1. from the graph below, what is the carrying capacity?

a. 1.6

Explanation:

• Question 17: In an experiment, the dependent variable is what is measured. The independent variable is manipulated, the controlled variable is kept the same, and a constant variable is unchanged.
• Question 18: Group A (ate chocolate) produced 5000 stacks, Group B (no chocolate) produced 6500 stacks. Since 5000 < 6500, chocolate didn't increase productivity.
• Question 19: The number of stacks (5000 and 6500) is data collected (dependent variable as it depends on chocolate - eating status).
• Question 20: Carrying capacity is the maximum population size an environment can sustain. From the graph, it fluctuates around 1.6 million.

Answer:

• 17. A. dependent variable
• 18. A. The chocolate doesn't work.
• 19. B. dependent variable; D. Data
• 20. A. 1.6
