False. Adolescents need the same amount of physical activity that adults do. The only thing that varies is the beneficial effects that exercise brings and the overall physical effect it has to the body. Adolescents still have a fast metabolism which enables them to maintain their shape despite the amount of caloric intakes they've had while adults don't. Exercise duration should at least last for 30 minutes to induce physical fitness in the body and this works for young adults and mature adults alike.
Answer:
B. The findings are not meaningful or valid because of the way she designed her study.
Explanation:
In a scientific experiment, a control group is a group of individuals/subjects that do not receive the experimental treatment. The control group is used to determine how much of an impact a treatment (in this case, cadmium intake) has on the variables being examined in the participants who are subjected to the experimental treatment. In any experiment, it is imperative to include a control group in order to validate experimental results. In this case, it is not possible to confirm that the loss of weight and abnormal hormone levels are due to cadmium uptake because only a control group would elucidate the contribution of cadmium intake on the variables being tested.
The answer is either agility or coordination I believe
