Answer:
The skeletal system provides support and structure to the body and serves to protect vital organs, such as your brain, heart and lungs. Working with muscles, the skeletal system assists in movement. While bones are hard, they can be broken and weakened if not cared for properly. A good diet and regular exercise will help keep your skeletal system strong and healthy.Eat calcium-rich foods. The American Academy of Orthopedic Surgeons recommends that men and women get at least 1,000 mg of calcium each day. This is especially true for people over age 40, when natural bone replacement slows down. Milk, cheese and other dairy products contain calcium. Broccoli, kale, sardines, salmon, Brazil nuts, almonds, oranges and calcium-fortified foods are good sources of calcium as well. The American Academy of Orthopedic Surgeons indicates that getting 1,000 mg of calcium through diet alone may be difficult and therefore suggests a vitamin supplement as well.

Answer:
a. internal
Explanation:
This experiment results show that the drug effect on patients was effective improving their immune functioning so external validation would be sufficient for this study.
Statistical information shows that the difference between the treatment group and the control group wasn't significant but still shows the improvement on immune system and effectiveness in Jeremy's test.
The drug improved the participants immune functioning as it claimed it would so costruct validation would be sufficient.
We cannot be sure that the drug stablishes a trustworthy cause and effect relation between treatment and outcome on patients and alternative explanations can be found since there was an improvement on the control group immune system as well.
Internal validation requires a trustworthy cause and effect relationship between treatment and outcome stablished by the experiment so it isn't sufficient for this study.
Chronic villus sampling (CVS) is the name of the test.
