Answer: Valves in the veins

Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.

The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.

Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.

Answer:

B) lighting a match

Explanation:

a chemical change is a chemical reaction involving the rearrangement of atoms. While a physical change can often be reversed, a chemically change typically cannot.

Always remember, if something is being lit on fire then it is a chemical change, since fire breaks the bonds in between the atoms.

Freezing water is a physical change because it can be reversed and does not alter the substance, which is water. a change in state i always a physical change

tearing up a piece of paper is a physical change since nothing on a molecular level has changed. its still paper.

Dissolving sugar in water is a <em>homogenous mixture</em>, meaning that it looks uniform without, however it is still only sugar and water, so it is a physical change.
