Red Colored Prey Hypothesis

818 Words4 Pages

Hypothesis #1: In environment one, it was hypothesised that the light and dark blue prey will have the highest survival rate. This is because their colors will blend in with the fabric, making it hard for the predators to find them. #2: In environment two, it was hypothesised that the pink, white, and black prey would have the most left over when the predators finished. This hypothesis was also inferred because the color of these prey would make it easier to blend in with the fabric. Data Analysis: See attached Discussion The hypothesis that the light and dark blue prey will survive because their colors will blend in with the fabric, making it hard for the predators to find them was rejected as shown by the data. The data showed that red colored prey had the highest number of survivors followed by the green prey. The red colored prey was 32% of the population, followed by green with 24%. Other colors such as yellow, dark blue, …show more content…

This meant that in the population there were already ten different color of prey that occurred naturally. However, when the environment was a blue background with colorful flowers and butterflies, many of the different colored prey had gone extinct and the red prey had the highest number of survivors. Also, environment two was pink, white, and black plaid and the prey that had the most number of survivors in that environment was white. This demonstrates that depending on the environment, different variations of a trait would be successful. It also demonstrates that the adaptations in this experiment depended on the environments. In these environments, the percentage of surviving colored prey would be different. The prey have already adapted their colors to their own environments to camouflage and survive. However, other environments can be different colors, so the prey that can camouflage in one environment will not be able to do the same in

In general, all the predators and prey (regardless of habitat) began with the same amount of population. For instance, there are a total of six predators (2 had forks, 2 had spoons, and 2 had knives)—regardless of habitat, Meaning each predator contributed to 33% of the population (Tables 1A, 2A). For prey, each bean contributed 25% of the population (Tables 1B, 2B). However, as generation progressed, differences began to appear.

The χ2 value was 0.012858, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact reliable. In Trial 3, twelve isopods (60%) made the choices of hiding behind the sucrose sponge. The χ2 value was 0.00350342, df was 3 and hence the P value was in between

After putting my organisms in an environment, the organisms with the color that best blended with the environment’s color would increase in numbers. Whereas, organisms with a dissimilar or opposite color to the environment would die-off over time. The reason why organisms that could better blend in with the environment flourished, while the organisms who stood out in the environment died is because of natural selection. The organism that could better blend in would be harder for predators to find, thus increasing its chances of living and reproducing. While the organisms that stood out would have a higher chance of being eaten or

Along with this, Marsden also discusses the concept of environmental degradation through the quote “The land is bare and brown and the wind blows empty across the plains.” Throughout the book, the audience sees bright and saturated colours before the rabbits came, but as they slowly colonise the marsupials the colour scheme grows monochrome with greys. This visually impacts the us to feel sad for the marsupials as they see how FNP have been affected by

The data collected from previous classes had a total of 77 owl pellets that were dissected. Out of the 77 total of owl pellets that were examined, a total of 137 rodents skulls were found in the owl pellets compared to a total of 32 nonrodent skulls that were uncovered in the owl pellet. The data in Figure 1, demonstrates the average total number of rodent skulls compared to average nonrodent skulls found in the final spreadsheet from the total number of owl pellets dissected in each class. On average, the amount of rodent skull prey caught is 1.80 in an owl pellet in a night compared to 0.42 nonrodent prey skulls found in an owl

The results of the male mating success calculations however, were consistent with the prediction that selection would occur against white-eyed males in the light condition, but not in the dark condition. Results of viability calculations, white allele frequency over time, variance over time, and heterozygosity over time, were all inconsistent with predictions made. There was no statistically significant difference found between the viability of white and red flies in either lighting conditions, a result that was expected for the light condition but not for the dark condition, where selection was expected to occur against the white allele and decrease viability compared to wild-type males. The average allele frequencies behaved as predicted for the light treatment populations, showing a decrease in white allele frequency, most likely due to selection against the allele. The small/dark population also behaved as predicted, showing an increase in allele frequency, but the large/dark population showed an average decrease in allele frequency.

In this natural selection and genetics lab, a pair of alleles was randomly chosen from a cup of 100 alleles. There were 50 dominant and 50 recessive alleles. A pair of alleles was chosen randomly from the cup. The first time this was done all the organisms survived. The second time this was done the organisms that were homozygous recessive died due to the lack of an enzyme needed to digest grain.

I conducted a lab that would investigate the question of whether or not camouflage favored natural selection. If an animal blended into its surroundings, I wanted to know if it could more effectively evade predators and survive as a species. I hypothesized that if I were a predatory bird hunting for mice in a field, then the mice that were camouflaged with their environment would be harder to find. The results did not support my hypothesis, as most of the mice (often more than 2/3) that had a similar appearance to the field they lived in were hunted, and did not escape predators. You can determine if a predatory bird would have more difficulty finding mice that were camouflaged with their environment.

Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.

Color for Tayo’s people (Laguna) was extremely important. Yellow, blue and white appear in the ceremonies performed by Ku'oosh, Betonie, and Ts’eh, but also in nature. On his healing journey, Tayo eats blue cornmeal and Betonie the medicine man paints yellow, blue and white bear tracks on the ground. Ts'eh uses all three colors as well when she pairs stones and plants.

It is clear from the illustrations that the story involves a more powerful being than we are used to seeing. What color does the illustration use? Eric Carle uses the collage technique to create bright and cheerful images, using hand-painted papers, which he cuts and layers form bright and cheerful images. Caterpillar colors such as green, brown, orange, yellow, or black are ideal for camouflage. They help caterpillars blend into their natural habitat, the leaves and plants they feed on.

For example, The Red Queen is easily associated with red, gold, and white, and yet the beast that goes after Alice from 1:29-1:35 is mainly white with black spots. Oddly enough, after the White Queen is enters the trailer and the battle scenes begin, the beast that once chased Alice is now on the White Queen’s side, seen in the background beside the white chess headed soldiers at 1:49. The audience is not preoccupied by the color schemes presented in this scene but are preoccupied by what the characters are doing.

There is no doubt that they have a strong impact on psychological and physiological well-being. We cannot assume that the only role of light and color is to provide tolerable lighting and a pleasant environment. Although color vision does not appear in animal life forms, radiative energy and its spectral component still provide various psychological processes in each type of organism. For example: radiant energy is apparently vital to plant growth (Mahanke, F, 1993). Color quantity should

The objective is to determine foraging preference of ants by observing and measuring their selection between three different sugar concentrated solutions (5%, 15%, and 30%). The hypothesis is that ants prefer high sugar concentrated solutions than low sugar concentrated solutions. The prediction is that most ants will prefer high concentrated solution (30%) than the less concentrated solution
