Biology students designed an experiment to study the effects of temperature on the heartbeat rate of daphnia a small aquatic crustacean. They counted the heartbeat rate at room temperature (25 C). After this each lab group placed test tubes of water containing the same number of daphnia into five beakers containing 150 ml of water. The water temperature of the beakers were 5 C, 10 C, 15 C , 20 C , and one left at 25 C . While waiting 10 minutes, the students placed a microscope slide into each beaker so that the slide would be the same temperature as the daphnia. Students then used a dropper to place daphnia on the slide. While viewing the daphnia through the microscope, the students counted the number of heartbeats for 15 seconds.

8 What is the dependent variable in this experiment

a)

Number of daphnia

b)

Heartbeat rate

c)

Water Temperature

d)

Time in the beaker

e)

None of these are dependent variables in this experiment

Biology students designed an experiment to study the effects of nicotine on the respiration rate of goldfish. They counted the number of times the gills of a goldfish moved at room temperature (25 C). After this each lab group placed two goldfish into five 2000 ml beakers containing 1500 ml of water. They waited 10 minutes for the fish to calm down and begin to breathe normally. The students then used a dropper to place 20, 25, 30 and 35 drops of pure nicotine into the water of four of the beakers. The water in the fifth beaker had no nicotine added to it. While viewing the fish through a magnifying glass the students counted the number of gill movements for 60 seconds.

_____. Which variables in this experiment should made constant in order to get reliable results

Number of fish in each beaker

b)

Amount of water in the beaker

c)

Type of goldfish

d)

Size of the beakers

e)

All of these
