The dark spot in each of these cells contains genetic material called DNA. This part of the cell is called the:
-
Vacuole
No. A vacuole is used for storing water or nutrients, not DNA. -
Nucleus
Yes! The nucleus of the cell contains DNA. -
Chloroplast
No. Chloroplasts contain chlorophyll, which is used in photosynthesis. -
Ribosome
No. Ribosomes are parts of the cell that assemble proteins.

Which of the following is NOT a characteristic of ALL mammals?
-
All mammals have hair.
No. All mammals DO have hair. Even whales and dolphins have some hair on their skin. -
All mammals give birth to live young.
Yes! While most species of mammals give birth to live young, a few (platypus, echidna) lay eggs. -
All mammals have mammary glands.
No. All mammals DO have mammary glands. In females, these glands can produce milk to feed their young. -
All mammals have three bones in their inner ear.
No. All mammals DO have three bones in their inner ear. These bones are called the malleus, the incus, and the stapes. They transfer vibration from the ear drum to the inner ear.

You have probably seen patterns of light like this in a pool of water. What causes it?
-
Absorption
No. If the light was being absorbed, the pattern would be dark instead of bright. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the entire area brighter, not a specific pattern. -
Reflection
No. While the light has to reflect back to your eye for you to see it, reflection does not cause this pattern. -
Refraction
Yes! Refraction bends light. Waves and ripples on the surface of the water act just like the curved surface of a lens. This bends the light into patterns that have shapes similar to the ripples on the water's surface.

This is a lichen, which is actually a fungus and an algae living together. As it grows, it produces chemicals which dissolve some of the rock it grows on. This is an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The lichen is dissolving the rock, but not carrying it away. -
Weathering
Yes! Lichens cause quite a bit of weathering in rocky areas. -
Both erosion and weathering
No. The rock is not being moved, so it is not erosion. -
Neither erosion nor weathering
No. As the lichen dissolves the rock, that is an example of weathering.

When this cannon fires, cannon and the cannon ball both move, but the cannon ball moves much farther and faster than the cannon. Why?
-
The cannon ball is smaller.
No. While smaller size means a little less air resistance, that is not enough to cause the difference. -
The wheels on the cannon are stuck.
No. Even with the wheels moving freely, the cannon ball will still move much faster and much farther. -
The cannon ball is round.
No. While the round shape means a little less air resistance, that is not enough to cause the difference. -
The cannon ball weighs less.
Yes! According to Newton's Second Law of Motion, the more mass an object has, the less it will be affected by a force. Newton's Third Law of Motion tells us that the cannon and the cannon ball will both be pushed by the same amount of force, but since the cannon is much heavier (more mass), it will not move as fast or as far.If the cannon was made of very light weight plastic, so that it was much ligher (less mass) than the cannon ball, then the cannon would move farther and faster.
