You are curious about the effects of different watering schedules on your favorite fruit, strawberries. You set up plants, all the same age and size, and plant them in identical pots with the same potting soil. You water them once a week, every day, or every other day. Every day, you check the plants for strawberries, and record the number and size of the berries produced by each plant.

The complete question is as follows:

What is the independent variable in this strawberry experiment?

O the type of pots

O the number and weight of strawberries produced

the potting soil

O the water schedule

O size and age of plants

The correct answer is - the watering schedule.

Explanation:

Independent variable is the variable or the factor which is changed or manipulated during a study or experiment to find the effect on the dependent variable.

The variable that is manipulated in this experiment is the watering schedule and the aim of the experiment is also finding the role of the effect of the watering schedule on fruit production. In this study, the watering schedule is manipulated for different pots of plants to see the effect on the production of fruit.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
