Question

Chapter 4 Homework Exercises I. Consider each scenario below (reprinted from Hw #1 in Chapter 2). For each scenario indicate the dependent variable, independent variable, and a possible hypothesis a. A washer was tied to one end of a string. Two students measured the time it took the washer to swing back and forth for different string lengths. For a 1 m length it took 2.0 seconds. For a 1.2 m length it took 2.2 seconds. For a 1.4 m length it took 2.4 seconds. b. Graph shows population size over a period of 30 generations. 00+ 1 101 20 2 c. The graph represents the amount of product created in a reaction aided by one of two enzymes Enzyme A is represented by the line mostly on top and Enzyme B is represented by the line with the sharper peak.] 12 E 10 a. o 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 Temperature (Celsius)

Explanation / Answer

1) independent variable here is length of the string and the dependent variable is the time to complete one swing.

time is depending on the length.

and the hypothesis is t = 1+ l

2)independent variable is generation

dependent is population

3)independent variable is temperature

dependent variables are the amount of two products
