Questions and Answers

What is the next step in the scientific method after rejecting or failing to reject hypotheses?

  • Draw conclusions
  • Develop new hypotheses
  • Refine hypothesis and repeat (correct)
  • Publish results

In a scientific experiment, what is the purpose of having a treatment group and a control group?

  • To ensure no changes occur during the experiment
  • To compare the effects of the manipulated variable (correct)
  • To keep all variables constant
  • To introduce randomness into the experiment

In the context of kin selection, why is relatedness asymmetry important for determining social behavior?

  • It leads to competition within families
  • It promotes genetic mutations
  • It influences how individuals help their closest relatives (correct)
  • It ensures equal distribution of resources
