Fetal alcohol syndrome
Fetal alcohol syndrome Fetal alcohol syndrome The 1990s is witnessing the significant impact alcohol-related birth defects are having on our society. These birth defects are caused by maternal use of alcohol during pregnancy which are irreversible, yet preventable. The most severe outcome, fetal alcohol syndrome (FAS), to the less easily diagnosed fetal alcohol effects (FAE). The incidence of FAS is estimated at .33 per 1,000 live births. The estimated incidence of FAE is three times ...
Fetal development
Fetal development Fertilization Fetal development starts with the process of fertilization. It starts when the female ovulates producing an egg. This egg then travels into the fallopian tube where it waits to be fertilized. Once sperm enter the body they must travel up the uterus until they make their way up to the egg. Once at the egg the sperm try to get in. They sperm wiggle their tails until they make it in. Once it makes it in the egg will not any other sperm in. ...
Fiberoptics
Fiberoptics Description Fiber Optics "A friend of mine once said that the trouble with being an architect is that everyone is an architect; everyone knows what's good and what's bad. I seem to remember the same story told by an economist. In physics we don't have that problem" (Sobel ix). Fiber optic technology has been inevitable since the first mention or speculation of light by Pythagoras in the 6th century B.C. (Sobel 1) Because of its flexibility and compara...
Finding mass using the inertial balance
Finding mass using the inertial balance Finding Mass Using the Inertial Balance Theory: Physics can be referred to as the study of various properties of matter and energy. Matter can best be described by looking at the mass of an object. Mass is the amount of material that is in an object. Mass can be found by using a spring scale, a balance scale, or an inertial balance. Inertia is the resistance by mass to any change in its state of motion. Scientific Law states that mass and i...
Fermentatiom by yeast
Fermentatiom by yeast Fermentation of glycine, water, sucrose, galactose, and glucose as induced by yeast. ABSTRACT This lab attempted to find the rate at which Carbon dioxide is produced when five different test solutions: glycine, sucrose, galactose, water, and glucose were separately mixed with a yeast solution to produce fermentation, a process cells undergo. Fermentation is a major way by which a living cell can obtain energy. By measuring the carbon dioxide released by the t...
Fertilizers
Fertilizers Fertilizers are substances added to the soil sprayed on leaves of plants to help them grow better or in some cases faster. Plants need twenty essentail elements to help them grow. Plants make carbohydrates. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium the most to grow healthy. Most soils naturally contain enough trace elements for field crops, but such elements must be added when certain fruits and vegetable plants are grown. Nitrogen, phosph...
Fetal alcohol syndrome 2
Fetal alcohol syndrome 2 Fetal Alcohol Syndrome A pregnant woman's lifestyle ultimately affects the development of her baby. Excessive exposure to alcohol during pregnancy can inflict serious, permanent physical and mental damage on her child. When a pregnant woman drinks alcohol she is making her child drink also. In knowing how Fetal Alcohol Syndrome can be prevented, what the symptoms are, and who and what make up the risk factors fetal alcohol syndrome can be better underst...
Fetal alcohol syndrome and fetal alcohol effects
Fetal alcohol syndrome and fetal alcohol effects Prenatal alcohol exposure is a preventable cause of birth defects, including mental retardation and neurodevelopmental deficits. Since the initial recognition in 1968 of the multiple effects that alcohol can have on the developing fetus [1] and the subsequent delineation in 1973 of fetal alcohol syndrome (FAS), [2] it has become clear that prenatal alcohol exposure can be associated with a wide range of abnormalities. [3] More than 8...
False memory syndrome
False memory syndrome False Memory Syndrome When the memory is distorted, the result can be False Memory Syndrome. False Memory Syndrome is a condition in which a person's identity and relationships are centred around a memory of traumatic experience which is false but the person strongly believes is true. Increasingly in grown adults undergoing therapy come to believe they suffer from repressed memories of incest and sexual abuse. This has a devastating effect on the victim and the...
Fasle memory
Fasle memory Fasle Memory There are many models which try to explain how memory works. Nevertheless, we do not know exactly how memory works. One of the most questionable models of memory is the one which assumes that every experience a person has had is 'recorded' in memory and that some of these memories are of traumatic events too terrible to want to remember. These terrible memories are locked away in the sub conscious mind, i.e. repressed, only to be remembered in ad...
Feeding yeast
Feeding yeast Table of Contents Introduction Page 1 Experimentation Page 1 Discussion Page 2 Conclusion Page 2 Acknowledgments Page 2 References Page 3 Introduction My experiment was with yeast and the best food for it. I wanted to know what would make the yeast grow better. I used corn syrup, gelatin, grape juice and flour mixed with water. I thought that the corn syrup, which is high in processed suga...
Female circumcision
Female circumcision " A Look Into Female Genital Mutilation" "She only loses a little piece of the clitoris, just the part that protrudes. The girl doesn't miss it. She can still feel, after all. There is hardly any pain. Women's pain thresholds are so much higher than men's" (Denniston, 7). This was a direct quote from an interview of people who unquestionably accept sexual mutilations. The interviews were conducted from 1979-1994 in Sudan and from 198...
