Which best explains why muscle cells are different from blood cells?
A mutation occurs during the development of muscle cells but not in blood cells.
Different genes are activated in muscle cells than in blood cells.
Muscles cells experience different environmental influences than blood cells.
Muscle cells are produced by the brain, but blood cells are produced by the heart.
During which phase of the cell cycle is the cell growing and preparing for cellular division?
cytokinesis

The yucca plant releases a strong scent at night when the yucca moth is active. The yucca moth, attracted by the scent, gathers pollen from the yucca flower. The yucca moth then deposits her eggs and the pollen on another plant. This ensures that the plant will be cross-pollinated and that the yucca moth larvae have a steady food supply. Which relationship does this best illustrate?
commensalism
mutualism
parasitism
predation
Some marine worms and mollusks go through similar larval stages during development. Which can be inferred about their relationship?
They share a common ancestor
The mate with each other
They compete for a habitat
The share the same food source
Which statement best describes natural selection?
As the weather changes, organisms that are able to find shelter need less energy to live.
Organisms that eat only plants need less food than organisms that eat animals.
Organisms better adapted to their environment are more likely to reproduce and pass on their traits to their offspring.
Small organisms are more likely to survive than larger organisms.
Which word equation best represents the process of cellular respiration?
carbon dioxide + glucose → oxygen + water
carbon dioxide + water → glucose + oxygen
glucose + oxygen → carbon dioxide + water
oxygen + water → carbon dioxide + glucose
A contractile vacuole helps protists eliminate excess liquid. This is a "pumping" process which reduces pressure inside the cell and prevents the cell from bursting. What is most likely the source of energy for this process?
DNA
lipids
ATP
ribosomes
What would happen if the population of zebras decreased?
There would be less grass for other animals.
Populations of lions & hyenas would decrease.
Termites would have no food.
Baboons would have more competition for food.
