Synopsis of the case This case is based on the issues faced by TFI Food Equipment Solutions. Alex Pettes, who is the new president of privately owned industrial distributor (TFI). TFI is renowned supplier in Ontario and its head office is in Brampton. Alex is concerned about the national market for two new product lines; revolver by one-shot corporation and French fry machine by R-O International’s automatic respectively.…
The objective of the Isopods Lab was to figure out if the Pillbugs favored the wet environment or a dry environment. After reading the pre-lab report on Pillbugs, my hypothesis was that “If water is added to an Isopods environment, then the isopods will favor the wet environment.” By using two groups of Isopods, one group was put into a dry environment and the other had one drop of water into their dish. After ten minutes of observing the Isopods, the results showed that the Pill Bugs prefer the wet environment more. As time went on, the bugs in the wet environment survived longer than the Isopod in the dry environment.…
Analysis: There are several instances where the number of pillbugs in the light are equal to the number of pillbugs in the dark. It’s difficult to decipher a pattern in the data. The pillbugs seem very indecisive and continuously move between chambers. However, if one disregards the data where the number in light and dark are equal, there are three times where the amount in light is higher and only two times where the amount in dark is higher.…
The top cover of the petri dish was put back on and the planarian was put back into the cabinet. The shocking process was conducted 5 days a week and once per day. However, the feeding process was either 2 or 3 times a week and it was also done once per day. A month after testing the planarian, it was time for it to be cut and regenerated to see which half would respond to the flash of light. There had to be a way to cleanly slice the planarian in half so it could perfectly section of the head and tail section.…
Once the egg was decalcified, it felt very fragile and bouncy. When the egg didn’t have a shell anymore, it was kept from seeping out by the “plasma membrane” (egg white), which was congealed by the soaking in vinegar. When the nucleus of the egg became visible, it looked very cloudy. The substance that entered/left the egg in each situation was water, due to the state of the egg, by way of osmosis, in a way of trying to balance the inside and outside the “cell” (egg), this balance is essential to functioning at the preferred isotonic state. This lab could be improved by using 2 different eggs, as the data seemed inaccurate when placing a hypotonic egg into a solution of corn syrup made the egg hypertonic, because there wasn’t a proper start weight in the egg when placed in the second solution.…
In order to collect accurate data from an experiment, it is important to evaluate the environment that the lab will be taking pace. While my lab partners and I were doing this, we checked to see if the workspace is clean and clear of an unnecessary or harmful objects, especially food. Then our second step was to gather all the necessary supplies for the experiment. This included, a microscope, three glass microslides, alcohol, caffeine, and water, four pippets, then finally three water fleas.…
1. Write a narration of the figure describing the results of the experiment. Explain why the rabbits are emaciated in groups 1 and 2. (Please note: What Dr. Trudeau called Experiments 1, 2, and 3 are more like what modern scientists would call treatment groups 1, 2, and 3, and that terminology is used in Figure 1. • Based on Figure 1 survival graph, the rabbit in treatment group 1 which was artificially infected, and placed in a controlled environment is thin. Also, on the third month of the experiment, there is only one rabbit left out of the five rabbits in this group.…

Examined T. californicus ability to handle high temperature stress under short-term, small exposure to high temperature, and long-term, persistant exposure to constant high temperatures. The took populations of T. californicus from 11 pools at different latitudinal gradients in a local scale. They put the specimen in petri dishes with founding adult females. They only mate one time and store the sperm so they can produce many groups of offspring. To test if inbreeding could influence the patterns of thermal tolerance they crossed independent lineages of the same population so they could use the offspring in thermal tolerance experiments.…
1.The increase in salinity is the main cause because of the problems of the faraway locations and because of the local cities waste that runoffs causing an accumulation of nutrients leading to salinity and even eutrophication. Which has caused deaths of fish and birds. As well as embryo defects to the fish residents of the Salton Sea. Making the Salton Sea a death trap instead of a safe substitution of the past wetlands. 2.…
This last month, in AP Biology, the class completed the dissection of a starfish, followed by a crayfish. With the experience of these labs, comparisons can be made between many aspects of these two organisms. These aspects suited for comparison include the body plans and symmetry of starfish and crayfish, the science behind their need and ability to move, how each organism obtains oxygen and distributes it therefore throughout the body, the processes of their digestive and nervous system, and lastly how each organism reproduces and the pros and cons of their methods. Starfish are classified among the phylum Echinodermata and are an invertebrate with radial symmetry and an internal skeleton with hard external spines. They have five arms, their…

Throughout the past 2 months I have been working on a project in which I breed flies. The traits of the flies I had been assigned were winged female and apterus male. To begin the project I started out with winged females to breed at least 8 virgin to then cross them with the apterus male. Apterus means to not have wings. Throughout the rest of the project I observed how an expected outcome can vary greatly from an observed outcome,…
Finally, the process was repeated as the zebrafish was going through its different stages. As a result, the stages and the in-depth descriptions were produced along with photographs and drawings to easily distinguish between the different…
