You've been growing numerous plants in a greenhouse in dishes called flats. Different flats have different number of plant speci

es in them (ranging from 1, 2, 4, and 8). You've grown these plants for 6 weeks and finally examining them.
Suppose you changed this lab's experimental design. Which of the following changes would probably NOT change the results?

a. Substituting slow-growing lettuces for rutabaga and mustard.
b. Letting the plants grow for twice as long, so some of the "fast-starters" slow down growth and "slow-starters" speed up.
c. Restricting water and/or nutrients, instead of supplying ample quantities of both.
d. Adding leaf-eating caterpillars that prefer rutabaga.
e. Moving the trays farther apart in the greenhouse, so the edges don't touch one another.

I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.

Shalnov [3]
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

What solution describes a saturated solution?
WITCHER [35]

Answer:

This is not my answer, I found it on the internet.

No more solutes can be dissolved in a saturated solution at a given temperature and pressure.

Explanation:

A saturated solution is a solution that consists of maximum amount and concentration of the solute that is dissolved in the solvent.

The extra amount of solute cannot be dissolved in a saturated solution.

The saturated solution is composed of solute and solvent and solvent cannot dissolve more solute at some extent.

The carbonated beverage is an ideal example of saturated solution.
