Biology Lab Hypothesis

In the control it averaged to be better than the experimental group. On November 2nd control 1, 2 and 3 showed a lot of growth ranging from 9.5- 12cm and sadly control 4 dead, throughout this project we could have changed something different to make all the plants grow the same way. However, on the last week Plant # 2 and #3 grew very large and made much more progress. Discussion/Conclusion

1. The authors from this experiment were trying to gain information on how the diversity of gut microbes in humans evolved the CAZymes, to supply the body with its energy needs, from microbial populations living outside the body. 2. It is known that sulphated polysaccharides are the origin of carbon for heterotrophic bacteria that make the CAZymes in marine organisms. Also, these enzymes have been seen throughout human evolution to locate polysaccharides in terrestrial plants that have been eaten.

Hypothesis correct?: Yes and no. The tap water did soak up the color best, however the plants in soft water and the reverse osmosis

The 50,000 rads tray had shorter, straight, green stems and 2 leaves per seed. Next, the 150,000 rads tray: has 2 leaves, and green, straight stems. The tray with 500,000 rads had slowed growth asd were not as green. The tray with 4 million rads had the worst appearance, nothing grew, due to too much radiation applied to the seeds. The overall appearance and health was the best in the control because no radiation was applied and the 4 million rads was too much, so the seeds did not

The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

Introduction: Evolution is the change over time for an organism or thing. As in how organism were quadrupedal to bipedal and how organisms bodies adapted to a form to better support its body in its environment. Evolution is based and showed as the changes to an organism over time, and it explains the common ancestry to two common species. The biggest evidence scientist use regarding evolution is fossils.

The sixth lab I completed in Biology 101 taught me how autotrophs (self-feeders) and heterotrophs (other-feeders) make organic food molecules by using photosynthesis. Photosynthesis uses the energy from the sun and it is captured and stored in the chemical bonds of organic molecules. The sunlight consists of different wavelengths of light. In plant chloroplasts, they have different pigments that capture different wavelengths of light. Light capturing pigments in green plants are called chlorophylls and these absorb all the colors of light except green, which is mostly reflected. To separate molecules from each other according to their solubility in a particular solvent is done by the process of chromatography. This basically means that polar

Were there any sources of error that could have contributed to false data in our experiment? The fast decline of the room temperature, was a red flag. Why would a sample that appeared to be healthy and thriving suddenly die within the span of 7 days? The possible sources of error I can predict regarding that part of the experiment would be the fluctuations in light based on its location in the room and amount of water that was filled on day 12 as possibly someone in the group forgot to refill the sample after noticing evaporation. The fluctuating temperature changes inside the room as well as the weather conditions and temperature conditions outside is also a possible source of error regarding the sample. I cannot identify any sources of error in regards to the fridge and incubator samples as their results could be backed up by our pre-lab research on duckweed growth in hot and cold

realize that the plant was having an accident with the coolant level. The tubes holding the nuclear fuel began to melt since they became over heated which also caused fuel pellets to melt. Even though this was the most dangerous kind of nuclear accident, the radiation did not reach outside of the containment building nor did it release out into the environment. There were no immediate injuries or deaths reported from the raditation to the faculty workers.

Also, there were studies done on the effects of the radiation released in to the environment due the accident.There were many samples of air, water, and vegetation taken by people who were monitoring the area, and none concluded that the accident caused damaging effects on the environment.[10]

Despite having extremely conservative foreign direct investment guidelines, the government of China has been successful in attracting foreign investment. Proper implementations of Human Resource policies for international strategic alliances have always remained as a real challenge in the country. In order to adjust in the Chinese market, international banks have customized their policies and lending criteria and the government has also restructured their banking policies and information technology services. Before setting up an international business, various factors should be considered like finding the perfect strategic fit which should also be in line with the Chinese culture and value culture.

The death penalty is a form of execution used in the United States. The federal death penalty can be used in any state or territory of the U.S. even in states that do not have it. There are currently 32 states including North Carolina that have the death penalty. Its purpose was to deter crime from happening. Therefore, creating a safer environment. Unfortunately this has not been the case. The death penalty has claimed innocent lives, ruined lives, is issued at random & unfairly, and does not decrease the crime rate. It should be abolished by all states because it does not work.

The law proves that natural selection is necessary for evolution to occur ("SparkNotes: population genetics," 2014). The conditions set up by the Hardy-Weinberg Law allow for variability (the existence of different alleles) and inheritance, but they eliminate natural selection ("SparkNotes: population genetics," 2014). The fact that no evolution occurs in a population meeting these conditions proves that evolution can only occur through natural selection ("SparkNotes: population genetics," 2014). The Hardy-Weinberg Law allows us to estimate the effect of selection pressures

life is our most valuable gift, but as we choose to do things or situations that may harm us we forget the idea of valuing our lives. The movie seven pounds showed us that Ben Thomas was willing to help people's lives after he kill his wife and others in a car accident. He no longer valued his life but believed there was people out there valuing their life more than himself. Having an illness or suffering in any way will help us realize we need to value our gift of life more often. As we lose the value of our lives we may no longer find happiness in our lives.
