...Title: Seed Plants 2: Angiosperms Aim: To draw and label six diagrams related to flowering plants Introduction: Angiosperms are flowering, fruit-bearing plants or trees known for having ovules (and therefore seeds) developed within a closed ovary. Angiosperms are plants producing flowers. Thus, they are also commonly called as the flowering plants. They belong to the kingdom Plantae, subkingdom Embryophyta. They can be classified as monocotyledons and eudicotyledons. Characteristics of Angiosperms * The flowers serve as the reproductive organs for the plant.(exchanging genetic information) * They have small pollen grains that spread genetic information from flower to flower. * They have stamens- reproductive structures found in flowers that produce the pollen grains that carry the genetic information. * They have much smaller female reproductive parts, allowing them to produce seeds more quickly. * They have carpel that encloses developing seeds that may turn into fruit. * A great disadvantage is the production of endosperm. It is a material that forms after fertilisation and serves as a highly nutritional food source to the developing seed and seedling. The life cycle of Angiosperms They follow: * Seed * Germination * Sprout or seedling * Mature plant * Flowering Materials: * Flower for dissection (hibiscus flower) * Scalpel * Dissecting microscope * Prepared slide of young lily anther, c.s. * Prepared...

...Wireless Spectrum Introduction This lab is going to be very interesting and challenging. We are being introduced to what, for some, is going to be the first time ever using a program that captures and records signals. We must then analyze them and use this as a tool to better be prepared to install and even troubleshoot our networks. My goal for this lab would be to gain a better understanding of this program and be able to recognize how it could be useful for me in my future endeavors. 1. Are any channels being used that overlap other channels? (10 points) It would appear that channels 1, 8 and 11 have the most use going on and that 8 and 11 overlap each other. 2. If you had to install a new wireless LAN, what channel would you use? (10 points) I would use something in the 3-6 range as it would provide the least amount of overlap with other channels. 3. What channels are being used? (10 points) It appears to me that channels 1, 5, and 11 are currently in use. 4. What channel is being used the most? (10 points) Channel 11 appears to have the most use going on on currently. 5. What type of signal is being shown? (10 points) The signal appears to match that of a HyperX RFID Reader. 6. What frequency, not channel, is being used? (5 points) The frequency in use is 2450 mhz. 7. What type of signal is being shown? (10 points) The signal being displayed is 802.11g. 8. How strong in dBms is this signal? (5 points) The signal strength appears...

...56 Define the following terms: Cellular respiration (aerobic respiration) (2 points) Cellular respiration is the process by which cells get their energy in the form of ATP. There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be used in the presence of oxygen. Aerobic respiration, or cell respiration using oxygen, uses the end product of glycolysis in the TCA cycle to produce more energy currency in the form of ATP than can be obtained from an anaerobic pathway. Fermentation (anaerobic respiration) (2 points) Fermentation is a metabolic process converting sugar to acids, gases or alcohol. It occurs in yeast and bacteria, but also in oxygen-starved human muscle cells. Fermentation is used by humans to make beer and food, like kimchi. Fermentation is a form of anaerobic digestion that generates ATP by the process of substrate-level phosphorylation. Summarize what occurs during the three steps of cellular respiration and indicate where each process takes place in the cell. (6 points) Glycolysis: It is a process that occurs in the cytoplasm. It converts each molecule of glucose to two molecules of pyruvic acid. It refers to an anaerobic process that proceeds whether or not oxygen is present or not. The pyruvic acid diffuses into the inner compartment of the mitochondrion where a transition reaction occurs that starts to prepare pyruvic acid for the next stage of respiration. Krebs cycle-This is...

...Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems, and countless other objects. This activity is based on Lab 4 of the eScience Lab kit. Although you should read all of the content in Lab 4, we will be performing a targeted subset of the eScience experiments. Our lab consists of two main components. These components are described in detail in the eScience manual. Here is a quick overview: * In the first part of the lab, you will measure the force it takes to pull objects of different mass. This experiment focuses on the effects of frictional forces. (eScience Experiment 1) * In the second part of the lab, you will investigate the effects of air resistance by performing controlled drops of coffee filters. Notes: * Please follow the instructions in this document for the air resistance experiment. * Record all of your data in the tables that are provided in this document. Take detailed notes as you perform the experiment and fill out the sections below. This document serves as your lab report. Please...

