D’Juan McPherson May 5‚ 2011 BIO 100 CheckPoint: Mitosis and Meiosis Mitosis and meiosis are both important to a living organism because they represent cell divisions that are very important to every living organism because without cell division all living organisms would fail to reproduce‚ eventually dying out. Cell division plays a very important role in the life cycle of a cell. Mitosis and meiosis are important to living organism because they help living organisms to grow‚ develop‚ and

Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent‚ 2 chromosomes or 4 chromatids (TETRAD)‚ this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA‚ and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes

Bonnie Bell Mrs. Legary Biology P.6 21‚ Sept. 2011 Milk Lab Final This investigation consists of testing the reaction between milk‚ food coloring‚ and dishwashing soap. Different kinds of milk were tested‚ depending on the amount of milk fat content. The investigation was based on 2 questions. Lab one’s problem statement‚ using only milk fat and food coloring was: How does food coloring react in different kinds of milk fat? The second lab’s problem statement‚ using milk fat‚ food

Lab #5 Questions and Answers 1. Which tool is better at performing protocol captures and which tool is better at performing protocol analysis? Wireshark is better for performing protocol analysis and Netwitness Investigator is best at performing protocol captures. Wireshark does well at both aspects‚ which makes it a little better. 2. What is promiscuous mode and how does this allow tcpdump‚ Wireshark‚ and NetWitness Investigator to perform protocol capture off a live network? Promiscuous

Lab 5 Assessment Questions 1. What are the three major categories used to provide authentication of an individual? a. Password b. Token c. Shared Secret 2. What is Authorization and how is this concept aligned with Identification and Authentication? Authorization is a set of rights defined for a subject and an object; this concept is aligned with Identification and Authentication because these are the 3 steps to the access control process 3. Provide at least 3 examples of Network Architecture

Abstract The objective of this lab was to determine the convective heat transfer coefficient of a heated sphere in an quiescent environment. In the experiment a hot brass sphere was put into water and cooled. The temperature of the sphere was recorded over a time of 600 seconds to see how it cooled and given temperature was recorded every 20 seconds. Results were then calculated at both of the time values 300 and 600 seconds. For the experimental results at time 300 seconds‚ the Rayleigh number
