Which of the following best describes the dependent variable in an experiment?
A- the variable that is measured
B- the variable that is manipulated
C- the variable that you can see
D- the variable that is most common
(My guess is A)
Photosynthesis is the process whereby plants transform light energy from the sun into chemical energy. What is the molecule called that stores this chemical energy?
A- glucose
B- water
C- carbon
D- nitrogen
(My guess is A)
yes, yes
For the first question, your guess is correct. The dependent variable in an experiment is the variable that is measured. So, option A is the best description of the dependent variable.
For the second question, your guess is also correct. The molecule that stores the chemical energy produced during photosynthesis is glucose. So, option A is the correct answer.
For the first question, the dependent variable in an experiment is the variable that is measured. It is the variable that is expected to change in response to the manipulation of the independent variable.
To determine the answer to the first question, you would need to understand the basic concept of independent and dependent variables in experiments. The independent variable is the variable that is deliberately manipulated or changed by the researcher. On the other hand, the dependent variable is the variable that is observed or measured to determine the effect of the independent variable.
In this case, as you rightly guessed, the dependent variable in an experiment would be A- the variable that is measured.
For the second question, the molecule that stores the chemical energy generated by photosynthesis is glucose. During photosynthesis, plants convert light energy into chemical energy in the form of glucose.
To find the answer to the second question, you need to have a basic understanding of the process of photosynthesis and the products it generates. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Glucose is the primary molecule that stores this chemical energy, which is subsequently utilized by the plant for growth and other metabolic processes.
Therefore, your answer is A- glucose.
