In an experiment, a group of scientists want to test the effects of humidity on plant growth. The scientists expose the plants in the study to a range of different humidities to measure plant growth over a specified amount of time. In this experiment. What is the independent variable? Please help me ASAP

A) Plant growth
B) Humidity
С)Fertilizer
D)None of the above

The correct answer is - option B) humidity.

Explanation:

Independent variable is the variable in a scientific experiment that can be modify or change in order to find out the response and analyse the response of dependent variable.

In this experiment the independent variable is humidity as it is changed in order to find out and study plant growth response by the effect of humidity.

Thus, the correct answer is - option B) humidity.

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

is in the form atp or adenosine triphosphate
