*10 points!* A scientist wants to know if fertilizer helps plants grow faster. She adds fertilizer to 50 plants regular soil. She keeps 50 plants in the same regular soil. She predicts that those receiving fertilizer will grow faster. They are plant in the type of container, temperature, and water amount. She carries the experiment for 10 months. Using the above information identify the following:
1. Hypothesis
2. Control group
3. Experimental group
4. Independent Variable
5. Dependent Variable
6. Constants
7. What can be done to improve the validity of the experiment

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: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.  

hope its .

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
