According to this simplified water cycle, the process of transpiration is the process that -

• speeds the evaporation of water

• releases water vapor from plants

• causes photosynthesis in plants

• increases the rate of the water cycle

The organisms at the beginning of a food chain are -

• decomposers

• consumers

• omnivores

• producers

When there is a lower concentration of water outside of a plant cell rather than inside a plant cell, the plant will tend to -

• increase its rate of photosynthesis

• lose water and wilt

• gain water and become rigid

• grow toward the sun

Some insects can stand on the surface of water because water -

• is a good evaporative coolant

• is cohesive and adhesive

• has a high boiling point

• has a high specific heat

As a result of the above experiment, responses of a planarian to different environmental stimuli were recorded. Planaria seem to have the strongest response to -

• sound

• light

• magnetism

• gravity

Which of these functions most like the "brain" of a cell?

• golgi apparatus

• mitochondrion

• nucleus

• smooth endoplasmic reticulum

Many Northern Hemisphere birds respond to seasonal environmental changes by -

• mutating

• hibernating

• estivating

• migrating

"I took a good clear piece of Cork and with a Pen-Knife sharpen'd as keen as a razor . . . cut off . . . an exceeding thin piece of it. For upon examination with my Microscope, I could exceedingly plainly perceive it to be all perforated and porous . . . These pores, or cells, were not very deep, but consisted of a great many little Boxes."

These words were written by Robert Hooke in 1665. The pores or cells that Hooke described were really -

• nuclei

• cell membranes

• mitochondria

• cell walls

Cells from which of the following organisms would be expected to contain cell walls?

• sponge

• water lily

• paramecium

• cricket

Which of the following macromolecules are a prominent part of animal tissues that function in insulation, helping animals conserve heat?

• nucleic acids

• lipids

• carbohydrates

• proteins
