You set out to observe the symbiotic relationship between a species of orchid and a species of fly. This species of orchid is only pollinated by this one species of fly, and the flies seem to prefer that orchid over any other flower for its nectar supply. Identify and describe two reasons for the proximate causation for the species-specific preference of this fly. Select one of the reasons and make a prediction on the outcome on species-specific preference of the fly. Justify your prediction with evidence.

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
