Explanation:
Because in the above experiment which is designed to test that, in the above cage these three flies prefer which type of food either it is a banana which is fresh or either apple which is rotten.

Answer:  
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit  
Explanation:  
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
