A student designed an experiment to test the environmental preferences of pill bugs (roly-polies). The student wanted to test if pill bugs prefer a salty environment or not. To perform this
experiment he lined the bottom of one side of a choice chamber with a paper towel soaked in 1%
salt solution, and on the other side of the choice chamber he lined the bottom with a paper towel
soaked in 0% salt water. He then placed 5 pill bugs on either side of the choice chamber and
recorded the number of pill bugs on either side of the chamber every minute for 10 minutes.
What is the control group in the experiment described above?

good luck

explanation:

i still can't find this

the answer would be d

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answer; i believe that the correct answer to this statement is (exoticism); //

exoticism was a trend where musicians created music based on a far off foreign
