Answer:
This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?
Independent variable: ORGANIC AND CHEMICAL FERTILIZERS
Dependent variable: HEIGHT OF PLANT
Controlled variable: Same type of seed, water
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.
Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.
Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.
Yeah sure what do u need help with
Answer:
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes

Hope this helped <3
I would say A. Quantitative data involves numbers and stuff like that. Unlike qualitative data, which involves pictures and not numerical data. I hope this helped.
Answer:
Codon are nucleotide triplets (DNA or RNA)
So the answer is a three-based code
