Nt1310 Unit 4 Test Lab Report

Our lab results on all three data table experiments had a percent error less than 5 percent. When examining these results I can be almost certain it was not systematic error due to the fact that a major percent error was not detected on every trial that was run in each of the three tables. With there being some percent error there is the possibility for random error which are from unknown factors, which could come from impact of outside forces like the air track interfering with the acceleration of the cart. Beings that this was the first lab for my lab partners and I were working there was room for slight personal errors with our use of the computer program as well as the lab equipment.

Activity 1 Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because it caused to decrease in the concentration gradient. Increasing extracellular K+ causes the membrane potential to change to a less negative value because extracellular K+ is increasing, which it will cause intracellular K+ to be less. A change in extracellular Na+ did not alter the membrane potential in the resting neuron because there are a lot of K+ leak channels than Na+ leak channels The relative permeability of the membrane to Na+ and K+ in a resting neuron is that Na+ leak channel is less, but K+ leak channels has more so the membrane become less permeable to Na+.

LABORATORY REPORT EXERCISE #5 INTRODUCTION TO THE COMPOUND LIGHT MICROSCOPE, PLANT AND ANIMAL CELLS Name_______________________________Section_____Teacher______________Date________ PRE-LAB QUESTIONS - answer the following questions using your textbook and valid internet sources. Be sure to cite your sources at the end of the prelab. You can type your answers to all questions except #1 and #9 directly into this document and then submit via Canvas. Type the answers for #1 and #9 at the end of the document. 1.

1. Identify the range of senses involved in communication • Sight (visual communication), Touch (tactile communication), Taste, Hearing (auditory communication), Smell (olfactory communication) 2. Identify the limited range of wavelengths and named parts of the electromagnetic spectrum detected by humans and compare this range with those of THREE other named vertebrates and TWO named invertebrates.

1. There are two ways of maximizing points in this experiment. The first one is that I should connect myself to a vertex that is in the biggest component and purchases immunization. Since the probability of being infected is based off of expected value, I would have less than 1% chance of getting infected. The second way is that I try to make myself stay in the second-largest connected component.

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.

1. Describe the study design (is it correlational, experimental, survey research, etc.). The study is Level 3, experimental. The participants are within subject design experiences because since the subjects were divided into two groups by gender.

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.

4.) I noticed that there is a relationship between the ionic radius and the atomic number of the representative elements in Group 1A. The higher the atomic number, the bigger the ionic radius is. So, while hydrogen has an atomic number of 1 and Francium has an atomic number of 87, it is safe to assume that FR has a higher ionic radius. This is true; the ionic radius for Hydrogen is 0.012, and for Francium, it is 0.194.

Goals of the Lab 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.

Perhaps many are confused about the existing commands linux, this time I will discuss about the linux basic commands used along with examples of its use.

pecial Conditions Permit Number 9576 1. This permit covers only those sources of emissions listed in the attached table entitled “Emission Sources - Maximum Allowable Emission Rates” (MAERT), and those sources are limited to the emission limits and other conditions specified in that table. Startup, Shutdown, and Maintenance Emissions 2. This permit authorizes emissions from Flare (Emission Point No. [EPN] 400) for startup and shutdown activities associated with product transitions.

We will Contrast and compare the failures of the Therac-25 and the Ariane 5. What key similarities and differences identified? Which specific software problems caused the failures? What was put in place to prevent such failures from occurring again? What lessons do you think should Software Engineers take away from these two failures?
