Unit 1 Most Missed EOC Review

A group of scientists wanted to test whether or not the breathing rate of fish was affected by the temperature of the water. The data they collected is shown in the table below. What is the dependent variable in the data table?

• temperature
• breathing rate
• fish type
• amount of water

14. A student sets up an experiment with two plants that are each exactly five inches tall. One is given fertilizer and the other is not. After 4 weeks their height is measured again. What is wrong with this experiment?

• Plants naturally grow at different rates. More trials need to be done.
• Plants grow slowly. The time frame is too short.
• There is no control for this experiment.
• The plants need to be taller to get accurate measurements.

A group of scientists wanted to test whether or not the breathing rate of fish was affected by the temperature of the water. The data they collected is shown in the table below. What conclusion can be drawn based on the data provided?

• As the temperature of the water increases, the breathing rate of fish also increases until 30℃ is reached and the breathing rate of fish decreases.
• As the temperature of the water increases, the breathing rate of fish doesn’t change.
• As the temperature of the water increases, the breathing rate of fish decreases.
• As the temperature of the water increases, the breathing rate of fish increases indefinitely.

Krusty Krabs Breath Mints Mr. Krabs created a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich; however, it was just a regular breath mint and did not have a secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties.

Which people are in the control group?

• Group A
• Group B

• the independent variable is distance
• the independent variable is d=25 t
• the dependent variable is time
• the dependent variable is distance
