Discussion The purpose of the paramecium study was to observe how two species, P. aurelia and P. caudatum, interacted with each other. Could the two species coexist? Or would one dominate the other. Twice daily for two weeks each ecology lab sections counted the paramecium stock. Each section observed and counted P. aurelia and P. caudatum that were alone and in competition with each other. The raw data was collected, recorded on a master list, and the results were calculated and compiled. When two species are competing for the same resource only one of them will survive, while if they are without competition each will grow and survive. This theory dates back to the early 1900’s when G.F. Gause conducted the experiment. Figures 1,2, and 3 represent the average densities over two weeks when …show more content…
One way to allow two competing species to coexist are endosymbionts. “Endosymbionts are smaller symbiotic partners living inside a host organism, establishing endosymbiosis. The symbionts may live within the host's cells (intracellular) or outside cells (extracellular).” (Jeon 2011) According to Johann Muller, “Endosymbionts can thus mediate the coexistence of the two competitors for the same resource by providing a supplementary resource to its host. “(Muller 2012) When Johann Muller conducted the experiment, the two species were competing. P. bursaria with endosymbiont and a competitor were grown together. The endosymbiont supplied necessary nutrients that allowed P. bursaria to survive when it should have been out competed. The importance of this showed that other factors could influence how two competing species can coexist. If endosymbionts were mixed into the competing P. aurelia and P. caudatum stocks for the ecology lab experiment, the results could have shown a coexisting relationship between the

The protein molecules in many foods provide the amino acid building blocks required by our own cells to produce new proteins. To determine whether a sample contains protein, a reagent called Biuret solution is used. Biuret solution contains copper ions. However, the chemical state of the copper ions in Biuret solution causes them to form a chemical complex with the peptide bonds between amino acids (when present), changing the color of the solution. Biuret solution is normally blue, but changes to pink when short peptides are present and to violet when long polypeptides are present.
Please answer these questions then place them in the drop box for this lab. Use Microsoft word if possible.
When the pH is not at its optimum, the differing pH's will disrupt the bonding between the R groups of the amino acid causing its structure and the shape of the activation site to change
A1.Work under the hood! With a pair of tongs, hold a strip of magnesium in a bunsen burner flame. Do not look directly at the flame. Save the ash in a small beaker for the next procedure. If magnesium is substance "A" in the general equation, what is "B"?
1. When you are notified that a user’s workstation or system is acting strangely and log files indicate system compromise, what is the first thing you should do to the workstation or system and why?
Table 1 Concentration of protein, DNA, and ratio of the two in heart, kidney and liver of bos taurus. Average standard deviation of protein concentration is also shown.
3. Experiment: Use the Gizmo to find the carrying capacity with Ample, Moderate, and Little land. List the carrying capacities below.
Different characteristics of species allows for the types of niches that can be occupied and whether or not they can be coexisted for example a food specialist will have anatomical and physiological adaptations that allow it to acquire and extract energy and nutrients from one food source extremely well, but will be at a disadvantage if that food source runs low. A food generalist may not acquire as much energy from the specialist’s preferred food, but will be able to make up for that by consuming other kinds of food. We can easily envision circumstances in which either species might outcompete the other. To achieve coexistence of species the carrying capacities of certain species must not be overshot and remain
Paragraph 1 - How the Law of Conservation of Matter is supported by the experimental demonstrations: In the law of conservation particles and materials are neither created nor destroyed . It was similar towards the experimental demonstrations because nothing changed or destroyed in the processes .Kinetic and potential energy was used in the experiments.
Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction.
A particular question that is seldom pondered over and yet is capable of carrying so many doubts within it: who are we? Who are we as a society who can do the things we do? Who are we who can suffer from them? Award winning poet and essayist Susan Griffin confronts these distinct questions in her work titled, “Our Secret”. Griffin believes that a basic understanding of the things that play a part in the growth of an individual is essential to understanding who we are. The way a child is raised dictates how that child is going to become later on in life. One of the distinct highlights of Griffin’s essay was her use of describing the progress of the V1 rockets in World War II. Griffin studies the aspects of human nature by using these missile developments as a metaphor to symbolize the raising of children and the factors that can influence a growing individual. One of the prime figures that Griffin uses pertaining to these growing individuals was Heinrich Himmler, leader of the Nazi secret police. Griffin uses Himmler as an example to demonstrate how big of a role a parental figure can play in the development of a person.
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.
