Astudent conducts an experiment to see how music affects plant growth. the student obtains four identical plants. each one is potted in the same type of soil and receives the same amount of sunlight and water each day. plant a listens to classical music for three hours each day. plant b listens to rock music for three hours each day. plant c listens to country music for three hours each day. plant d does not listen to any music at all.
1. in the experiment described in the scenario, what's the variable?

a. the amount of water each plant receives
b. the amount of sunlight each plant receives
c. the type of soil in which each plant is potted
d. the type of music each plant listens to

D. The type of music each plant listens to

Explanation:

The question indicates each plant is in the same soil (so cannot be C), received the same amount of sunlight (so cannot be B) and the same amount of water (cannot be A).

However, each plant is exposed to a different type of music, one is listening classical,  another rock  and another country music.

So, the only variable in here is the type of music each plant listens to.

b - the respond is innate and varies over time.

good luck!

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
