each of the plants should be planted with different types of soil.

both plants should receive the same amount of sunlight each day.

each of the plants should be planted with different types of fertilizer.

1 plant should receive sunlight each day, and 1 plant should never receive sunlight.

Greetings!

The correct answer choice is Choice 4.

Why?

In a scientific experiment the only thing being changed is the independent variable. Everything else should stay the same.

In this experiment, the independent variable is the amount of sunlight each plant should receive. Here's a tip- when looking for and independent variable look for whats being changed on purpose.

Hope this helps!

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
