Question

2. Caffeine has stim addictive. Some plants produce published in Science on how caffeine in floral nectar of plants can influence pollinator behavior ulatory properties in vertebrates (like you), but also in invertebrates, and it can be floral nectar with caffeine in it. The figure below comes from a study a full interpretation of this data in the space below. Figure 1. Bees were exposed to a particular floral odor while they were simultaneously fed a nectar "reward" consisting of a 0.7 M sucrose solution either without caffeine (control) or with one of seven different concentrations of caffeine. Bees were tested later for their ability to recognize the floral odor at 10 minutes and 24 hours after exposure to the odor. The y-axis is a measure of the proportion of bees correctly remembering the odor at each time point and with each nectar reward. Concentrations o 10-10 represent concentrations of caffeine that can actually be found in floral nectar of plants that produce caffeine. 0.8 10 min 24 h 0.6 0.4 0.2 0.0 Control 10-9 10-8 10-7 10-6 10-5 104 10-3 Concentration of caffeine in reward (M)

Answer 1

Data interpretation: - The data provided in the problem shows a memory recall test for order at 10 min(clear bars) or 24 hr(shaded bars)after bees hart been trained. shaded bars indicate that the response at 24 hr was significantly different from the control(0.7 M sucrose) When bar were rewarded with solutions containing nectar - levels of caffeine, there times as many bars remembered the conditioned scent 24 hr later & to responded as if it predicated reward.
