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.
2. Biological differences between human beings reflect both hereditary factors and the influence of natural and social environments. In most cases, these differences are due to the interaction of both. The degree to which environment or heredity affects any trait varies greatly. 3.
Furthermore, their small sample size also limited the research. Small samples limit generalizability and our ability to account for moderator variables such as history of recurrence or comorbid conditions. The results would likely be strengthened with a larger sample. Lastly, 70% of participants were low-income, inner-city African-American females. While the findings suggests that ABFT is an effective intervention for this particular population future research should look at a broader
Professor Petersen-Mahrt Svend of SEMM The European School of Molecular Medicine states that E. gracilis has a high sensitivity to environmental changes such as the change in pH levels (Petersen-Mahrt 1997). The pH level [of the environment] can directly distress the absorption of nutrients in marine environments. E. gracilis has been found to endure an expansive range [compared to] other algae (Danilov and Ekelund 2001). Through studies done by William J. Robbins, a botanist from Columbia University, E. gracilis has been found to grow best at a pH level of 3.0
What changes do you expect in abiotic conditions in or just above the sediments to those in the water column at the same site? • There would be a difference in the water temperature. Given that the water column is closer to the surface than the sediments, it is more likely to have sunlight reach this area, increasing not only temperature, but also the type of organisms that need sunlight to live. Another aspect that would be different would be the nutrients that is present in the two different habitats. How might a species of organisms and their abundance differ between the habitats, and might any differences be related to differences in abiotic conditions?
Some people from SJR are careless too but I still think that there is a higher number of careless people in public schools than in SJR. Wealth does encourage carelessness but in SJR wealth doesn't seem to have an affect on how a person is. That's why I wouldn't really like to attend a school where there is less conspicuous
In order for integration to achieve, there must be an acceptance between two or more cultural groups (usually in multicultural areas). To fully explain integration, individuals must consider that integration not always creates a positive and engaging impact, but can create negative environments. Integration is the most competent and adaptive strategy because it positively provides benefits to cultures with mutual accommodation. Compared with the other acculturation strategies, integration is associated with lower levels of risk behavior and more positive attitudes, and better psychological and sociocultural outcomes in youth. In Berry’s (2011) study, most students chose integration as their efficacious strategy of acculturation, because statistics show that the majority of the students do not deliberately separate or integrate from the German society (Yu & Wang, 2011).
Asians enjoy privileges few other minorities have, such as a higher percentage of college graduates. However, due to the success of Asians, stereotypes have formed around the perception of “the model minority”, mainly that Asians are found to be competent, cold, and non-dominant (Berdahl & Min, 2012). With any stereotype, there is room for misunderstandings and discrimination, and this is no exception. One of the most common forms of discrimination is in career acquisition. If an employer has a negative view of potential candidates, this creates a skew in the rate at which races might be hired for certain jobs.
Many have jobs and other responsibilities, but are not politically involved. According to a professional, “16 is a better age for gaining the knowledge needed”(Williams). Therefore, lowering the voting age to 16 can get teens politically prepared. Finally, by lowering the voting age, it will give politicians a reason to respect the desires of teens. If teens are able to vote as well, politicians will get more votes, which will lead to them having more respect towards teens.
Height also creates variety among individuals, whether a person is tall, short, or average. There are many aesthetic differences among our species, but 99.99% of DNA found in humans is the same around the world (Stanford University). Differences in a population do make some individuals better at some things while not well suited for others. For
Some subtle details that I observed in the field are that the north was more developed by humans while the south was more natural. I also saw a much denser canopy in the south and the trails there were rockier than the north. The denser canopy could suggest that the south would contain more shade tolerant species. This is supported by the larger number of Thuja plicata and Acer macrophyllum in the south. However, this can be refuted as well, since the north had a larger amount of Polystichum munitum and Tsuga heterophylla, both of which are also shade tolerant.
Mutation did occur in some of the rounds we did in the experiment by having more birds with longer beaks and smaller ones decreasing dramatically. But eventually birds with smaller beaks will adapt to another environment and as for long beak birds they will have to challenge one another to fight for food and probably over time have a hard time searching for food. But it wasn’t natural selection that changed the beak size of the birds it was basically a mutation that was passed on to their
From figure 3 and 4, it seems to show that the level of starch rises in proportion to the concentration of salivary amylase. However, it seems that there are some data points that extend much greater above the average. This means that those points can be called into question as it seems unlikely that a person could create almost 17 ml of salivary amylase (figure 4 error bars). It is obvious that out range error and standard deviations extend greatly in the negative X direction as well as the positive X direction. When taking into account of the sources of error this data, and smaller sample size, many things contribute to increasing the large data spread of error.
How does tanning work? The pigment of your skin is determined by the amount of melanin produced by your skin cells. How much melanin your cells produce depends on your race and genetic make-up, but also depends on how much sunlight your skin is exposed to. When ultraviolet light touches your skin your cells start producing more melanin, making your skin look darker. That extra melanin protects your cells by absorbing radiation from the sun.
