25.
Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music.
Which component is missing from Carmen’s experiment?
Which component is missing from Carmen’s experiment?
a)
a question
b)
a hypothesis
c)
a control group
d)
a description of the experiment
26.

Which statement describes how photosynthesis and cellular respiration are interrelated?
Which statement describes how photosynthesis and cellular respiration are interrelated?
a)
Oxygen is produced during cellular respiration and stored during photosynthesis.
b)
Carbon dioxide and water released by cellular respiration are used in photosynthesis.
c)
Photosynthesis releases the energy that is stored during the process of cellular respiration.
d)
Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.
27.
Which gas is removed from the atmosphere during photosynthesis?
a)
hydrogen
b)

c)
nitrogen
d)

28.
Why are there less air bubbles as the plant is place further away from the light source
a)
