    Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life

    Lab Report 1                              Principles of Biology 1(BIOL 100) Fall 2001                              Gerard Chretien Living cells perform a multitude of chemical reactions very rapidly because of the participation of enzymes. Enzymes are biological catalysts, compounds that speed up a chemical reaction without being used up or altered in the reaction. The material with which the catalysts reacts, called the substrate, is modified during the reaction to form a new product. But because

    Biology 1. The virus is made up of five parts and is in the size range of 10 nm-300 nm in diameter. The first is the coat made up of protein that protects the virus to a point. Next is the head that contains the genetic material for the virus. The genetic material for a virus is DNA. The two other parts are the tail sheath and the tail fibers that are used for odd jobs. I believe that a virus is not considered to be a living creature due to the fact it is a parasitic reproducer. To me it is just

    Within the broader context of crime scene investigation, forensic biologists play the role of collecting and analyzing biological evidence in order to decipher exactly what happened at the scene of the crime, and who was involved (Forensic Biologist, n.d.; Forensic Science, n.d.). Much of the evidence collected by forensic biologists consists of both ecological and biological matter, including but not limited to: dirt, blood, teeth, insects, fingerprints, and saliva (A Simplified Guide to Forensic

    things also play a large part in the survival of organisms including sunlight, atmospheric gases, water and minerals. 3. Describe how biology affects five areas of life: food, clothing, shelter, health, and fuel. Food: We can not survive more than 3 months without food. And all foods come from living things, or indirectly from the products of organisms. Biology studies farming, pest control, livestock management, nutrition, food processing, and food preservation to improve the quality and quantity

This book is biology revisited. It will provide:a. Deeper understanding.b. A more organized level of understanding.B. To biologists, life reflects its ancient molecular origins and its degree of organization. Life is:1. A way of capturing and using energy and materials.2. A way of sensing and responding to specific changes in the

    Synoptic Biology Synoptic biology is the ability to select and apply general principles to unfamiliar situations/data. Modules 5 and 8 will have questions that test your understanding of modules 1,2,3 and 4. This is called the synoptic assessment. The synoptic element of modules 5 and 8 is worth more marks that the actual module content. This means you have to get to grips with the synoptic element in order to do well. This booklet is designed to help you to do so. How much of module

    MARINE BIOLOGY CASE STUDY LAB - PART 2 Analysis 1. By running the programming with a fish.dat file containing the information for a 2 x 2 tank size, and changing the starting positions for fish A, B, and C, according to the problem, I was able to evaluate the random sequence of steps taken by each fish. The fish move in sequence of A, B, and then C. Then they move according to open slots. If a fish is covered on both sides by another fish, it is unable to move and, therefore, stays in that exact

    definition, a population is a group of organisms of the same species living and interacting in a particular area (Pg. 451 Biology for a Changing World). On the other hand, an ecosystem is defined as the living and nonliving components of an environment, including the communities of organisms present and the physical and chemical environment with which they interact (Pg. 451 Biology for a Changing World). In all ecosystems, there tends to be a population cycle, meaning that there are repeating rises

    Southern blot Various molecular biology methods are used to investigate the information of genomic entities from different origins. One of the core technique in the field is Southern blot, which is used to detect DNA molecules of interest among many other DNA sequences and to retrieve information about their identity, size, organization and abundance within a genome. The technique was named after its inventor Professor Edwin M. Southern, a renowned British molecular biologist who developed the procedure
