Lab 7: Moon Phases was designed to measure the relative position of the Sun and Moon over the course of one phase cycle (i.e. one month, 29.5 days) The idea for Lab 7: Moon Phases was to examine how the illumination of the moon by the Sun produces the different phase cycles we see as the Moon rotates around Earth and as the Earth rotates around the Sun. The observations of the Moon were taken on four different days in the month of February to March capturing four different Moon Phases.
In 2096, the Earth starts being exhausted of resources, water level rises due to climate change and the increasing radiation from the Sun. During this period, World War III happens with the two opposing sides are China and United States of America who are fighting for the ownership of the very limited resources on Earth. People would kill, steal, and rape others so that they can survive. Most people if not all have already lost their consciousness and sanity. However, a scientist named Sirloc is inventing a machine that hopefully will be able to solve the problem and bring peace back to Earth. The machine first receives the high energy electromagnetic wave from the Sun (in this case, its X-ray and UV) and has it colliding with a free electron. Then, the photon transfers some of its energy to the free electron. Therefore, the photo becomes less harmful and since the energy goes into increasing the electron’s kinetic energy which then generates electricity.
Lab 1 helps create a better understand of the changes in crystal structures when the annealing and quenching process is applied to 1020 and 1080 steel. The numbered steel refers to the ASTM grain-size number. Formula 1 is used to solve for the grain size.
This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment. We are then introduced to installation of a Wiki
A milk-based, litmus broth tube is incubated and observed after 48 hours. Observations include lactose fermentation without gas as well as with gas, the reduction of litmus, casein protein coagulation and casein and protein hydrolysis. These characteristics were all determined based on the color of the solution and the production of a curd, the curds density and the production of a gas. To determine the density of the curd, the tube was slightly turned to see rather or not it was mobile or concentrated towards the bottom.
Through the usage of gel electrophoresis the correct allele for each sample was able to be determined. Lanes one through three in the gel,were the positive control lanes they contained the PCR cocktail and a known high-quality template for the PCR reaction. First lane contained the sample with the +/+ allele, which had two copies of the ALU repeat allele. The first lane had a band at about 941 base pairs. The second lane in the gel contained the -/- allele and had its band at about 641bp, lower than the +/+ allele in lane 1. Since the +/+ has extra stretches of DNA, it should have a larger mass which makes it progress more slowly through the gel compared to the -/- allele which has less base pairs. The third lane contained the +/- sample, and after running the gel the lane had two different bands. This sample is heterozygous as it contained both alleles and thus had one band at about 941 base pairs and another band at about 641 base pairs. Lane four contained the negative control which only contained the cocktail mixture with water. There was no band present within this lane at it did not have any DNA present. The fifth lane contained student one’s PV92 DNA
The research study includes two measurements, the Progressive Aerobic Cardiovascular Endurance Run (PACER) test and the Situational Motivation Scale (SIMS). The first focus of the clinical experience assignment was to observe the guidance counselor administer the SIMS questionnaire to students. Two fifth grade classes were observed; students in both classes participated in a second steps teambuilding activity prior to completing the SIMS questionnaire. One of the objectives for this clinical experience was to observe how the guidance counselor administered the questionnaire. After the teambuilding activity, students in both classes received detailed instructions from the counselor on how to complete the questionnaire. It’s interesting to note

Biochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining. Approximately 60-90% of the Gram-positive bacterial cell wall is made up of peptidoglycan and interwoven teichoic acid, while only
