In order to maintain homeostasis, it is most important for an animal to be able to — 

• increase its prey population
• change its habitat
• respond to its environment
• hide from its predators

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

• grow toward the sun
• lose water and wilt
• gain water and become rigid
• increase its rate of photosynthesis

The concentration of glucose must be maintained within a fairly narrow range in most vertebrates. This statement is an example of —

• homeostasis
• excretion
• fermentation
• glycolysis

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

• has a high boiling point
• is a good evaporative coolant
• is cohesive and adhesive
• has a high specific heat

 In the human body, muscle cells have an increased need for energy during exercise. To help supply this energy, the body will immediately increase —

• activity in the nervous system to stimulate intake of carbon dioxide
• the need for waste products to be retained
• the breathing rate to supply more oxygen to cells for the release of energy
• food intake to increase the substances available for respiration

Some peeled pieces of apple were placed in distilled water and some in very salty water. The cells in the apple pieces will —

• gain water in the distilled water and lose water in the salty water
• lose water in both solutions
• gain water in both solutions
• lose water in the distilled water and gain water in the salty water

If transpiration stopped completely, how would a plant’s homeostasis first be affected?

• Water molecules would not be released from leaves.
• More carbon dioxide molecules would be taken in by leaves.
• Fewer sugars stored in roots and stems would diffuse into the soil.
• Carbohydrates would no longer be formed.

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

• causes photosynthesis in plants
• increases the rate of the water cycle
• speeds the evaporation of water
• releases water vapor from plants

 Which of the following molecules is most abundant in the cells of the human body?

• water
• amino acids
• nucleotides
• lipids

Unlike other animals, mammals can perspire. The main benefit of perspiring is that it — 

• relaxes the muscles
• cools the skin with evaporation
• removes extra water from the cells
• removes dirt from the surface of the skin
