The structure of DNA contains specific sequences of 4 nitrogenous bases, whose extension constitutes the coded genetic information. A chromosome is formed by a DNA molecule, and the genes contained in the chromosome locus are sequences of nucleotides coming from fragments of that same DNA.

All the genetic information —DNA, chromosomes and genes— is located in the cell nucleus.

You perform an experiment on two plants of the same species to find out what soil affects their growth the most. Both plants are

Nezavi [6.7K]

Answer:

Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water

Explanation:

First we should define what the variables in the experiment are.

Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.

Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.

Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.

In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;

Independent Variable - The Soil
Dependent Variable - The Height Of The Plant
Control Variable - The Amount of Water and Sun Exposure

I hope this answer helps.
