Tyson wanted to find out if the amount of food given to yellow-bellied sliders would affect
their growth rate. He places the turtles in 3 separate tanks.
• In tank 1, the turtles were fed once a day.
• In tank 2, the turtles were fed twice a day.
• In tank 3, the turtles were fed 3 times a day.
Each feeding consisted of 5 grams of turtle food. The turtle’s weight was recorded daily for 6
weeks. What is the dependent (outcome) variable?

• The turtle's weight

• The amount of time

• The amount of food

• The type of food

Mandy is investigating migration. She thinks that birds instinctively fly south for the winter and hypothesizes that they do so because they cannot survive in cold weather. Which of the following could serve as empirical evidence to support her hypothesis?

• feelings based on her own reactions to winter weather

• data from another scientist’s experiment on bird anatomy

• inferences made about the birds based on observations of flocks of flying geese

As part of her report on the radiation from the sun, Leonora prepared the drawing below to illustrate how wavelengths decrease in the electromagnetic spectrum. However, Leonora made a mistake in the order of her electromagnetic spectrum. What should Leonora do to correct her mistake?

• Place microwaves at the end of the sequence.

• Move ultraviolet so that it comes before infrared.

• Reverse the positions of visible light and infrared.

• Delete visible light because it is not part of the electromagnetic spectrum.

Even if an object does not produce light, it is still visible. Why is this possible?

• the object gives off heat

• the object is large enough to see

• the object absorbs light

• the object reflects light
