enyata [817]

The question posted above is incomplete, here is the complete version:

To find out which ingredient the cockroaches are refusing, you carry out a controlled experiment. Hydramethylnon is dissolved in oleic acid before being mixed with corn syrup to prepare the poisoned bait, so you should test all three ingredients. Suppose you conducted a feeding trial to test each ingredient. In the trial, a set of four agar dishes, three containing all except one ingredient and one with all three ingredients (the control), were weighed and placed 3 cm apart on the kitchen floor in an infested apartment. After two days, the dishes were weighed again to measure food consumption. You then repeated the trial 4 times and averaged the results. Here are the results from your experiment.

Tested (absent) diet component   Average food consumed (mg/day)

Hydramethylnon   16

Oleic acid   12

Corn syrup   71

Control (all three ingredients present)   15

Based on the results of the feeding experiment, what conclusions can you draw? Select all that apply. (For help interpreting the results see the hints.)

1. Roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish.

2. Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.

3. Roaches ate about the same amount from the dish with no corn syrup as they did from the control dish.

4. Roaches are refusing hydramethylnon.

5. Roaches are refusing oleic acid.

6. Roaches are refusing corn syrup.

ANSWER:

The conclusions that apply include the following: 

1. The roaches ate about the same amount from the dish without hydramethlynon as they did from the control dish. 

6. Roaches are refusing corn syrup.

As we can see from the results obtained above, the amount of food consumed by the roaches when hydramethylnon is absent (16 mg/day)in the feed and that consumed from the control dish (15 mg/day)is almost the same quantity. From the results also, it can be seen that the highest quantity of food (71 mg/day) was consumed when corn syrup was absent in the feed, which implies that the roaches are refusing corn syrup.