Extra sensory perception
Extra sensory perception Everyone knows about the five senses. Taste: the sense that allows us to enjoy an essential part of life, eating. Hearing: the sense that enables us to carry a conversation with each other. Sight: without this we not be able to do things we take for granted, like driving for instance. Touch: this detects pain and prevents us from injuring ourselves further. Smell: this helps us identify hazardous chemicals which stops us from burning our lungs. But what ...
Extra terrestrial
Extra terrestrial In an ever-expanding galaxy, humans cannot be the only intelligent life forms. Somewhere, in some universe exists a form of life equal, or superior to, intellectual capability and performance of humans. Many people have seen unexplained occurrences that could only be classified as alien life forms. Thousands of humans claim to have seen aliens, and hundreds more say they can communicate with them. These sitings have intrigued people all over the world, and have led to a ...
Extra sensory perception
Extra-sensory perception Just what is parapsychology? This question is often asked and the reply given is very obscure. Parapsychology is often defined as the science of the unexplainable. Extra sensory perception falls into this science and is branched off into different, but specific groups. These groups define extra sensory perception as the ability to pick up information or manipulate things that normally can't happen in everyday life. Many people have claimed an ability of extra sensory...
Eye
Eye The Human Eye The Eye is the organ of that you gives your sight. Eyes enable people to perform tasks and to learn about the world that around them. Sight, or vision, is a rapidly occurring process that involves interaction between the eye the nervous system and the brain. When someone looks at an object, what he/she is really seeing is the light that the object reflects, or gives off. This reflected light passes through the lens and falls on to the retina of the eye. Here, ...
Factors of parasitic virulence
Factors of parasitic virulence Why do some parasites kill the host they depend upon while others coexist with their host? Two prime factors determine parasitic virulence: the manner in which the parasite is transmitted, and the evolutionary history of the parasite and its host. Parasites which have colonized a new host species tend to be more virulent than parasites which have coevolved with their hosts. Parasites which are transmitted horizontally tend to be more virulent ...
Excessive alcohol consumption its effects and social accept
Excessive alcohol consumption--its effects and social accept Excessive Alcohol Consumption— Its Effects and Social Acceptance Rumors and old wives’ tales such as stress makes women heavier drinkers, divorce prompts heavy alcohol use, people drive better when they are drinking, and teenagers are the main group of drunk drivers, are being thrown at today’s society left and right in an effort to blame the other guy. With all the talk about alcohol use an...
Experimental protein
Experimental protein ABSTRACT Proteins are the macromolecules that are responsible for most of the bodily functions. By investigating an individual protein, one can be able to understand the functions and structure of an organism. Before this can be done, protein has to be separated from cell components. Using the methods of centrifugation and gel electrophoresis, not only a protein can be separated from cellular components but also from other proteins. An experiment was designed to...
Exploring the mind
Exploring the mind I am interested in what drives the human mind to make decisions, good or bad. Of all the problems in society everyone of them come back to what actions we decide to make in our life as individuals and as a society. To understand what motivates the decision making process is the first essential step to understanding if not resolving many problems in society. I think that all people have at least an understanding of why others react in many different situations because we...
Extinction of dinos
Extinction of dinos Could an exploding star have been responsible for the death of the dinosaurs? This idea has become popular again as an explanation for the disappearance of the dinosaurs. An exploding star can blast material enormous distances into space. If this material reached Earth’s atmosphere, changes may have occurred that were harmful to life. We call an exploding star a supernova. Nova is the Latin word for new, and in ancient times, when an exploding star was...
Evolution or ignorance
Evolution or ignorance Education: Evolution or Ignorance Throughout recent history creationists and evolutionists have argued whether evolution should be a part of America's public education. Whether evolution is science fact, or science fiction. Evolution being a science based on statistics has some faults, although many concepts in science or math do. The process of learning about evolution is a necessary part of a well-rounded student's education due to the fact that it is a statisti...
Evolution theory
Evolution theory Comparison of the evolution theories of Charles Darwin and Jean-Baptiste Lamarck In this essay I am going to compare the theories of Charles Darwin and Jean-Baptiste Lamarck. Charles Darwin was a British Scientist who lived between 1809-1882. He laid down the foundation of modern evolutionary theory with his concept of the development of life through the slow working process of natural selection. Darwin started to make notes about this theory in 1836 and in 1...
Evolution
Evolution Evolution is a force than nothing can escape. Communities evolve constantly and although there is no standard of where a society should be at any given moment, communities evolve individually. Then in reaction to a developing community, people grow and change. Then in reaction to people evolving the tools that people use develop. This constant evolving usually happens so gradually and slowly that it is hard to detect. As we look back we can see the evolution is a major compone...
Evolutionism
Evolutionism Evolutionism What is Evolution? Evolution is the theory that all living things in the world have come into being through a non-guided, natural process starting from a primeval mass of subatomic particles and radiation, over 20 billion years ago (History). This theory says that all living things have increased intelligence or have changed in other ways over many, many years. The theory of evolution hasn�t been around for ever. Before the 20th century, people ...
