As matter changes state from solid to liquid, what statement can we make about the attractive force between its molecules?
a) it decreases.
b) it increases.
c) it remains constant.
d) it varies depending on location.

The correct option is A.

Explanation:

In solid state, the atoms are tightly packed due to the strong force of attraction between its molecules.

In liquid state, the atoms are not tightly packed due to the less force of attraction between its molecules as compared in solid state.

In the given problem, matter changes state from solid to liquid then the force of attraction between its molecules decreases.

Therefore, the correct option is A.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
