One independentvariables can be tested in a controlled experiment. The correct option is A.
A person, place, thing, or phenomenon that you are attempting to quantify in any way is simply referred to as a variable in research.
The best approach to distinguish between a dependent and independent variable is to look at what the words themselves reveal about the variable you're using.
Only one variable at a time should be tested in an experiment. This guarantees that the experimental result is definitely caused by a single, recognisable component.
A controlled experiment in a scientific study is a test that the researcher actively modifies such that only onevariable is examined at a time.
Thus, the correct option is A.

Answer:
DNA (deoxyribonucleic acid)
Explanation:
In living beings (and in retroviruses), the genetic material is composed almost exclusively of deoxyribonucleic acid, known as double-stranded DNA.
DNA is an organic compound that contains genetic information that coordinates the development and the vital functions of the organisms of living beings.
That means that it determines the physical and physiological characteristics. In addition, it has the function of transmitting hereditary traits, such as, for example, hair color, eye color, and much other physical aspects.
In the case of DNA viruses, the material may be made of single-stranded DNA, while RNA viruses have RNAribonucleic acid as their genetic material.

Answer:
The Great Plains
Explanation:
Hot air has a much lower density than cold air and for this reason, the large plains would be ideal for an industrial city if the goal is to have fewer air pollution incidents related to temperature inversions. This is because if the large plains are lower, soon the hot air will rise while the cold air will tend to go down.
In short, within the great plains the hot air being less dense rises, in contrast, the cold air (more dense) descends, forming the convection currents.
Answer:
See explanation.
Explanation:
In a chemical reaction, the substances change. Put hydrogen and oxygen together and the chemical reaction results in water.
A physical reaction there is a change in form, but the chemical composition remains the same. Take water below freezing, and ice forms - a physical reaction.
Answer:
Explanation:
In a chemical reaction, the substances change all together and there is no going back you cant take them apart.
A physical reaction there is a changes, but the chemical composition dosnt. this one you can go back from it becuse the chemical reaction didnt change.
