Design a controlled experiment to determine the effect of hot, dry air on head lice. In your experimental design, be sure to: • state the hypothesis to be tested in the experiment [1]
• state one way the control group will be treated differently from the experimental group [1]
• state one result of the experiment that would support the hypothesis [1]

your answer is true

explanation:

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
