Forensic Entomology Essay

Forensic entomology is using insect biology to determine specific aspects of a crime. It can be used to determine time of death, whether or not a body has been moved, and also if the victim had been intoxicated with any substances. Insects are also prime examples of Locard’s principle when solving a crime. Insects can … Read more

The stem cell colonies

Meriam-Webster defines stem cells as: an unspecialized cell that gives rise to differentiated cells. This means the can turn into any cells the body is in need of . Their almost limitless potential has made stem cells a significant focus of medical research. Imagine having the ability to return memory to an Alzheimer’s patient, replace … Read more

Monosaccharides

Monosaccharides are polyhydroxy aldehydes or ketones; that is, they are molecules with more than one hydroxyl group (-OH), and a carbonyl group (C=O) either at the terminal carbon atom (aldose) or at the second carbon atom (ketose). The carbonyl group combines in aqueous solution with one hydroxyl group to form a cyclic compound (hemi-acetal or … Read more

The autonomic nervous system

The autonomic nervous system is made up of two divisions. There are many differences between these divisions. First of all there are anatomical and physiological differences. The parasympathetic division of the autonomic system origin is in the craniosacral outflow, the brain stem nuclei of cranial nerves III, VII, IX, and X; and spinal cord segments … Read more

What Is Biodiversity

Biodiversity is the measure of variety of the Earth’s animal, plant and microbial species; of genetic differences within species and of the ecosystems that support those species. The term first came to public attention in 1992 at the Rio Earth Summit at which a convention for the preservation for the maintenance of biodiversity was signed … Read more

Diphtheria (Corynebacterium diphtheriae)

Corynebacteria are Gram-positive, aerobic, nonmotile, rod-shaped bacteria related to the Actinomycetes. They do not form spores or branch as do the actinomycetes, but they have the characteristic of forming irregular shaped, club-shaped or V-shaped arrangements in normal growth. They undergo snapping movements just after cell division which brings them into characteristic arrangements resembling Chinese letters. … Read more

What’s Hot, What’s Not

Every fall, homeowners have the same problem: dead leaves. Trees shed leaves and taint once perfected lawns. To get rid of these leaves, people rake the leaves and assemble them into large piles that trucks come and remove. If these piles are left long enough, they will heat up. On a cold day, steam can … Read more

The progress of Biotechnology

The scientific rules of genetics were not known until the nineteenth century, when Gregor Mendel determined from his study of plants that particles that can not be seen carry traits that are passed on from generation to generation. In 1953, James Watson and Francis Crick made the makeup of the genetic code called deoxyribonucleic acid, … Read more

Darwins Theory of Natural Selection

Charles Darwin revolutionized biology when he introduced The Origin of Species by Means of Natural Selection in 1859. Although Wallace had also came upon this revelation shortly before Origins was published, Darwin had long been in development of this theory. Wallace amicably relinquished the idea to Darwin, allowing him to become the first pioneer of … Read more

Science is moving at such a rapid speed these days, between cloning, gene therapy, miracle drugs, exotic therapies, etc. One of the most significant breakthroughs came in November 1998, when two separate researchers successfully isolated stem cells from human embryos and aborted fetuses. Stem cells are primordial cells of a human organism, which are capable … Read more

Peter Mitchell (1920 – 1992): Chemiosmotic Hypothesis

Peter Mitchell’s 1961 paper introducing the chemiosmotic hypothesis started a revolution which has echoed beyond bioenergetics to all biology, and shaped our understanding of the fundamental mechanisms of biological energy conservation, ion and metabolite transport, bacterial motility, organelle structure and biosynthesis, membrane structure and function, homeostasis, the evolution of the eukaryote cell, and indeed every … Read more

Homeostasis Report Essay

Homeostasis is the state of equilibrium in which the internal environment of the human body remains relatively constant. Two excellent examples of homeostasis are how the body maintains a constant temperature and blood pressure during strenuous physical activity or exercise. Although there are many other activities in the body that display homeostasis, I will only … Read more

Involvement of K+ in Leaf Movements During Suntracking

Many plants orient their leaves in response to directional light signals. Heliotropic movements, or movements that are affected by the sun, are common among plants belonging to the families Malvaceae, Fabaceae, Nyctaginaceae, and Oxalidaceae. The leaves of many plants, including Crotalaria pallida, exhibit diaheliotropic movement. C. pallida is a woody shrub native to South Africa. … Read more

Transitions of Reptiles to Mammals

The Fundamental Structural Unit Of All Living Organisms

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0. 1 micrometer in diameter, to the … Read more

Diverrsity of Plants

Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the … Read more

The Spider Division of Frankenstein, Inc

With the ever-increasing problem of pest control, it is clear that some form biological must be implemented in order to help farmers. This biological control must be able to effectively control the pest population, this means not killing them but rather never letting the pest populations get too large. Through computer-simulated programs the Spider Division … Read more

The Plant and Photosynthesis

In order to carry on photosynthesis, green plants need a supply of carbon dioxide and a means of disposing of oxygen. In order to carry on cellular respiration, plant cells need oxygen and a means of disposing of carbon dioxide (just as animal cells do). Unlike animals, plants have no specialized organs for gas exchange. … Read more

Biological Species Concept (BSC)

What are biological species? At first glance, this seems like an easy question to answer. Homo sapiens is a species, and so is Canis familaris (dog). Many species can be easily distinguished. When we turn to the technical literature on species, the nature of species becomes much less clear. Biologists offer a dozen definitions of … Read more

Aqutic Life

Plants are critical to other life on this planet because they form the basis of all food webs. Most plants are autotrophic, creating their own food using water, carbon dioxide, and light through a process called photosynthesis. Some of the earliest fossils found have been aged at 3. 8 billion years. These fossil deposits show … Read more

Human cloning

The biological definition of a clone is an organism that has the same genetic information as another organism or organisms (“Cloning”, 1997). Is cloning the gateway to the future or the door to disaster? From this definition and from information about the science behind cloning on cloning, it seems ethical. This statement ignores information about … Read more
