The wand was dipped into the Flynap and then placed into the tube for a few minutes until the flies were asleep. Once the flies were asleep, the wand was removed and the flies were distributed. From this point, the flies were counted and their sex was determined under the microscope. The monohybrid cross was sex-linked, wild x wild eye colored flies. The dihybrid consisted of vestigial winged flies x sepia eye colored. An even amount of males and females were placed in the vial tubes using a teasing needle, one labeled monohybrid and the other dihybrid. Within each tube, there was some culture media for the flies to survive and reproduce for about a week. After giving the fruit flies time to reproduce, they were put to sleep again using the Flynap and then the progeny were taken out to be counted and observed. The results were recorded and the same was done for the following generation,…

Claude Bernard, a French physiologist, once said "Science teaches us to doubt". An account of the 1918 flu epidemic. "The Great Influenza" by John M. Barry provides characteristics to become a successful scientist. Additionally, Barry accounts for the contributions scientists have made to the field of science. Barry plays an important role in shaping the perspective of a scientist and the importance of a scientist.…

In science, biologists use some species as a “bioindicator” in a marine ecosystem, that reflect on the quality of the environment. This method is very accurate and a bioindicator species can detect problems that physical and chemical testing cannot detect. Similarly, in William Golding’s adventure novel Lord of the Flies, a group of young boys are stranded on an island and build a miniature society there, and there are many symbols within this society that reflect on the quality of the environment there. The unfit but intelligent boy named Piggy owns a pair of glasses can be used by the reader throughout the novel as a bioindicator for the quality of the environment there on the island. Piggy’s glasses represent rational thinking and reflect on the strength of the boys’ reasoning; as the logical reasoning of the boys begins to atrophy, the glasses also become damaged.…
“An experiment on a bird in the air pump” was oil painted by Joseph Wright; He was best known for his paintings of industrial scenes, and for his dramatic use of lighting famously known as furnace light and candlelight. This artwork (completed in 1768) is also one of his artwork expressing one of the days in the industrial revolution. However here in this artwork, he has depicted a scene of a traveling scientist demonstrating an experiment which proves suffocation. As the art work expresses, a scientist which faces towards us is showing the audience how the bird will react when the air surrounding is pumped out. The equipment used is clearly an air pump as we see, and its air in the glass bulb containing a bird as well, has been sucked out by the vacuum. The air pump was invented in 1650 which is roughly a century before this artwork was completed, and was first used on animals a decade later by English scientists who investigated the effects of “impeded respiration” on larks, sparrows, mice, kittens and a number of other small creatures. The artwork shows the image of how the pumps were used, and records the history of how science was like back then. Wright has used the drama of the demonstration to show the impact of the experiment on ordinary people. As we see in this painting, each shows differing emotions and facial expression which exemplifies the reaction of the experiment. We can see a young man holding a watch, which as we assume, he is timing the experiment. Perhaps he is timing the bird’s convulsions and ultimate death, or maybe he is responsible for indicating to the lecturer the exact moment to readmit air into the receiver. On his left, a young boy is sat while watching with genuine curiosity. A young couple behind stares at one another, and we could sense that they are completely in love and contains no interest in the experiment. Looking at the couple, we could tell that back in the days, young love wasn’t quite accepted yet and that only when…
Jargon is used also as a way to present his readers with photography knowledge. He uses a quote from the photographer which says “…to give a refreshing view on insect marco-photography”. By using this the author gives the public a small insight to what technology goes into taking these photos. This uses of jargon also presents another purpose as it shows the photographer of these fly photos to be a professional within this business. Also that it makes it easier for people who know about the subject to follow, as specialized terms can be used without losing information. This is useful as he has a very wide audience and some may understand these terms.…
What does it take to launch an ultra-light fishing line over 200 feet? A little physics and a lot of feel for the fishing rod, that’s what. The trick to doing good is to have the thinner, end of the line, land on the water first then the fly. The end of the line cushions the fly, having the effect that a fly is landing on the water, not a piece of nylon string. This may sound easy, but it’s a lot harder than it seems. Just getting it to go that far is like “pitching a cotton ball at major league speeds.”…
The sample size of this experiment was quite small; this may have affected the accuracy of the experiment, preventing the hypothesis from being tested properly. This could be overcome in future experiments by breeding more flies and…
We were excited, until I made a mistake and got all of the F2 generation flies stuck in the median, and the mass majority of the flies died. Luckily though, our instructor, Mrs. Mahan, allowed us to find a group that we felt were near what we may have had. We chose a group, and we had to borrow their data for the rest of the lab. The failure of my group’s lab was entirely my fault, due to the fact that I had not been listening at the time, andI take full responsibility as such. If it weren’t for that, we would not need to be using someone else’s data to finish this project. The other group’s flies did about as good as ours, and we asked if we could borrow their data. They ended up having one hundred and thirty three red eyed, winged flies, twenty two red eyed wingless flies, thirty four brown eyed, winged flies, and five brown eyed, wingless flies. This meant we ended up totaling our number of flies at one hundred and ninety four flies. Hear is a table to show our…
I can still picture my grandpa gently yet deftly catching me a blue dragonfly by hand. Although normally rambunctious, I sat still in order to observe the foreign critter. Peering into the captive dragonfly’s multifaceted, slightly metallic eyes filled me with a sense of wonder. I sat mesmerized for what felt like hours until my grandpa released it and it zoomed away.…
Scientists have long suspected that there is a dramatic decline in insects and it seems that their fear has turned into reality. Research at more than 60 protected areas in Germany says flying insects have declined by more than 76% over the last 30 years. The causes are currently unknown, but this is very concerning for the environment because some insects kill of…
Drosophila melanogaster is a fruit fly, about 3mm in length, and it is the insect that flies around spoiled fruit. 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 or more space for survival, and the life cycle for a fruit fly is about 2 weeks, and they share about 60% of DNA with Homo sapiens (NASA).…
2. In order to utilize fruit flies in experiments several techniques with multiple steps are have been developed. The techniques and steps used for this experiment involved: anesthetizing flies, where carbon dioxide is used for keeping the flies static for relatively long periods of time with no side effects. Transferring flies from one vial to another is done by placing a funnel in the top of a new vial containing madia, then gently tapping the old vial so the flies fall to the bottom of the vial. Once the flies are the bottom of the vial remove the plug off and invert the vial into the prepared vial with funnel.…
The beauty of flying is often downplayed and viewed merely as a method of transportation. However, it is much more than that because it not only helps the local and global economy, but allows people to have an amazing experience. Flying is so much more than that in positive and negative ways. The poem, “Flying Lesson” is misleading in a way. Upon initial observation of the poem, some think it is talking about flight training. This “flight training” is aimed towards the reader because it’s trying to explain what flying truly is about. Flying is an art, flying involves all five senses. Flying is a hobby, Dolores Hayden’s, “Flying Lesson” illustrates the the dangers and joys of flying to the reader. The speaker in the…
