Debra says that there is no gravitational force between dust particles because they have insignificant mass. Peggy says that dust particles do pull on each other gravitationally and would move toward each other if they were in outer space. Who has the better argument and why?
A. Debra, because the objects with only a little mass are not affected by gravity
B. Debra, because any force on a dust particle would change its motion.
C. Peggy, because any two objects exert a gravitational force on each other.
D. Peggy because objects with smaller mass have more gravity acting on them

As a bee feeds upon the nectar produced by a flower, the bee may become coated with the flower's pollen. As the bee flies from flower to flower, some of this pollen may contact a flower's pistil, resulting in pollination. Which of the following is the relationship between the bee and the flower?
A. competition
B. commensalism
C. mutualism
D. parasitism

You and your classmate are discussing different organs and organ systems within the human body. Your friend states that the excretory system includes multiple organs, and one of those organs is the lungs. You argue that the lungs can’t possibly be in the excretory system since it is part of the respiratory system. Which of the following choices would be the best statement that your friend would use to justify why the lungs help keep homeostasis for the excretory system?
A. The lungs bring in oxygen, which is a vital gas to keep our cells alive and healthy.
B. The lungs exhale carbon dioxide, which is a waste gas and needs to be removed from the body.
C. The lungs provide cells with a gas that is important for the cell process of respiration.
D. The lungs remove waste in the forms of solids, liquids, and gases that could be harmful for the body.
