When a particular species begins to overpopulate, what might cause the species to begin to die out?

• The organisms may not be able to find a mate.

• The organisms may mutate to adapt to the overpopulation.

• The organisms compete more for nutrients and begin to die when their food source has been consumed.

• Overpopulation has a positive effect on the population so their numbers would increase.

How might plants adapt to get more sunlight?

• Vines wrap around a tree

• Grow in the forest canopy

• Grow floating on the top of the water

• All of the above

If objects are moving in the same direction...

• The forces are balanced, the net force is zero.

• The forces are unbalanced.

• The forces are equal and unbalanced.

If environmental changes interfere with photosynthesis...

• The organisms will grow larger than usual.

• The plants will increase in size but decrease in number.

• The plant population would be reduced.

Which types of organisms have cells with very large vacuoles?

• Animals

• Fungi

• Plants

• Bacteria

What is the function of the vacuole?

• stores water

• produces sugar

• converts energy

• regulates cell contents

What is the function of the chloroplasts?

• stores water

• produces sugar

• converts energy

• regulates cell contents

What is the function of the cell membrane?

• stores water

• produces sugar

• converts energy

• regulates cell contents

What is the function of the mitochondrion?

• stores water

• produces sugar

• converts energy

• regulates cell contents

When does a object have more potential energy?

• When it is in a higher position sitting still.

• When it is in a lower position, because it moved.
