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.
Evaluating your skills is a key component to a successful physical activity action plan. Assessing yourself through physical tests (e.g. weight and girth measurements) could give you an idea what exactly you want to happen in your training program. Aside from knowing your structure, you should also assess yourself if you are fit enough or you have certain medical conditions that would prohibit you from performing certain activities (e.g. high blood pressure, hypertension).
In doing so, you not only ensure the success of your training action plan, but you also secured your safety before executing the activities you assigned for yourself.
The first answer is true in the sense that these two sports are individual from one another, but it is false in the sense that both these sports are team sports (not just one person is playing).
The second answer is false. For example, if I'm running a 5k without ever having run one before, I'm not sure how long it will take me to finish.
The third answer is true. Swimming is a great exercise that will increase lung capacity and thus improve respiratory health.
The fourth answer is true. A scale will only tell you numbers; it cannot determine what your healthy/comfortable weight is.
The last answer is true. By practicing an activity more, you will become better at it.
The recommended order of exercises is to consider the muscle groups and the kind of exercise you want to participate in, maybe it's challenging or not.
Exercises refer to the active participation in physical activities that can help to improve physical fitness, enhance your health and lower your chance of having heart-related diseases.
While carrying out various types of exercises, the order of groups to be considered are:
- large muscle groups prior to smaller muscle groups
- more challenging exercises before less challenging exercise
Exercise requires you to start slowly with a small amount of time duration and increase the duration of time spent and activities day by day.
