Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea. She placed a piece of Elodea in a beaker of water and set the beaker 10 centimeters (cm) from a light source. Keesha counted the bubbles released from the plant every minute for five minutes (min). She repeated the process two more times. First, she moved the light to 20 cm from the beaker, and then she moved the light to 30 cm from the beaker. Keesha’s setup and data are shown below. What is the outcome variable (dependent variable) in this experiment?
the number of bubbles produced
the type of plant placed in the beaker
the amount of time the bubbles were counted
the distance of the light source from the plant

Mangrove trees are common to the Florida Everglades. The tree roots serve as a place for freshwater oysters to attach when the tide is high, as shown in the picture below. The oysters are protected from predators when attached to the roots underwater. The oysters do not harm the trees nor do they provide any benefit to the trees. Which of the following relationships is most similar to the relationship between the mangrove trees and the oysters?
African ants living in acacia trees feed on leaf-eating insects found on the tree.
Spider crabs are camouflaged by the green-brown algae growing on their shells.
A whale is unaffected by the attached remora fish feeding on the whale’s leftover food.
Bees fly from one flowering plant to another gathering nectar and pollinating the flowers.
