Explanation:
-All theories have enough supporting evidence behind them that we can move forward under the assumption that they are correct unless some future test proves that this is not the case.
-A theory has a higher probability of accurately modeling a natural phenomenon than a hypothesis does.
Further Explaination:
Scientific investigations usually begin with observations. These are typically something that would catch the researcher’s attention. Then, the scientist comes up with a hypothesis which is a testable explanation for the phenomenon or what’s occurring a prediction is usually made based on the hypothesis.
A prediction of the outcome is usually made based on the hypothesis...after which it is tested via an experiment. The scientist then use the results to make new hypotheses or predict certain outcomes.

That really depends on your doctor. Some people are high at 140 and others at 130 for the systolic. If you are young, I think 130 is pretty high. If you are older maybe 140 if the point where you should be paying attention.
For the diastolic 80 is good. 85 is take a note book when you go see a doctor and 90 it's time to be a worry wart.
These are just numbers. Throughout the day, the numbers can vary quite a bit so one bad reading does not make you a candidate for high blood pressure.
If you learn to relax before it is taken, it makes a 10 - 15 point difference on the systolic and don't let people bully you about it.
Answer:
It suggests getting a physician's input before starting.
Answer:
The correct answer is 2. Usually multiple mutations are required in different genes to cause cancer.
Explanation:
Mutation is the change in the DNA sequence of a cell which plays an important role in causing cancer. Mutation in many different genes allows the cell to grow and multiply in an uncontrollable manner. It also allows the cell to gain the property of metastasis.
Metastasis is the property of malignant tumor cell which allow the mutated cells to invade different tissues and organs and multiply in numbers. This property plays an important role in causing cancer. Therefore several mutations in different genes are required to cause cancer. So the correct answer is 2.
