An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

(HINT: Dependent is what you measure, Independent is what you are testing)

• The type of plant
• The amount of sunlight
• The type of music
• The type of liquid

A tapeworm and a cat have this type of relationship. (tape worms harm the cat)

• mutualism
• parasitism
• commensalism

These diagrams show a variety of cells from the same organism.

How can cells from the same organism have such different shapes and functions?As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.

• As each cell differentiates, the DNA changes so that each type of cell has different

• Mutations in the cells’ nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

• During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

• During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.
