Questions
1. Models are analogies that allow us to clarify hypotheses-proposed explanations of relationships
between causes and effects. What roles do models play in testing hypotheses?
2. What did the humoral model of disease propose as the cause for cholera?
3. What did the miasma model of disease propose as the cause for cholera?
4. Unlike Snow's later work on cholera, his research on anesthesia was experimental in nature. What
general skills of experimental design were necessary to plan effective experiments to test dosage
measuring and delivery systems for anesthesia, or to investigate the properties and effects of different
drugs?
5. Why are experiments considered strong tests of hypotheses?

models provides testing of hypothesis.

Humoral model proves that the cause for cholera is contaminated food and water.

Miasma model of disease suggested that bad air is the cause for cholera disease.

experiment provides testing of hypothesis.

Explanation:

Models helps to test the hypothesis and provides the procedure for the physical testing of it. Humoral model of disease proposed that contaminated of food and water is the main cause for cholera. Miasma model of disease proposed that bad air is the cause for cholera disease. Experiments are considered strong tests of hypotheses because experiment is performed physically while hypothesis is the assumption made by the scientists.

i dont know it at allnow im just getting points at this pint
