BEAN LAB
BEAN LAB

My hypothesis was the white beans would stand out but the black and green beans would be camouflage. For my prediction I said that if the predator consumes more white beans than black. Therefor, the white bean population will decrease. In the “beetles” environment the predominant colors are brown, green, black and tan; and the predominant colors for beans being brown, black, green and white. Knowing the predominant colors of the environment and of the “beetles” would show that the white color in the species would stand out and be selected against in natural selection. The other “beetles” have similar colors to there environment and would be selected to survive. Pinto and black beans were the two victims of natural selection that were closer to a median than anything else. This was because of the shade and color of there outer shell. The light shaded beetles were easy prey since they had nowhere to hide from predators. The green beetles had plenty of places to stay camouflage and blend in with the environment. This is why green was the strongest survivor and stayed most hidden and safe out of the entire species. In the final test green beetles produced more than twice as much offspring as the most preyed upon beetle (the white beetle). In the lab we were either the predator or the prey. One being the prey spreading the “beetles” around In there “habitat” and waiting for the predator to hunt the beetles.
Cryptic coloration plays an extremely large role in natural selection. One of the best survival genes because of how the animal can blend in with there surroundings and there environment. Predators have a difficult time spotting there prey if there prey is one with a habitat they have adapted to camouflage in.
Natural selection can change populations and traits juristically in any species. Especially when you look back at some of the predominant colors and the prey that was selected for and against in this lab. How white had the lesser advantage and how

    The purpose of this lab was determining the effect of surface area on the beets ability to interact with the environment. Three similar sizes of beets were assigned. Each beat was cut up into different sizes as one large piece, two smaller pieces and eight tiny pieces. All three different slices of beets were placed in their own containers and tested.…

    This lab was testing different methods to prevent bean beetles form infesting a chickpea harvest. They wanted to find something that would protect the crop from this invasive creature. To do this they created 3 replicate experiments which contained 25g of seeds each group with a different genotype, and 5 newly hatched adult C. maculatus were added to the jar. They continued to check this on a weekly basis, at the end of the experiment they found that the results where quite different for each jar, and that all of them were not immune to the bean beetle.…

    What are the factors that lead to evolutionary change? Using mathematical equations, Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population. The Hardy-Weinberg equation can be used to describe the allele frequencies in populations that are not changing evolutionarily – and also can be used to determine if populations are changing over time.…

    The purpose of the research was to formulate a question and develop a hypothesis based on the variations observed between two populations of threespine stickleback, in order to gain a better understanding of natural selection and evolution. Measurements were taken of the number of scutes, ventral length and standard length in Population A. Population B data was provided by instructor. Four null hypotheses were formed on each of the measurements taken, the last hypothesis being no difference between populations. Data was collected from classmates and then compiled together into an excel spreadsheet. Using the spreadsheet, determined confidences intervals and looked for overlapping in the populations. From the confidence interval, it was concluded that there was a significant change between the populations. All of the hypotheses were rejected except for one. Thus proving phenotypic variation and natural selection occurred.…

    We created a small reservoir for this experiment to take place using petri dishes. We used brown paper as a dark side of a petri dish and a whit sheet for the light side. We placed the planarians in the middle of the white petri dish for our trials. in the end of the experiment we found out that more planarians went to the dark side instead of remaining in the white side. From the research I have done on platyhelminthes I concluded that the results came to be by natural selection, and how organisms camouflage themselves to hide from predators by blending in with there surroundings. This idea is supported in the observations I made because since the planarians were darkly colored they moved to a spot with more dark colors instead of being in a place with no color(the white side) and being very visible. My hypothesis, If the Planaria are placed on the white side then they will move to the dark side, was supported in this experiment. it was supported because the majority of planaria moved to the dark side instead of staying in the white side. Even though we made few errors in our project, our results should not be changed so much. If I could have changed the experiment in one way, I would have chosen to use a stopwatch instead of a analog clock to keep the time. I believe my partners in the grouped participated in the experiment equally. I also believe that each person did the same…

    Both the Pocket Mouse and the Peppered Moth’s environment changed in color from light to dark from a major environmental impact, causing both species to adapt. The best fit organism for the environment at the time continued to reproduce until their color changed over time, and adapted to become better camouflaged from predators. The Peppered Moth and the Pocket Mouse both carry the genetic mutations of a dark color allele in the gene pool as opposed to only a light colored allele, which is the reason natural selection was able to occur and this adaptation affected the population in that specific…

    Based on the knowledge I gained from the blubber lab, I discovered how homeostasis is maintained by feedback loops in regards to blubber. A negative feedback loop is a process where change is prevented and a certain set point is kept. In this experiment, the negative feedback loop was the blubber preventing the changing temperature of the thermometer. Therefore, blubber is a method of homeostasis, because it prevents the ideal temperature of the thermometer from dropping. Our data shows this as well. When we used Jello, cornstarch, and aluminum foil, it kept our thermometer’s internal temperature 20 degrees higher than the ice’s temperature of 0 degrees Celsius. Although a lower temperature, it was the same results with negative feedback loops…

    The peppered is a very good example of natural selection because there is already black moths in the population, but the peppered survived better before the industrial revolution.Though when the industrial revolution comes in the lichens on the trees die and the peppered moth begins to be eaten more by birds and black moths survive and become more common. This shows that the variation in the population helps because if the moths didn't have variation and were all peppered they would have all eventually died out. Natural selection made the colors of moths change to black during the industrial revolution.…

    A key concept in evolutionary biology is that divergent selective regime will often generate and maintain some type of phenotypic diversity (Langerhans et al. 2003). This divergent selection can lead to differences in phenotypic expression either by a genetic differentiation or phenotypic plasticity (Levins, 1968; West-Eberhard, 1989: Robinson and Wilson, 1994; Orr and Smith, 1998; Schluter, 2000; cited in Langerhans, 2003). Such divergence is significant as it can influence microevolutionary changes and result in speciation (West-Eberhard, 1989).…
