Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

Exercise 1.1.9 Exercise 1.1.10 Exercise 1.1.11 Exercise 1.1.12 Lab 1.1 Review: 1. 127 to binary 2. Equivalent because the 0’s are just placeholders. 10 = 0010 3. First 4 digits of a Base 5 numbering system would be (left to right) 625 125 25 5 4. The leading Zeros would make it difficult to build a decimal to binary conversion table in excel. Excel doesn’t see numbers with leading 0s as real numbers. Exercise 1.2.1 110 and 1001 = 1111 Exercise 1.2.2 110 and 101 = 1011 Exercise 1.2.3

Microbiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling

1. During the install‚ the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective‚ why is it important for a system to keep accurate time? UNIX systems base their notion of time on interrupts generated by the hardware clock. Delays in processing these interrupts because UNIX systems clocks to lose time slowly but erratically. These small changes in timekeeping are what the time scientist call jitter. The Time protocol provided a server’s notion of time in

Exercise 1 - Leadership Questionnaire Directions: The following items describe aspects of leadership behavior. Respond to each item according to the way you would most likely act if you were the leader of a work group. Circle whether you would most likely behave in the described way: A – always; F – frequently; O – occasionally; S – seldom; or N – never. AFOSN 1. I would most likely act as the spokesperson of the group. AFOSN 2. I would encourage extra work (no more than average). AFOSN 3. I

Graph 1‚ illustrates the pH of each quadrat. The pH in Quadrat 1 was more acidic than the pH in Quadrat 2‚ 3‚ and 4 this is due to the slope of the ground (refer to Graph 8)‚ different soil substrate and the decomposition of organic matter. As can be seen from Graph 8‚ the soil pH increased with a decrease in the slope of the ground. In Quadrat 1‚ the soil had a pH of 7.5 due to having a higher soil elevation of -8° in comparison to Quadrat 2‚ 3 and 4‚ in which the slope of the ground was -2°‚ -2°

HISTOLOGY PURPOSE: The purpose of this exercise is to be able to identify and correctly name the major tissue types in the body‚ as well as identifying the subcatergories of tissue types while observing them through the microscope and diagrams‚ and be able to explain the location and function of the tissue types in the body. There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used. EXERCISE 1: EPITHEILIAL TISSUE Epithelial Tissue Observations

ANATOMY 2 LAB 1 – RECEPTORS Questions: 1. How is the distance between receptors related to sensitivity of a stimulus? * The greater the distance between receptors and stimulus the lesser sensitive are the stimulus. The smaller area‚ the more sensitive. 2. What does the two-point discrimination test measure? * It measures the smallest distance at which two points of contact can be felt or measures areas that are more sensitive and has more motor interactions. 3. What areas of

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and
