During a lab experiment a student took his resting pulse rate, counting 23 beats in 20 seconds. The student then exercised for several minutes. The student’s pulse was taken immediately after the exercise, and then every minute for 6 minutes. The graph below shows changes in the pulse rate after the exercise was completed.
What was the student’s resting pulse rate in beats per minute?

Base your answer to the following question on the information and diagram below and on our knowledge of biology.
Two test tubes, A and B, were set up as shown in the diagram below. Bromthymol blue, which turns from blue to yellow in the presence of carbon dioxide, was added to the water at the bottom of each tube before the tubes were sealed. The tubes were maintained at the temperature shown for six days. (Average room temperature is 20 degrees Celsius).
Identify the life process responsible for the change intube A.

Single-celled organisms are able to maintain homeostasis, even though they lack higher levels of organization such as organs and organ systems, because:
multicellular organisms do not rely on tissues or organs to carry out life processes
single-celled organisms do not carry out the same life processes as multicellular organisms
cell structures work together to maintain homeostasis in single-celled organisms
single-celled organisms are able to coordinate organ functions to maintain homeostasis
What is the purpose of antigens?
To stimulate an immune response and produce antibodies
To store nutrients
To control heart rate
To transport oxygen
Infections are always accompanied by symptoms such as fever and fatigue.
