Biology - 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 and its characteristics....   [tags: Biology]

Evolutionary Developmental Biology - ... Evo-devo has focused on the evolution of the genetic mechanism of development. Rapid improvement in the cloning of regulatory genes and new techniques of visualising gene expression in embryonic tissues has made this the most valuable part of experiential evo-devo at present.. The discovery of extensive similarities in gene regulation between distantly related species with essentially different body structures was an initial accomplishment. Evo-devo concentrates on the evolution of genetic tools that underlie the development of organisms, for example, the evolution of the genes during mutation, duplication and divergence (Müller, 2007)....   [tags: Biology ] 2219 words

Practical Applications of Evolutionary Biology - Charles Darwin and Alfred Wallace's concept of natural selection and descent with modification helped shape the theory of evolution which holds as much weight as the theory of relativity per se. Evolutionary biology is the science devoted to understanding how populations change through time in response to modifications of their environment and how new species come into being by studying adaptation and diversity (Freeman and Herron 2004). Evolutionary biology has proved that all organisms have evolved from a common ancestor over the last 3.5 billion years....   [tags: Biology] 1498 words

Biology - 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.

Society is full of messages telling us what is beautiful, but what are those definitions based on. Do we consciously decide whom we are attracted to, or is biology somehow involved. The issue of beauty and how we define it has been studied for centuries. Scholars from all fields of study have searched for the "formula" for beauty.

Biology Notes - 1. The ability of ice to float because of the expansion of water as it solidifies is an important factor in the fitness of the environment. If ice sank, then eventually all ponds, lakes, and even oceans would freeze solid, making life as we know it impossible on earth. During the summer, only the upper few inches of the ocean would thaw. Instead, when a deep body of water cools, the floating ice insulates the liquid water below, preventing it from freezing and allowing life to exist under the frozen surface....   [tags: Biology Study Tests] 3489 words

biology - A gastric gland is a tubular structure in the vertebrate stomach that secretes gastric juices. The gastric glands have three types of cells that secrete different components of the gastric juice. One of them is being a chief cell, which is a rust color and is an inactive form of the digestive enzyme Pepsin. Pepsin begins the digestion of proteins in food. Pepsin is a Peptidases, which is an enzyme that breaks peptide bonds of proteins. Pepsin is found in the mucosal lining of the stomach that breaks down the protein in the food we eat....   [tags: essays research papers] 362 words

Each amino acid has a specific tRNA activating enzyme that helps tRNA to combine with its complementary mRNA codon. The enzyme has a 3 part active site that recognizes three things: · A specific amino acid · ATP, · A specific tRNA. The enzyme attaches the amino acid to the 3' end of the tRNA.

biology - LIPIDS AND NUTRITION Lipids can be defined as molecules, synthesized by biological systems, which have , as a major part of their structure, long aliphatic hydrocarbon chains that may be branched or unbranched, may form carbocyclic rings and may contain unsaturated linkages. Lipids have been matter of health concern in human beings. There are several reasons for it: v High prevalence of cardiovascular disease (CVD) and most of the lipid chemists have associated this with high consumption of fat especially saturated fatty acid (SFA) v Obesity v Thus the widespread desire to reduce fat in the diet has given rise to low and reduced fat products....   [tags: essays research papers] 709 words

Using Scientific Inquiry Model in High School Biology - ... Students need to also be able to recall specific information in biology in order to meet the objectives set forth on state-mandated tests. These tests are a major aspect in classrooms, due to the fact that teachers and students are now held accountable for passing rates. So I pose this question, “Is there an exact way to teach students every required objective on the state-mandated tests and help them learn and retain the information without being faulted for “teaching to the test?” According to Longo (2010), educators are blamed for hindering students by “teaching to the test”, but by incorporating inquiry-based learning in the classroom, student’s creativity, motivation, wonderment, and curiosity will expand....   [tags: Education]

Biology Summary - We have known for centuries that traits are passed from parents to offspring. What has not always been understood is how traits are determined. One explanation that appealed to scientist for many centuries was that traits of parents were blended, or mixed in offspring. The blending hypothesis accounted for many observable traits and was widely accepted for many years. However, the idea of blending could not account for the appearance of unexpected traits in some offspring. It was not until scientist discovered the cellular basis of life that the inheritance of traits was better understood....   [tags: essays research papers] 1350 words

Breeding Habits of Water Birds - Chapter 1. INTRODUCTION Many species aggregate for feeding, roosting and nesting activities, which are prevalent among water birds (Weins, 1992). Why animals form breeding colonies is a major unresolved question in evolutionary biology. The topic continues to stir lively debate (Danchin & Wagner 1997, Tella et al., 1998) and has been the focus of long term studies (Hoogland 1995; Brown & Brown 1996; Danchin et al. 1998). One of the principal issues has been whether colonies form due to limited breeding habitat; with animals forced into nesting aggregations at a nest cost, or result from social benefits of clustering (Food finding, reduced predation; Lack 1968; Alexander 1974; Hoogland & Sherman 1976; Wittenberger 1981)....   [tags: Biology ] 976 words

Oxidative damage to DNA, proteins, and lipids accumulates with age and contributes to degenerative diseases and the aging phenomenon by disrupting cellular homeostasis (1, 3, 4, 27). At the cellular level, oxidative stress generated by reactive oxygen species (ROS) and ROS-modified molecules can influence a wide range of cellular functions, leading to uncontrolled cell proliferation or accelerated cell death (20)....   [tags: Biology] 613 words
