Chpt 1.6: Doing Biology

Question 1

Hypothesis

Answer 1

a tentative explanation of an observed phenomenon that answers the question why?

Question 2

3 Traits of a good clownfish prediction

Answer 2

1. Accurately reflects/describes the independent and dependent variables to be studied
2. Describes how measurements will be made
3. Does NOT need a ‘because’ statement
   exp. Green anemones will have a greater frequency of clownfish visitors per hour than white anemones.

Question 3

Prediction

Answer 3

a statement of what you expect to observe if your alternative hypothesis is correct in the specific experimental circumstances in which you will test your hypothesis

Question 4

4 traits of a good clownfish hypothesis

Answer 4

1. Includes info about the initial observation without giving away the independent or dependent variable too explicitly
2. Isn’t so specific that it can only be tested in one way
3. Has an appropriate ‘because’ mechanism
4. Doesn’t use circular logic
   exp. Clownfish typically utilize less venomous anemone host species rather than more venomous hosts because their mucus coating provides insufficient protection from the more potent venom.
