Question

In an experiment, 90 newborn flies are divided evenly into three separate groups and placed in boxes inside an incubator that is maintained at a constant temperature of 30°C. On a daily basis, the first group is given water containing 1 mg/mL of sugar; the second is given water containing 2 mg/mL of sugar; and the third is given water containing 3 mg/mL of sugar. After four weeks, the average length of the flies in each group is determined. What should be the title of the line graph that displays data from this experiment? A. Average length of fly (mm) vs. concentration of sugar (mg/mL) B. Concentration of sugar (mg/mL) vs. average length of fly (mm) C. The effect of changing the concentration of sugar (mg/mL) D. The proportion of flies in each of three experimental groups

Answer 1

Answer:A. Average length of fly (mm) vs. concentration of sugar (mg/mL)

Explanation: the data collected in the experiment is the length of the flies and the concentration of sugar, so that's the information that should be on the title.

Additionally, in every experiment there are dependent and independent variables. Dependent variables are those that depend on the values or variation of independent variables and these independent variable are those that you can control in the experiment, so you decide the values.

The dependent variable in this case is the length of the flies that relies on how much sugar they eat, so the independent variable is the concentration of sugar.

Finally, data graphs are always title like this: dependent variable vs independent variable because dependent variable goes in the y axis and independent goes in the x axis

Answer 2

The correct option is A

A. Average length of fly (mm) vs. concentration of sugar (mg/mL)

Step-by-step explanation:

An experiment is conducted, in which 90 newborn flies are divided evenly into three separate groups and placed in boxes inside an incubator that is maintained at a constant temperature of 30°C. On a daily basis, the first group is given water containing 1 mg/mL of sugar; the second is given water containing 2 mg/mL of sugar; and the third is given water containing 3 mg/mL of sugar. After four weeks, the average length of the flies in each group is determined. so the tittle of the study will be "Average length of fly vs.concentration.
