What would be growing on a piece of apple that is brown and fuzzy?
Mold is sometimes brown and fuzzy.

Is the flu caused by bacteria or virus?
Virus.

What does light do when it hits water?
It is refracted.
200
Which would have the higher pitch when the glass is tapped - the glass with much water, or the glass with not so much water?
Higher pitch would be from the glass with less water. The more water, the lower the pitch. Water's like fat, like thickness; the more there is, the slower the vibration, the lower the pitch.

What can many protozoa do that most fungi cannot do?
Move by themselves.

Nope. We get light from the sun.
500
How would you lower the pitch of a drum?
Loosen the skin.
500
If you had a jar, half of which was covered, would you expect to find Euglena on the light half or the dark half?
Light half. They have an eye spot - go toward the light.

What does mold need to grow?
Food and moisture - that's why it grows on bread. Bread is the food. That's also why dry stuff doesn't grow mold.
