Match the functional groups with their structures:
evablogger [386]
The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️

Zarrin [17]

Answer:

EXERCISE

Explanation:

In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.

In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).

The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
