1. What is the scientific name of fruit flies?
The scientific name of fruit flies is Drosophila melanogaster.
2. Why are fruit flies used in scientific research?
Fruit flies are used in scientific research because we, as humans, share 75% of the genes that cause diseases in us with them. This allows scientists to studying genes that exist in humans without actually experimenting on humans. In addition, it is not hard to take care of fruit flies and scientists can study them without spending a lot of time taking care of them. Their size also makes using them in scientific research advantageous. First of all, they are small enough so that scientists can store many of them at once. However, these flies are also large enough for us to be …show more content…
These eggs are each 1.2mm long. Mother fruit flies try to lay their eggs in foods, such as fruits, or manure, which the new born fruit flies can eat when they are born. When the flies hatch and enter their next stage, the flies are known as larvae. The larvae look like 3mm to 9mm long, white, tiny, wriggling, pills. The larvae stage lasts about seven to eight days. The larvae undergo three instars. During these instars, the larvae shed their cuticles, mouths, heads, hooks, and spiracles. During the third instars of the larvae, they climb into a dark area to pupate. As the larval skin darkens and hardens, a pupa case is made. This is called the pupal stage. The pupal case is about 8mm in length. During this stage, the flies undergo metamorphosis. Flies can stay in the pupa stage for three to six days. After metamorphosis, the flies than climb out of the operculum, the front part of the puparium. At this point, the fly has entered its final stage: The Adult Stage. To summarize, the fly life cycle contains four major stages in total. The stages, in order, are the egg stage, the larva stage, the pupal stage, and the adult …show more content…
What are the physical differences used to distinguish male from female flies? YOU MUST EITHER ATTACH AN IMAGE OR HAND-DRAW AN IMAGE in addition to a description
First of all, the abdomens of female flies are pointed and on their dorsal surface, which is on the back of the fly, there is a pin-like structure. On the other hand, the abdomens of male fruit flies are more circular. Females also have thin dark colored bands on their abdomens while the abdomens of the males are completely dark. The genitalia of female fruit flies are barely visible while the male fruit flies have easily seen structures on their undersides. Lastly, while males possess a row of dark fibers called sex combs, females possess no sex combs at all.