...LAB 5 IT220 Exercise 5.1.1 * The 802.1 standard defines the 802 family of standards, describes the local area network, and defines the LAN address format. Exercise 5.1.2 * The 802.3af standard originally defined PoE functionality. The standard was enhanced in the year 2009, the name of it is 802.3at. Exercise 5.1.3 * 500 meters * 185 meters * 100 meters * Fiber Optic * UTP, 100 Meters * UTP, 100 Meters * Multi-Mode-Fiber Optic, 550 Meters * Single Mode- Fiber Optic * UTP 4 Pairs, 100 Meters Exercise 5.1.4 * The numeric prefix before BASE means the speed in Mbps. The inclusion of a postfix of -T means that the cable is a twisted pair standard. Lab 5.1 Review 1. The maximum speed of traffic would be between 10Mbps, and 100Mbps because they would have to negotiate the amount of bandwidth to send the node in between the two different network standards. 2. It is possible by also using a negotiation to uphold the maximum speed of the lesser UTP wire for example if Cat3 and Cat5e had to negotiate the Cat5e would have to meet Cat3’s standard maximum speed. Exercise 5.2.1 * A MAC address must be unique for every NIC card produced because they are being compared to all other unicast MAC addresses in the same LAN. The effect would be that the MAC address would be duplicated. Exercise 5.2.2 * It gives information on the connection its physical address and DHCP status. Exercise 5.2.3 * The physical...

...Lab 5 The biggest difference between these two types of networks is one uses network cables and one uses radio frequencies. A wired network allows for a faster and more secure connection and can only be used for distances shorter than 2,000 feet. Several other disadvantage of a wired network such as the “need to run cables in difficult environments through walls, floors and ceilings. Cables need to be run from computer to computer and switch to switch. Process can be time consuming. Loose cables likely remain the single most common and annoying source of failure in a wired network.” (PACE University, n.d.) While a wireless network is a very useful and convenient networking device, however these types of networks a lot less secure and transmission speeds can suffer from outside interference. Although wireless networking is a lot more mobile than wired networking the range of the network is usually 150-300 indoors and up to 1000 feet outdoors depending on the terrain. The cost for wired networking has become rather inexpensive. Ethernet cables, hubs and switches are very inexpensive. Broadband routers cost more, but these are optional components of a wired network, and their higher cost is offset by the benefit of easier installation and built-in security features. The primary parts of a wired network are the cables, network adapters, and routers. Wired LANs offer superior performance. The tools needed would be a Crimping tool, Punch Down tool, Cable cutters, Cable strippers...

...Lab Five Executive Summary A security test is a method of evaluating the security of a computer system or network by methodically validating and verifying the effectiveness of application security controls. A web application security test focuses only on evaluating the security of a web application. The process involves an active analysis of the application for any weaknesses, technical flaws, or vulnerabilities. Any security issues that are found will be presented to the system owner, together with an assessment of the impact, a proposal for mitigation or a technical solution (Open Web Application Security Project [OWASP], 2014a). Vulnerability is a flaw or weakness in a system's design, implementation, operation or management that could be exploited to compromise the system's security objectives. A threat is anything such as a malicious external attacker, an internal user, or a system instability that can harm the owner’s assets by an application or resource of value, such as data in a database or in the file system by exploiting vulnerabilities. A test is an action to demonstrate that an application meets the security requirements of its stakeholders (OWASP, 2014a). Test to Be Performed The first phase in security assessment is focused on collecting as much information as possible about a target application. Information Gathering is the most critical step of an application security test. The security test should endeavor to test as much of the code base as possible...

...This assignment was designed put us, the student in a situation where we are placed in the supervisor position. In this assignment put the supervisor in a position of having to pick and choose what tasks to do themselves and what tasks should be delegated out after coming in and finding their basket full of tasks that need to be dealt with. When you obtain the position of supervisor, there is usually far too much for just you to do, therefore it is important to learn what to delegate and who to delegate it to. The most important tasks should be done by the supervisor but as far as things such as someone’s vacation hours and stocking merchandise for the store, those tasks should be delegated out to the assistant manager and to the store clerks. Being a supervisor means being in a role of leadership, logic, common sense, and decision making for yourself, the employees, and for the company. The “in Basket” debate and discussion gives us and our fellow classmates the opportunity to see if we can successfully delegate out certain tasks as a supervisor at a fictitious company. The discussion between me and fellow classmates was a great one and it appeared as though everyone agreed on everything accept for different incidents. The only two incidents where I came across disagreement were in regards to task number 3, and task number 4. These are the examples in which I will be using in this paper as far as disagreeing is concerned. Task number 3 is in regards to the mall hours changing...
