Sipp Bay Experiments

It is okay if the periwinkles and dogwhelks move, just make sure they do not obstruct the test. The Actual Experiment: To begin the experiment, one must pick out one hermit crab at random from the holding bucket. One person records the data about the species of each hermit crab, the species of the shell it is dwelling in, and anything else of interest about the hermit crab itself regarding its appearance. The recorder then must prepare the stopwatch, as the collector places a hermit crab into the bucket

At the start of this experiment we were required to obtain a set of four Wisconsin Fast Plants, which are genetically, known as Brassica rapa. These plants have been, “originally selected under continuous fluorescent light to grow and reproduce quickly for research purposes, these petite, fast-growing plants have been used for teaching biology concepts” (Wisconsin Fast Plants). These four pots that contain our plants will be under our watch for the next 16 weeks where we will show our results at the end of the semester.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

The low-density radish-collard mix pots contained four seeds of radishes and four seeds of collards. The high-density radish-collard pots contained 32 seeds of each species. While our group replicated this 3x2 design four times to total 24 posts, we incorporated the whole class data. Therefore, there were 16 replicates for each treatment. For each pot, we filled soil up until about one inch from the top. We placed the seeds in the pot and piled on around 2 or 3 cm of soil on top. In 3 species levels, seeds were spaced as evenly as possible. In the mixed species pot, the two species were alternated so that each one had the same access to space and nutrients at the other. For each pot, we wrote down our section number, group name, and the contents of the pot. Our group worked at the first bench in the greenhouse and also contained our pots that were spread out evenly in four rows. Our pots stayed in the greenhouse for about five weeks, captured as much sunlight as they could, and got their water source from sprinklers that automatically came on twice a

Prior the conduction of this experiment, Sordaria of different ascus types (WT and T) were exposed to significant levels of radiation. There were three experimental groups for this experiment and crosses accordingly. Crosses were set up in containers by placing different Sordaria groups in alternating fourths of the mating agar. The Sordaria naturally grew outwards to the different adjacent Sordaria groups and inter-mated through meiosis. This provided a variety of different crosses throughout each experimental group. The squashes were prepared by obtaining a clear slide and placing a small amount of water in order to trap and spread out the perithecia. Once the individual perithecia were separated, they were busted by applying slight pressure with an eraser head, but done carefully enough not to pop the individual sacs. Frequencies were calculated by counting the number of

Apalachicola Bay is wide estuarine system located in Florida panhandle and covers an area about 539 km2 (Figure-1). The bay is relatively shallow with an average depth of 3.0 m. It is one of the most productive natural systems in North America and highly recognized by the state, federal and international organizations for its pristine water quality and unaffected estuarine habitats (ANERR, 2008). Apalachicola bay and its barrier islands were formed by deltaic processes of Apalachicola River, which is one the unpolluted alluvial system left in the United States. The bay is surrounded by four barrier islands, St. Vincent Island, Little St. George Island, St. George Island and Dog Island. The water exchange

The British Heart Foundation is the UK’s Number 1 Heart Charity. Their vision “is a world where people don’t die prematurely from heart disease.” They were founded in 1961 by a group of medical specialists who wanted to give money to fund extra research to find out the causes of heart diseases. They were concerned about the number of people with Cardiovascular Heart Disease who were dying prematurely. They have been going for 53 years and have been helping people since then. They have been taking part in all events but the main one which is coming up in September is the Oxford to Cambridge Bike Ride.

The plant material used in this experiment were marigolds. Planting the marigolds into six-pack cell containers, making the total plants used 54. Using three cell packs for every treatment mixture with third treatment being the controlled treatment, meaning that no material is added or taken from the solution. Treatment one was a mixture of miracle grow and perlite, what is perlite? Perlite is a lightweight particle that can hold up to four times its weight in water. The second treatment was a mixture of miracle grow with sand, leaving treatment three to be the controlled treatment which was just miracle grow.

All five groups recorded the outcomes that they established. For our bench, we found that nine raddish seeds in the control dish, zero raddish seeds in the eucalyptus dish, and four radish seeds in the lemon dish germinated and sprouted. Our bench also found that the average seed length for the control was thirty one millimeters, for the Eucalyptus was zero. and for the Lemon was eight and a half. Below, is a chart and graph that shows the whole data as averages from all five benches. Each bench did the exact same experiment so we knew nothing would be biased.

9. Precipitation plays an important role in the evolution of these finches. Low levels of precipitation results in plants that produce hard seeds. High levels of precipitation favor plants that produce smaller softer seeds. Medium levels of rain produce medium seeds. Click the New Expt button and then click the Change Inputs button. Click the Precipitation button. Notice the percentage distribution of hard seeds, medium seeds, and soft seeds as precipitation is changed. Finches with small beaks are better at utilizing soft seeds as a food source. Medium and hard seeds require larger beaks. Increase the annual precipitation on Darwin Island to 100.0 cm/year and Wallace Island to 10.0 cm/year. Now click on the Beak Size button and set the initial beak size on both islands to 20 mm. Click the Done button and Run Experiment button. Click the Beak Size tab and then the Population tab. Which of the following statements best describe what

Propaganda in general is the idea of getting others to believe in one’s own beliefs. Propaganda is the “attempt to influence behavior…by affecting through the use of mass media of communications, the manner in which a mass audience perceives and ascribes meaning to the material world.”1 Propaganda was a major part of Germany’s way to brain wash people into following Hitler and his army. The theme of Hitler and Goebbels, (Paul Joseph Goebbels, was appointed Hitler’s Reichspropagandaleiter, the Nazis national director of propaganda), using propaganda, “was to merge the traditional German patriotism with Nazi ideological motifs”2, this was basically used from1919 to 1945.

Introduction Accounting is divided into three major areas: financial accounting, managerial accounting and cost accounting. Each big organisation like the NHS has several costs and to ensure efficiency a breakdown of these is necessary. The breakdown will lead to indirect and direct costs. In this essay we are going to look at managerial accounting inside of the NHS.

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

The ability of an organism to surviveal in a changing and unpredictable environment is largely related to its phenotypic plasticity. Overall, this concept is defined as the ability of a single genotype to manifest a range of phenotypes in response to variations in the environment [1, 2], and it is often considered adaptive because can increase individual fitness [1, 2, 3]. Plasticity embraces not only the flexibility in morphological traits, but also in behavior, life history, physiology, biochemistry, and virtually any trait [1, 2]. Behavioral flexibility is a crucial component of the phenotypic plasticity that allow that individuals change the types and amount of behaviors in space and time, according to the environment pressures [1, 2, 4].

The goal of this study is to test whether captive enrichment affects the reproduction success of P. promelas.
