Select all the correct answers. Regina is testing this hypothesis:
Higher relative humidity leads to faster growth in orchids.

She has designed an experiment in which she will grow orchids in terrariums of varying humidity levels. She will then observe how the humidity affects the growth of the plants.

Which of the following variables are the confounding variables that Regina should control for before beginning her experiment?

1.the amount of sunlight the plants receive

2.the temperature at which the plants grow

3.the type of soil in which the plants grow

4.the growth rate of each of the plants

5.the relative humidity inside each terrarium

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
