Since the p value was greater than the alpha level, it indicated that the results were not statistically significant (Bridge etal 2015). We did not reject the null hypothesis and reject our hypothesis. Based on the tables and graphs that were constructed, we were able to see that the sodium chloride acted as a hypertonic solution for the yam cores compared to the water (McGraw-Hill Education 2003). Although we were able to visually see a difference between the two solutions, it was not significant enough to reject the null hypothesis. Since a yam is a plant of the genus Dioscorea, it contains cells that are partially permeable membranes.
If they cannot obtain water, they would not be able to perform photosynthesis and prevent it from contributing to the NPP. The nutrient density of soil matters because it would keep the plant in place so it can grow. It also provides nutrients the plant needs to become healthy and strong. If the plants in the habitat had low nutrient density of the soil, they would be struggling to survive, thus producing less energy and a less NPP in the
Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers). Harrison describes Eutrophic lakes as highly productive and turbid due to algae being present. Furthermore Harrison states that oligotrophic lakes have low productivity and are clear in the
Many neighbors of Almaden Lake are against it because they feel that their are many more solutions that could work and are cheaper. They feel this way due to the money used for the system will be out of the district parks funds and they think the money should be used for other things like better campgrounds, supplies, and etc.. but at the same time they feel it would benefit tremendously because they can finally eat the fish out of the lake, bring more fishermen to the lake, and will be a better attraction for people. At this time, the park is currenting maintaining the mercury levels with solar powered circulation systems but they are temporary . So far though, the circulators have not improved the reservoirs’ water quality. They are many other solutions but none are permanent, the park will continue using this system until they can follow through with the oxygenation system.
- Little to no oxygen will result in the E. coli cells producing large quantities of acetic acid, causing the growth medium to reach pH 4 or lower however, with proper aeration the cells will be able to use many organic acids as carbon sources and the pH of the growth medium will be maintained at neutral or basic ranges. Aeration is another important factor in determining E. coli cell growth however it can continue to grow in the absence of oxygen using fermentation and anaerobic respiration. - Optimal growth temperature is 37C, cannot grow well at temperatures higher than 42C and they can tolerate lower temperatures with lower growth rate. - The doubling time or generation time for most E. coli strain in a rich medium at 37C is 20 minutes. - E. coli requires environmental sources of all of the nutrients (carbon, hydrogen, nitrogen, oxygen, phosphorus, sulphur, as well as iron, selenium, calcium, sodium and several others) in order to survive.
How might a species of organisms and their abundance differ between the habitats, and might any differences be related to differences in abiotic conditions? • The species would differ as a result of abiotic conditions. This is because certain organism need sunlight to survive, and other nutrients that are only present in the water column of the lake. However, there are organism that live in the benthos that could not survive in the water column due to many different reasons, one being the inability to float in the water.
The Use of PCR and Gel Electrophoresis to Examine the Pitx1 Enhancer Region in the Stickleback Fish of Big Lake Hypothesis: Due to selective pressures in a freshwater environment, the stickleback fish in Big Lake will not have pelvic spines due to an insertion mutation in the Pitx1 enhancer region. Rationale: Since these stickleback fish are found in Big Lake, which is a freshwater lake that does not experience a marine environment, they will not have pelvic spines due to the specific selective pressures they experience. In Big Lake, the calcium levels is 14ueqv/L, which is much lower than the calcium levels found in a marine environment. This can result in less bone growth, and a lack of pelvic spine found in the stickleback fish. There
Introduction: Biodiversity is important for all living organism including plants and animals. Without biodiversity, there would be no balance between organism and their environment. Biodiversity helps to maintain the balance of nature to sustain all life on earth; one species will not overpower another because of the effect of biodiversity. Not only does biodiversity maintain the balance of nature it is also used to indicate health in the aquatic community. Dissolved-oxygen is measured in the aquatic environment to test the health of the water.
What is the impact of utilizing immobilized enzymes in the lactose industry? Introduction Enzymes are protein molecules that act as catalysts (they speed up chemical reactions) in living organisms. Enzymes are specified, however, they are not permanently specified- they do not change from reactions, which allows them to be reused. Despite the fact that they can be reused, if enzymes are in a solution with their reactants, it is difficult to separate them. Without enzymes, the chemical reactions in our body would be too slow to keep us alive.
The first solution I found was limiting carbon emissions. By doing things that limit our carbon emissions such as carpooling or walking we will put less carbon dioxide into the atmosphere, creating less to find there way into the ocean. This would be the simplest solution to our problem, but I don’t believe people would be willing to do these simple things. Alternatively there is iron fertilization. By seeding the ocean with carbon we can absorb some of the excess carbon decreasing the overall amount.
There are several ways people tried to energize their bodies but the most efficient way to energize your body is by going natural. Now that few of us are able to dine of natural or herbal foods, things have been further made easier by manufacturing of supplements that entails all nutrients required by the body. This is why you need to get vega maca powder because the health benefits that you body could be missing. Although vegetables contain wonderful benefits for the body, there is little to be gained if one was to eat vegetables alone and that is why you need this supplement. What is Vega Maca Powder?
