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.
Answer:
Fractions
Explanation:
1. Write the conversion as a fraction (that equals one)
2. Multiply it out (leaving all units in the answer)
3. Cancel any units that are both top and bottom.
This seems to be a question located online and it quite similar. It comes with a table, from there, you will only have to multiply two values depending on what is given. As for me, 148 is the answer.
The sex cells are called Gametes! Its on Google!
Methamphetamine is neurotoxic to dopaminergic neurons in the human’s midbrain. It increases the amount of the dopamine in the brain and as a result, produces the euphoria feeling that many people experience. It is also indicated that high-dose methamphetamine use can be neurotoxic to serotonin neurons (with the potential of damaging neurons)<span>.</span>
