3. Compare the Biuret test results of albumin and pepsin, the Benedicts, and starch results for potatoes and onions, and describe how one can determine the relative amounts of sugars present in a sample using the Benedicts test.…
In the Kingdom Exploration lab, five different organisms were observed under a microscope, (Yeast, Paramecium, Elodea, Daphnia, Euglena). Each of these organisms is apart of one of the six kingdoms, (Eubacteria, Archaebacteria, Fungi, Protista, Plantae, and Animalia) which are apart of three domains, (Archaea, Bacteria, and Eukarya). In this lab, however, none of the organisms observed were archaea or bacteria. Also, all the organisms were eukaryotes, not prokaryotes, which are organisms without a nucleus and a single chromosome (a double-stranded DNA located in an area of the cell) instead. In the lab, organism one is a very small dark green leaf from a small plant. Under the microscope, there is a lot of chlorophyll, floating around inside the rectangular cells. Organism one…

A. Create a solubility curve for NH4Cl by plotting g NH4Cl/100 mL H20 on the y-axis, and crystallization temperature on the x-axis. Make sure to label each axis. On the same graph as the solubility curve for NH4Cl, add the solubility curve for NaCl using the data provided in Data Table 3.…
r 1. Name two types of sickness you can get from phytoplankton in Florida, and describe how you can get them. What symptoms led to the diagnosis of our patients? Some of the major diseases are NSP, and PSP which typically come from Brevetoxins, Saxitoxins, Gonyautoxins, & many more. The typical symptoms includerespiratory distress, allergic reactions and skin conditions…
In the BIO 14 Lab, the organismal system used for the last of three labs this semester is the Mimosa pudica plant. In these three weeks the stimulus-response of these plants will used to conduct experiments on the phenotypic plasticity of Mimosa pudica. Phenotypic plasticity is the ability of an organism to change its phenotypic traits in response to changes in the environment. And while very beneficial in some ways such as by allowing organisms to adapt to a changing environment quickly, it also has its costs. The greatest cost probably comes in the energy the organism needs to expend in order to produce the changed trait. For example, in the phototropic effect in plants, the plant bends toward the sunlight to allow for more of its leaves to get direct…
My hypothesis is if the water temperature is hot then the life saver will dissolve quicker because the hot water has a greater chemical effect on the life saver than the other temperatures. I believe this is because the hot water is creating a chemical change and is changing the solid object into a liquid.…
Patterns of plant successional change in Gatineau Park, Old Chelsea, were studied quantitatively. The relations between different successional stages of plant communities and abiotic factors were descried. To test these, we went to the fields, and worked on two transect in groups of 4. We counted the trees and measured the diameter at breast height (dbh) for tree with a dbh value greater than 2cm. The dbh measurements (cm), percentage of fern cover and percentage of bare ground were recorded and used to perform statistical analysis. No significant variations in the distribution of abundant tree species using chi2 analysis and percentage of fern cover using t-test analysis were observed between the compared sites. No significant variations found in the interquadrat analysis, and mean dbh of abundant tree species and percentage of bare ground between the sites compared. The results verified the stated hypothesis and were supported by literature sources.…

A biome is a large, distinctive, complex community of plants and animals in a region maintained by climate. There are different types of biomes including tundra, taiga, deciduous forest, scrub forest, grasslands, desert and rain forest. Scientists disagree on the exact number of biomes in the world.…

The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population, and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining life, when changing the beak size to a much larger size we will see that the finch will have no need for further evolution of its beak and that its population will become much more stable and consistent throughout the years.…
