Susan wants to see how different chemicals in the soil affect plant growth. therefore, she gets all of the same type of plant, sets them up in the same place, waters them the same amount, but then puts different chemicals on each of them. what is the independent variable in susan's experiment?
the chemicals
the plant growth
the amount of water
where she set-up the plants

The chemicals

Explanation:

When a scientific experiment is proposed, it is necessary that the dependent and independent variables are identified.

An independent variable is one that does not need the influence of another variable and is responsible for presenting a result that depends on its manipulation. The dependent variable, on the other hand, is one that is influenced by the dependent variable and needs its manipulation to generate a result.

In the question above, we saw that Susan wants to know what results the manipulation of different chemicals will have on plant growth. With that, we can say that chemicals are the independent variable, while plant growth is the dependent variable.

answer: c. two haploid cells

explanation:

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
