...What is life? Shauna L Joseph BIO/101 December 22nd, 2014 Heather Browning What is life? Part I: Media Relevancy Read each statement. Write a 100-word summary explaining how the chosen media piece supports the statement. Include reference citations. 1. Find a media piece—article, video, presentation, song, or other that recognizes the fundamental concepts of chemistry in biology. Include a link or reference citation for the piece and describe how it helped you better understand how fundamental concepts of chemistry affect biology. After my research at www.infoplease.com it has helped me to understand how fundamental concepts of chemistry affects biology by breaking down the concept of why chemistry and biology goes hand in hand. Infoplease, (2000-2014), stated that biology explained the living parts of the world and their environment. It also said that biology requires a little knowledge of chemistry and that it is important to know aspects of chemistry to make biology come alive. We all know that the understanding of chemistry requires a little mathematic but it is not important to go into detailed mathematical applications to understand the principles of biology. So what is the fundamental concepts of chemistry in biology? Biology overlaps with chemistry in explaining the structure and function of all cellular processes at the molecular level.

It located in the thylakoid membrane of the chloroplast. It is the light-independent reactions take place. The thylakoid membrane absorbs photon energy of different wavelengths of light. Embedded in the thylakoid membranes are photosystems: Clusters of 200 to 300 pigments and other molecules that surround a pair of chlorophyll a molecules. In plants, there are two photosystems, Photosystem I and Photosystem II. The light-dependent reactions begin in photosystem II. When a chlorophyll a molecule within the reaction center of PSII absorbs a photon, an electron in this molecule attains a higher energy level. The begins with Photosystem II, where trapped light energy is used to split water, a process known as photolysis: H2O → 2H+ + 2e−+ O. It located in the thylakoid membrane. The electron is transferred from one to another molecule and creates a chain of redox reactions. It is an electron transport chain (ETC). Along the way, the energy released by the electrons is used to make ATP in a process called photophosphorylation. The molecular details of this ATP-generating system are similar to those used by the mitochondrion in oxidative phosphorylation. Phosphorylation refers to the addition of a phosphate group ADP to form ATP. The reaction sequence is: ADP + Pi → ATP. The electron flow goes...

...Bio 109: Nutrition Spring 2015 Questions from the First Readings 1) How are we first infected with our microbiome? Give at least three examples or situations of how our microbiome might be influenced throughout our life time. We are first infected with microbiomes during birth. If a mother gives birth natural, when the baby passes through the vagina, it will be exposed to various microbiomes . After birth, our biomes continue to be shifted based on our environment and what we are exposed too. As a toddler, our parents heavily influence our biomes. An example of this can be breastfeeding or direct contact with other family members. Another case that can influence our microbiomes is the food we consume. An individual who eats at restaurants often can be exposed to more microbiomes than an individual who cooks their own meal. Traveling is also one of the major influencer of microbiomes. When a person travels, they are more likely to be exposed to new bacteria or viruses than they have been used too. 2) H. pylori has co-existed with humans for many thousands of years. Why has H. pylori persisted in the human population. What are the known benefits of having this bacteria living with us? What are the known problems?...

...Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size of the island will influence the population. • The amount of precipitation will influence beak size. • Variances in beak size will influence beak size. MATERIALS The materials needed for this experiment consist of a computer and access to the Evolution Lab on the University of Phoenix student website. In the Evolution Lab there are two islands, Darwin Island and Wallace Island. There are seven variables that can be changed to run many different experiments on both islands. The variables are beak size, variance of beak size, heritability, clutch size, island size, population, and precipitation. METHODS In all of the experiments Darwin Island was used as the control group and Wallace Island was the experimental group. So, in each test, the variables for Wallace Island were altered and the variables for Darwin Island were left alone. The first experiment was to determine whether or not the size of the island affected the population. To do this, the only variable that...

...IT320 Unit 5 HW 1. When a router is first powered on, it completes a four-step initialization process: 1. Preforming a power-on self test (POST) 2. Loading a bootstrap program 3. Loading an IOS 4. Loading a configuration file The last three of these steps require the router to copy the files into RAM. Normally, most routers load an IOS image that is stored in flash memory and an initial configuration stored in NVRAM. 2. Routers use the following logic, in order, to attempt to load an IOS: 1. Load a limited-function IOS if the configuration register’s last hex digit is set to 0 or 1. 2. Load an IOS based on the configuration of boot system commands in the startup-configuration file. 3. Load the first file in flash as the IOS. 4. Use TFTP broadcasts to find a TFTP server and download an IOS from that server. 5. Load a limited-function IOS from ROM. In Step 1, the configuration register is a16-bit number that Cisco routers store in a hidden area of NVRAM. It can be set in a couple of ways and can be seen using the show version command. The most commonly used way to set its value is to use the config-register global configuration command. Routers use the 4 low-order bits of the configuration register as the boot field, which tells the router what to do in the first of the preceding five decision steps. If the value of the field is set to 0, the router loads the ROMMON (ROM Monitor), which is used for password recovery. If the value is set to1, the router loads...

...BitLocker Drive Encryption Overview 73 out of 98 rated this helpful - Rate this topic Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Vista BitLocker Drive Encryption is a data protection feature available Windows Server 2008 R2 and in some editions of Windows 7. Having BitLocker integrated with the operating system addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers. Data on a lost or stolen computer is vulnerable to unauthorized access, either by running a software-attack tool against it or by transferring the computer's hard disk to a different computer. BitLocker helps mitigate unauthorized data access by enhancing file and system protections. BitLocker also helps render data inaccessible when BitLocker-protected computers are decommissioned or recycled. BitLocker provides the most protection when used with a Trusted Platform Module (TPM) version 1.2. The TPM is a hardware component installed in many newer computers by the computer manufacturers. It works with BitLocker to help protect user data and to ensure that a computer has not been tampered with while the system was offline. On computers that do not have a TPM version 1.2, you can still use BitLocker to encrypt the Windows operating system drive. However, this implementation will require the user to insert a USB startup key to start the computer or resume from hibernation, and it does not provide the pre-startup system integrity verification...
