Have your ideas about what happens to molecules in the liquid, solid, and gas phase changed? If so, how? What evidence supports
Westkost [7]

Various states of matter have molecules moving at different velocities.

<h3>Molecules in matter</h3>

Matter is composed of molecules. These molecules that compose matter are in constant random motion. The kinetic energy and velocity of the molecules depends on the state of matter.

Molecules of a gas are fastest followed by molecules in a liquid. Molecules in a solid do not move at all hence solids have a definite shape.

PLZ HELP ME Question 3
Flauer [41]

Answer:

It's impossible to predict the phenotype of the offspring by only observing the parents because DNA from their grandparents can affect the offspring as well.

Explanation:

DNA is combined from the parents to create offspring. When that offspring reproduces their children not only possess DNA from their parents but from their grandparents as well. Mixing together two separate DNA's from two different family trees can result in rare genetic mutations which results in the offspring looking different from their parents but showing resemblance to their grandparents. This is why you have to look at the phenotypes of more then just the two parents because there are more possibilities, including what their grandparents looked like.
