Download file to see previous pages One particular animal, which gained Darwin’s attention, was the finches on the island. It was through studying these finches that Darwin came up with one of the most important terms in evolutionary biology which is one of the driving forces for evolution: natural selection. Natural selection plays into the role that nature selects organisms, which are best fit for the environment. Those that have the traits that give them the best advantage in environmental conditions will survive and proliferate while those who have the inferior traits will not thrive and die out (Darwin, 2010). In this particular simulation, we were looking at what the effects of precipitation on two separate islands and how it would affect the size of the beak on a species of finches. We are able to make this hypothesis due to the fact that we know that the amount of precipitation will influence the different types of flora and seeds, which will grow on the island. This can affect size, hardness, and shape of the seeds and this will have a direct effect upon the size of the beak of the finch that inhabits the island. Our hypothesis was that of non-directionality, meaning that we did not know how precipitation was going to affect beak size in any particular direction, but we knew that the precipitation was going to have an effect on how flora grew on the island, thus this would have an effect on beak size. Materials Since this was an interactive simulation, very few materials were needed in order to complete this lab. A computer with an active Internet connection was necessary in order to use the online simulation software in order to collect the data, due to the fact that this observational data would be impossible to be collected over the thousands of years. Methods The first step of being able to run the experiment was to log onto the site in order to carry out the experiment at http://www.biologylabsonline.com/axia/EvolutionLab/. Next, depending on the experiment, the experimenter has the option to set the variables that they are interested in looking at. For the case of our hypothesis, we are looking at beak size in relation to precipitation. The independent variable is the initial size of the beaks. The experiment calls for modifying the precipitation on the islands in order to see if this has an effect on beak size. On one island, move the precipitation to the extreme of there is no precipitation and then on the other island, move the precipitation to the maximum amount of precipitation the island can have. Set the amount of time to look at over the course of three hundred years and run the experiment. Then look at and analyze the data to see if the data matches the proposed hypothesis. Data Parameter DARWIN WALLACE ------------------------------------------- Initial Beak Size: 12.0 mm 12.0 mm Heritability: 0.7 0.7 Variance: 1.0 1.0 Clutch Size: 10.0 eggs 10.0 eggs Precipitation: 35.0 cm 20.0 cm Population: 200.0 birds 200.0 birds Island Size: 0.5 km 0.5 km Darwin ------ Wallace ------- Discussion and Results As can be seen from the graph, we have an interaction effect at the start and then both populations diverge from each other as time progresses. On Darwin Island, where the precipitation was observed to be 100.0 cm, there was an increase in beak size as time increased. On Wallace Island, where the precipitation was observed to be 0.0 cm, there was a decrease in beak size as time increased. Based on this result, we can conclude that over the 300-year ...Download file to see next pagesRead More

... Procedure This experiment requires three cuvettes, a spectrophotometer, a graduated cylinder, dye of three differentcolours. The first step is to fill the three cuvettes with red dye, green dye and blue dye with each holding a dye of different colour. The initial concentrations of these dye is 100% at the beginning of the experiment. The cuvettes are then placed into a spectrophotometer. They are oriented in such a way that their smooth sides lining face the light source to enable easy penetration of light through them. Multiple trials were then performed because the spectrophotometer can only measure one sample at a time. In order to ensure accuracy and precision, it was necessary to re-calibrate the spectrophotometer three... Procedure...

The “tree of life” is a phylogenetic illustration of the origin of the various species of animals from an ancient single organism dating from millions of years. It shows the location of every animal in advancement relative to other organisms and relative to the original ancestral organisms (Evolution and Natural Selection, 2010). Q2.

It represents a critical analysis of experiments on the effects of certain variables on finches living on these two islands. The central focus of these experiments was to hypothesize that precipitation, size of the land and diet among other variables play an important role in evolution of living organisms. With different controlled environments, the experiment targets to note the difference in the size of beaks and difference in population over a period of 100, 200 or 300 years. The major...

...Experiment #3 — observing the Moon’s Phases Objective To determine the relationship of the Earth, Moon and Sun as the Moon orbits the Earth. Introduction In astronomy, determining the relative position of the moon, the sun and the Earth requires the study of phases of the moon at different days of observation. In which case, complete cycle through the phases called lunar month gives the synodic month, always around 29 days. The lab report studied these phenomena to realize moon’s position in relation to the other two. Procedure The moon was observed and a dark part was shaded to show how the moon would look like at each point from the Earth. Each phases of the moon was labeled and presented in diagram forms as shown in...

On the other hand, the temperatures for oil output, the exhaust, cooler in the engine, the cooler output and the oil input decrease with time. The results recorded were used to calculate for the derived values such that torque was obtained as 72.7 N/M and ranges between 72.1 N/M - 72.7 N/M, the brake power was obtained to be in the range 40987.46667 KW - 8370.193333 KW, the brake thermal efficiency was calculated to be 32% and ranges between 23.4 % - 32.4 %.

One of the importantconcepts for this experiment is solubility, which can be defined as the ability of a substance (solute) to dissolve in another (solvent) (Bauer et al. 216). The estimation maximum quantity of a substance that dissolves in a solvent at equilibrium yields solubility (Brown et al. 120). Qualitative analysis is done to identify elements in the sample used for the experiment. For this experiment, qualitative analysis was employed to establish whether or not a precipitate would form upon adding some acids and bases. A flow chart was used to distinguish between cations in the resultant solution. A flow...
