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. As shown on the graph,…

Hardy-Weinberg Equilibrium and Natural Selection Lab Introduction In this lab we were able to experiment to better understand the concepts of Hardy-Weinberg Equilibrium and Natural Selection. The theory of Evolution states that populations that are evolving will have allele and genotype frequencies that change from generation to generation. To evaluate whether a population is evolving, the Hardy-Weinberg equation is used. A population is in Hardy-Weinberg equilibrium if there is no change in the…

Exploring Bacterial Transformation Ian Nall BIO 181 | Section #73116 | Wednesday 1:30-4:15pm Abstract This experiment was designed to test the properties of bacterial transformation. The bacteria used was E. coli, the protein being added to it is called Green Fluorescent Protein or GFP from a jellyfish the Aequorea victoria. The GFP, in the form of a plasmid called pGLO, was added to a sample of E. coli and a control was created of E. coli without it. The E. coli was then placed…

increasing from 29.5 ± 0.2% (kanamycin-only) to 78.2 ± 1.3% (kanamycin/rifampicin combination). All the spray-dried powders were noncrystalline. The combination powder was stable at 15% and 53% RH and 25 ± 2°C during one-month storage in an open Petri dish and non-toxic (max concentration tested 50 µg/mL) to human alveolar and bronchial cell-lines. Surface enrichment of kanamycin by hydrophobic rifampicin improves aerosolization. Improved aerosolization may help to combat drug-resistant local…

Resistance of Ordinary Bacteria to Penicillin Russell, Bradley BSC111L 4 Nov. 2016 Introduction Antibiotic resistance is a problem that is occurring more and more rapidly across the world. Antibiotic resistance is when antibiotics have lost the ability to control or kill bacteria. The bacteria become resistant to antibiotics and continue to multiply. This is causing medical and science communities to grow more and more uneasy as therapeutic levels of antibiotics are becoming less and…

Since the beginning of time, Staphylococcus, also known as staph infection, has (Khan, 2017), but there was not an official discovery of what it was until much later. In the year of 1880, a surgeon discovered the bacterial infection in a patient after a surgery (Mandal, 2012). A staph infection is an infection caused by a group of Staphylococcus bacteria that can cause many different conditions and diseases. Believe it or not, the Staphylococcus bacteria is found in the normal flora of the body…

The factors that we are able to control are things like the salt water concentration, the temperature, the constant light, and the water levels. The experimental group includes the petri dishes under the red, blue, and purple films, along with the petri dishes covered in aluminum foil. The control group is the petri dish that is constantly getting…

Therefore, muscle fibers were found to contract after the application of the three solutions. However, solution B (ATP + Salt), had a greater effect than the other two solutions based on the percentage of contraction which was 9.2%. Discussion: Petri Dish A The muscle fibers in the presence of ATP shortened by 0.07cm and 3.3% change, which means that the muscle contracted. According to Boundless, ATP is required for muscle contraction since it prepares the myosin for binding in the cross-bridge…

The conception of a child. Some view this immaculate manifestation of life as a gift in and of itself. One that should be left to nurture and grow, as it was originally intended. Others use this creation for a gift to others, to give to those who were not born with fully functioning organs within their body. While both parties see the conception of life as a gift, they strongly oppose each others views on how to use this. But where is the line drawn on the ethicality of stem cell research? I…

The common debate among for abortion to be permissible or impermissible always falls on the idea that abortion is murder, and thus the idea that life begins at conception. Many factors play a role in the abortion debate: one believing that life begins at conception, that all murders are impermissible, and whether a woman has a certain obligation to her body. The argument is flawed; for the simple plausible element that abortion is permissible. When you look at abortion, you need to decide which…
