Skin immunity is a property of skin that allows it to resist infections from pathogens. In addition to providing a passive physical barrier against infection, the skin also contains elements of the innate and adaptive immune systems which allows it to actively fight infections. I hope that this helps.
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.
