Through concise analysis of research papers and other experiments conducted elsewhere, the final conclusion of this lab was supported. All in all, the inquiry experiment allowed the accomplishment of the goal of identifying one of the main reasons why fruit flies eat rotten fruit. Introduction: Drosophila (a model research organism) melanogaster (black abdomen) is the common fruitfly. The lab required the usage of fruit flies as they are a commonly used organism in many experiments. The portion before the inquiry lab utilized the usage of different foods to determine exactly which food the flies would experience more of an attraction towards.
Rusty-patched bumble bees specifically play a role in the pollination of various plants, foods, and other agricultural resources. Once upon a time, the bumblebees spanned a wide range across the northwest, northern, and northeast states, however, due to an increase in human impact, the bees are experiencing an alarming decline as sharp as 87 percent in the last 20 years, as noted by the USFWS. Some of the reasons for decline can include habitat loss, intensive farming, disease, insecticide use, and climate change. Over time, as these harmful conditions for the bees become more prevalent, there is a correlating decrease
Neonicotinoids are said to be the most popular pesticides in the United States. We can save the honeybees in one way. The farmers can help honeybees survive by changing their farming habits. The bees only work in the daytime so if we limit the use of pesticides to evenings that will help out. The farmers also have liquid pesticides they are less toxic than other
South Korea has the most cosmetically enhanced people as plastic surgery is considered as a key to better careers and to a happier life. The ideal face that is considered ‘beautiful’ contains these features: big round eyes, a pointed nose, a pleasant smile, a v-shaped chin, and a slim jaw. Yang Yoon stated, “While plastic surgery may seem like a tool for looking better, it’s actually all about comparing one’s self to others.” Plastic surgery is such an interesting topic to me because of how sophisticated and complex the reasons and facts are behind it. This would be a good source since it discusses cosmetic procedures in the country that performs it the most.
Overall, the lab provided expected results. Most of our hypotheses were correct, including Dim vs. Red, Dim vs. Blue, and Dim vs. Black. We hypothesized that Drosophila Melanogaster would prefer dim light over all colors, especially blue and black due to the fact that they have very short wavelengths which are lethal to the flies. However, results from 2 out of our 5 trials did not support the hypotheses. In the initial trial, Dim vs. Dim, we expected an equal number of flies on each side of the chamber due to the same lighting on both sides.
To find a cause you must look to the biopsychosocial model, or the combination of biological, psychological, and social factors that take part in the development process in a functioning brain. The biological factor is examined in multiple studies, an example of a study that was done is by a group in the Netherlands that looked at monozygotic and dizygotic twins and their families, The studies showed “that genetic effects explain 35 to 45% of the variance in borderline personality disorder and borderline personality features” (Distel M., 2009) this and other classical twin studies are important because it detects the genetic influences of BPD features. While the genetics play a big part in the etiology of BPD so does the social factors. It is common that individuals who suffer abuse or neglect in childhood can develop BPD; in addition to this individuals who had learning disabilities or suffered from alcohol and drug abuse can develop BDP. This is due to the negative social attention the individual receives from interpersonal relationships.
“The other SS who helped unload the transports had been given special instructions to find twins, dwarfs, giants, or anyone else with a unique hereditary trait like a club foot or Heterochromia (each eye a different color)” (Rosenberg 1). Heterochromia was another big study for Mengele because of how Mengele wanted to find a way to birth Aryan children with blond hair and blue eyes. So when a twin specimen died, he would take the eyes and sent them to his colleague, Karin Magnussen, a KWI researcher of eye pigmentation. Another way to try to fabricate blue eyes, Mengele would inject or drop different types of chemicals into specimens eyes in order to achieve a result that satisfied
Intelligence quotient is a score from a standardized test which assess human intelligence. The first I.Q. was created by Alfred Binet, who was a French psychologist, that created this test to determine the population of students and the difficulty they would have at school. This test was modified in 1916 by Lewis Terman who used it in the American population, specifically, American soldiers. The I.Q. comes from the equation dividing the mental age by the chronological age and multiply by a hundred. The average I.Q. of a person with Down Syndrome rages from seventy to eighty compared to the I.Q. of the general population which is seventy to hundred and thirty (Global Down Syndrome Society).
Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. It makes daughter cells with exactly half as many chromosomes. Meiosis in humans is a division process that makes a diploid cell (one with two sets of chromosomes) to haploid cells (ones with a single set of chromosomes). PHASES OF MEIOSIS
Statistical Analysis Data were tabulated, and analyzed using the computer program SPSS (Statistical package for social science) version 17 to obtain descriptive statistics that was calculated in the form of frequency percentage The statistical comparison between different groups was carried out using one of the following tests:- 1- Inter-group comparison of categorical data were performed by using chi square test (X2-value) 2- Freidman test: for comparison of more than two related groups with non-parametric data A P value <0.05 was considered statistically significant.

After comparing wild type and mutant flies, no differences were apparent during the larva and pupa stages. Newly- enclosed adults appeared the same in all aspects except for the coloration of the eyes, as well as adults that were several days old.
Why are fruit flies even significant to biologists? They are actually one of the most valuable organisms to biological researches because they can be used as models for research in genetics and development. Fruit flies are easily stored, cheap, and are very well understood. They are very easy to handle and

A few examples of these mutations involve eye color, wing formation, body size and body color. When comparing the wild type version of D. melanogaster to mutant D. melanogaster with unknown code 651, it was shown that the mutant contained a mutation in the bristles located on the fly’s thorax and head.
The effects of where these larvae are laid can dictate the fate of these gall fly larvae. A study shows that avian predators can assess a gall 's content prior to pecking it open, preferring galls that are inhabited by gall fly larvae. Bird predation was found to be concentrated near the places with a lot of tree cover where S. gigantean a large centipede tends to pray few attacks occurred in the open where golden rods are prevalent. The study was a field experiment to observe the preference of avian predators on galls in different habitat types and that had different sizes, and heights of galls. It is possible that birds have either learned through experience or evolved through natural selection to choose the more profitable galls (Poff et al. 2002).
