it requires energy
it moves substances down in
concentration
it does not require energy

concentration
8 multiple choice 1 point
which of the following is not an example of
quantitative data?
number of flowers on a plant
height of a flower
amount of seeds on a flower
color of a flower

Explanation:

Question 7

Active transport is a process in cells where substances are moved against their concentration gradient (from low to high concentration). This process requires energy (usually from ATP). The other options describe passive transport (movement down concentration gradient, no energy needed, high to low concentration movement). So the correct statement about active transport is that it requires energy.

Quantitative data is numerical and measurable. The number of flowers, height of a flower, and amount of seeds are all numerical values (can be counted or measured). The color of a flower is a qualitative characteristic (descriptive, non - numerical), so it is not an example of quantitative data.

Answer:

A. it requires energy
