled A, B, and C, are being studied using molecular analysis by two research colleagues in different
Andreyy89

Answer:

The most appropriate answer would be option B.

The flaw in their reasoning is that they compared different molecules in a different set of organisms.  

For example, they compared the DNA of lizard A and B whereas they compared the RNA of lizard B and C.

In addition, the mutation rates of different molecules (DNA and RNA) are different and thus, comparison of DNA in one set of organism and comparison of RNA in another set cannot be used as the basis for the conclusion.
