Mitochondrion “Mitochondria are bean-shaped organelles that are known as the powerhouse of all living cells. Their function is initially centered around converting oxygen and other nutrients into adenosine triphosphate or more formally known as ATP”(MoleculeExpressions). ATP is the energy required by cells in order to perform its mandated metabolic activities. This process is also known as aerobic respiration and is the main reason as to why animals are mandated to breathe in oxygen. Without mitochondria

The west coast of the US consists of the highest levels of risk by a wide margin, particularly in the south-west (on the pacific tectonic plate fault line). Central Eastern regions bear areas of moderate risk

The Cure or the Disease? Genetically Speaking: The Cure or the Disease? World Hunger today or world hunger tomorrow is the question that faces us today. We have to understand the problem we are facing. As the human population approaches the 7 billion mark and still continues to grow at an exponential rate, agricultural experts asked whether the world can continue to produce enough food for everyone. . . . people in many developing countries such as China and India are becoming

I. What is endocrinology? * The study of hormones chemical messangers * Nucleus collectiom of cell bodies of neurons of CNS * Ganglia collection of cell bodies of PNS II. Neurotransmitters vs. hormones * Neurotransmitters: * released into synapses (aka synaptic cleft) via exocytosis * secreted from the secreting cell to the target * affinity of neurotransmitter receptor binding lower because more neurotransmitter concentrated in synapses * Hormones: * released

Systems theory: a scientific/philosophical approach and set of concepts, rather than a theory, for the transdisciplinary study of complex phenomena. It was first proposed by the biologist Ludwig von Bertalanffy in the 1940's (anthology: "General Systems Theory", 1968), as a reaction against scientific reductionism*. Rather than reducing a phenomenon (say, the human body) to a collection

What is Rational Unified Process? RUP is a Software Engineering Process. It is a disciplined approach to assigning tasks, roles and responsibilities within a development environment. RUP identifies the static and dynamic aspects of an SDLC. The static aspects are called the Workflows and the dynamic aspects are called Phases. The various Phases are Inception, Elaboration, Construction, and Transition. The 9 Workflows defined by RUP are Business Modeling, Requirements, Analysis and Design, Implementation

allows it to pass through some materials. The biological effects are potentially devastating based on the length of exposure and the length of the wavelength exposed to. The reason UV light can be so detrimental is due to its effect on DNA and the mutations that can occur because of exposure. The absorbance of UV photons causes the formation of pyrimidine dimers; these in turn create challenges to DNA replication. While DNA repair mechanisms can remove these dimers, with increased exposure and/or repeated

STEM CELLS Science has made many discoveries over the years and its discoveries have helped us understand why things happen and why they happen. We have had many great scientists who devoted their lives in laboratories testing many natural and chemical reactions. Medicine is a field in which over the years science has made a lot of improvements and many scientific tests helped us found the cure of many deadly deceases. Even though there has been a lot done there is still a lot more
