Scientists studying a certain species of bacteria hypothesize that these bacteria use active transport to take in sugar. Which of the following best supports this hypothesis?

• Sugar intake rate increases as the use of ATP increases.

• Sugar intake rate increases as the temperature increases.

• Sugar intake rate increases as the number of ribosomes inside the bacteria increases.

• Sugar intake rate increases as the concentration of sugar outside the bacteria increases.

The graph shows the amount of product produced in an enzyme-controlled reaction at different pH levels.  What is a valid conclusion that can be made from this data?

• All enzymes work best at a pH of 7.

• This reaction occurs mostly in acidic environments.

• The optimum environment for this enzyme has a neutral pH.

• No enzymes are able to work on substrates in basic environments.

Both euglena and cyanobacteria are photosynthetic unicellular organisms found in pond water. The feature that distinguishes euglena from cyanobacteria is the —

• ability to maintain homeostasis

• presence of ribosomes

• ability to reproduce

• presence of a nuclear membrane

In an experiment to determine the effect of exercise on cellular respiration.  Students participated in the same aerobic exercise for 1 minute, 3 minutes, 5 minutes, and 7 minutes.  After each exercise interval, students blew into a respirometer, a device that measures gasses. The experiment was repeated each day for 2 weeks.  What is the dependent variable that is being measured in this experiment?

• The amount of sugar produced by the students.

• The amount of oxygen produced by the students

• The amount of exercise completed by the students

• The amount of carbon dioxide produced by the students.

  The amount of carbon dioxide produced by the students.
