Most proteins in cells are functional at the tertiary level of structure.

The sodium-potassium pump moves ions down their concentration gradient (high to low).

A scientist wants to test whether the amount of sunlight affects the growth of tomato plants. They grows three groups of plants: one with full sunlight, one with partial sunlight, and one kept in the shade. All plants are given the same amount of water, soil type, and fertilizer. After 4 weeks, they measures the height of the plants. Which of the following correctly identifies the variables?

Informative and persuasive speeches overlap in their purpose and approach.

Entertaining speeches always end with a call to action.
