Brown Bunnies Lab

The purpose of this experiment was to determine if cats have a color preference. I wanted to do this experiment because I took an interest in my cat’s vision. My hypothesis was that my cat would prefer the color blue. I used 5 different colored balls of yarn. They were placed in the same spots and sequence each time. I conducted this experiment for a total of four-weeks. I set my cat up behind a line of painter’s tape and let her approach a yarn ball and play with it. I recorded how many times she approached each color. At the end of the experiment I discovered that my hypothesis was not supported. My cat chose to play with the yarn colored black rather than

Potential error could result in when quantitatively transferring in any step and spillinng or not transferring all of any given solution. When diluting each flask has a different level for where its specific volume is, so overfilling the flask is possible when not being focused on. The condition of each penny can impact the results by if some copper was chipped off, or if anything attached to the pennies could impact test results. All of these could result in a different than desired copper percentage. It is important that the absorbance of each penny be within the range of absorbance the calibration curve has. This is because the curve created for this lab was made with 0.00 – 10.00mL of Cu^(2+)stock solution when using those values idealy this curve should therefore be 0-100% copper percentage. If values were found outside of this calibration curve then there would be problems with either calculations or a different curve would be needed to properly record

A Doodle is a cross between a Poodle and another dog breed, with over 150 dog breeds, choosing the perfect family pet can be onerous. When picking a pet, there are so many factors to consider such as

Evolution of the Rabbit Population with Default Predation and an Initial Decrease in the Grass Rate

What observations can you make about the genetic variation between the parent and founding populations?

The results of the allele frequency changes in the five different trials are all in close range of one another. The trials 1 and 5 being the same at .85 and were the highest, trial 4 was the lowest at .70, and the two middle results were trial 2 at .75 and trial 3 at .80. In a population size of 1000, the difference in the green and albino alligator’s pigments will inevitably affect the fitness. The green alligator is the dominant big “A” allele, while the

The reason for doing this lab is to study evolution using small population of finches on two different islands. I used different charts and graphs to find limitations on natural selection. Then find the effect evolution will have on beak and population over a certain time period. Using three different assignments I have to develop different hypothesis comparing and contrasting the average beak size and population size changing rain fall, beak sizes, population and island size on Darwin’s and Wallace experiments.

To stay consistent with and avoid error, the number of changing variables will be as close to 1 as possible; the only variable being externally manipulated in this experiment would be bean beetle size in two of the populations. (I.E: One group is a random control group of 10 beetles, one group is a variable group with the 10 smallest size beetles, and one groups is a variable group with the 10 largest size beetles.)

In order to test my hypothesis, eight separate plots containing a certain amount of Simploids and plants were used. A total of four plots were utilized as the experimental group, in order to conduct the analysis and test the effects of parasites on the health of the Simploids. The remaining four plots were used as the control group, where they resembled the experimental groups in terms of sample size but received no exposure to parasites. Thus, the four experimental plots that were infested with parasites were each given a sample size of fifty Samploids and fifty plants. This was done as a form of replication in an attempt to identify if there were any outside factors that could be contributing to a change in the Samploids’ health. Thus the control group was composed of the same variables as the experimental group with the exception of parasite exposure.

An experiment was done to determine the concentration of Allura Red in a commercially available beverage, Gatorade. This was done by using the colorimeter, the absorbance of five Allura Red solutions were measured. The graph obtained demonstrated a linear relationship and the equation obtained yielded a concentration of 1.9910-6M.

Cutting through the mink to study its anatomy helps the group to realize that they are similar to human. The most important tools used in the lab are scissor, probe, pins, tweezer, and scapula. The most tool being used is scapula which is used to cut up the mink and skin it. Safety materials are required in the lab in order to avoid accident. Since the minks contain cancerous chemicals on them, the classes are required to wear safety goggles, apron, and gloves. The class started the dissection from May 18th to May 27th in third period of Anatomy class.

The purpose of this lab is to better understand the process of natural selection and its effects on a population by conducting a stimulation. The stimulation consist of predators (students with either a spoon, fork or a knife) and prey (different types of beans). Furthermore, students will be able to determine how phenotype (bean color and utensil used by the predators) influences natural selection. Students will also demonstrate their quantitative skills by determining the predator survival and reproduction, bean survival and reproduction, and by calculating the total percent of the population. Additionally, students will be able to identify the occurrence of evolution by natural selection after the end of generation three. Moreover, students

This experiment is relevant because scientists have the ability to analyze situation where they gather information about color preference in organisms and how it is driven. The color preference for a guppie plays a role in natural selection as explained above, as well as sexual selection. With this information, scientists today are able to observe natural selection today and how it is always in effect. Although humans are not able to see the exact natural selection take place

“If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing environment” (O’Neil, 1998-2013). Scientists call this reproductive success. “Within a specific environment context, one genotype will be better than another genotype in survival or reproduction for certain reasons having to do with the way its particular features relate to the environment or relate to other organisms within the population” (Futuyma, 2000-2014). The theory of evolution is explicable through various kinds of scientific research.

There is no other breed like the Pug. Not only does he look distinctive, but he has a character like no other. His furrowed brow may make him appear perpetually worried, but beneath the wrinkles lies a happy-go-lucky dog with a clown-like personality.
