A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food

Neonicotinoids‚ nicotine-similar pesticides‚ threaten bee populations‚ which pollinate agricultural crops‚ ensure food security and maintain biodiversity. Scientists Sebastien Kessler and Maj Rundolf sought to understand pesticide effects on bees. Through a laboratory study‚ Sebastien Kessler tested abilities of honeybees and bumblebees to taste common neonicotinoids. Unlike Kessler‚ Maj Rundolf assessed neonicotinoid impacts on bee colonies’ near canola fields. Each scientist had a unique plan
