Answer:

B. Explanations are based on observations, evidence, and testing.

Explanation:

The scientific method has five basic steps plus one feedback step:

  • Make a note.
  • Ask a question.
  • Formulate a hypothesis or a testable explanation.
  • Make a prediction based on the hypothesis.
  • Test the forecast.
  • Repeat: Use the results to formulate new hypotheses or predictions.

The scientific method is used in all sciences. Scientists in these fields ask other questions and perform other tests. However, they use the same approach to find the answers that are logical and supported by evidence.

dezoksy [38]

Answer:

The electrons produced via this process is accepted by NAD+ to yield NADH.

The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).

Sindrei [870]

Answer:

C. -independent, dependent, intervening

Explanation:

Independent variable is defined as the variable that can be changed during the experiment, dependent variable is the variable which is being tested and whose value depends on independent variable and intervening variable impacts the relationship between a dependent variable and an independent.

So, in the given study, ice cream was an independent variable as it can be changed during study and Howard wants to study its impact, fighting was a dependent variable as it is being tested and the temperature was the intervening variable as it is a cause of independent variable and also impacts the relationship between a dependent variable and an independent.

Hence, the correct option is C. independent, dependent, intervening.
