  • Abuse Can Rewire Kids Brains - 435 words
    Abuse Can Rewire Kids' Brains Abuse Can Rewire Kids Brains This article discusses the detrimental effects that abuse can have on a childs neurological activity. Children who are abused physically and psychologically show vehement neuronal excitation when observing pictures of angry faces. Children who are not victims of abuse do not experience such outrageous levels of neurological arousal when shown pictures of angry faces. Research conducted at the Child Emotion Research Laboratory suggests that the brains of abused are wired differently from those of kids who were not abused. Perhaps this is because the abused child develops a more acute set of survival skills. The brain is simply adaptin ...

  • Alcoholism - 2,059 words
    Alcoholism alcoholism Definitions and causal factors of alcoholism Alcoholism consists of a repetitive intake of alcoholic beverages to an extent that the drinker is harmed. The harm may be physical or mental; it may also be social or economic. Implicit in the conception of alcoholism as a disease is the idea that the person experiencing repeated or long-lasting injury from his drinking would alter his behaviour if he could. His failure to do so shows that he cannot help himself, that he has lost control over drinking. This conception incorporates the idea of addiction or dependence. Formal definitions of alcoholism vary according to the point of view of the definer. A simplistic, old-fashio ...

But these data invariably fail to take account of changes in availability or use of facilities, changes in admission or diagnostic policies, or changes in the source of beverages--for example, from unrecorded to recorded supplies. In the Soviet Union a change in the internal political situation with the death of Stalin resulted in a shift from official denial that any significant problem of alcoholism existed to an outcry that its prevalence was widespread and serious, though no statistics were provided. Treatment of alcoholism The various treatments of alcoholism may be classified as physiological, psychological, and social. ...

  • Animal Behavior - 2,263 words
    Animal Behavior Biology lb Abstract Animal behavior is predictable. Their behavioral tendencies are influenced by the relationship of its anatomy to their environment. By observing various forms of life, and associating the mechanism of their abilities to perform a behavioral action, evolutionary influence thereafter, can be analyzed and deduced from that point. Introduction The science and study of animal behavior involve an enormous array of complicated factors. For instance, stereotyped responses are unlearned behavioral reactions to some environmental stimulus predicated upon an organism relationship to its physical environment and anatomy. This obviously begs the question; is the observ ...

  • Anorexia Nervosa - 1,132 words
    Anorexia Nervosa A normal female takes a stroll down the streets of Manhattan and ends up at Times Square, probably one of the most colorful places on earth, which also has an abundant number of advertisements. As this female looks up at the pictures, she can see a Calvin Klein ad. The image portrays people who are the idols of our youth; young, thin, beautiful men and women. These young people depict the"ideal" body. As this female walks, she begins to notice her own physical attributes and wonders what it would take for her to look like that Calvin Klein model. Despite the fact that the greatest majority of us could never attain these physiques, many, especially young women, deeply desire ...

I think a lot of hard-core scientists and doctors who have been trained in that data-oriented scientific approach are realizing there's more to heaven and earth than we really know about. Still, Peterson admits that empirical evidence is necessary for widespread acceptance: This is such a new area that there are a lot of studies at this point that aren't reproducible. Even though there's been some interesting work done in Japan and Germany, it's one thing to get results once. But it doesn't appear that researchers have been able to duplicate these results again. While I believe there's a scienti ...

    Biology And Human Evolution Human Biology and Evolution Humans are Alive The earliest human life form can be traced back more than 3.5 billion years ago. Humans are said to be descendants of a single celled ancestor. Although they are different in size and shape all basic functions are alike. The more complex the organization of the cell became the more successful and developed it became. As these single celled organisms developed they became known as pre-humans. We share many characteristics with these pre-humans. Some of these characteristics include the masters of heredity DNA and RNA as well as proteins composed of amino acids, membranes or bound cells and lastly controlled cell division ...

Arthritis Arthritis is also another health risk that is associated with obesity.

  • Eating Disorders - 1,123 words
    Eating Disorders 11-2-01 Eating Disorders Bulimia is an illness characterized by uncontrolled episodes of overeating usually followed by self-induced vomiting or other purging.

  • Endurance - 735 words
    Endurance Endurance plays a major role in many athletic activities. Without endurance training, many athletes would not be able to compete in their respective sports. Endurance training involves low resistance and high repetitions, but what exactly does this do to your body and how does it do it? For starters, endurance training increases the level of certain aerobic enzymes, which are needed for the breakdown of fuels to produce energy. Enzymes are proteins that speed up metabolic reactions; they release and transfer energy. Enzymes are influenced by many factors: 1) Temperature- activity is increased when the muscles are warm, therefore warming up before the actual activity is very importa ...

    For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels. The very idea that cloning could one day become reality was thought to be a scientific impossibility by many experts but on one exhilarating day, what was thought to be "purely fiction" became reality. That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average sheep. That sheep was what was going to be one of the most famous if not the most famous sheep in modern day. Dolly was this seven month old Trojan lambs name and Dolly was the first ever clone of a mammal.

  • Hormones - 1,052 words
    Hormones IntroductionHormones are organic substances that are secreted by plants and animals and that function in the regulation of physiological activities and in maintaining homeostasis. They carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they are transmitted to their targets in the bloodstream after discharge from the glands that secrete them. This mode of discharge (directly into the bloodstream) is called endocrine secretion. The meaning of the term hormone has been extended beyond the original definition of a blood-borne secretion, however, to include similar r ...

    In his poem, To Sleep, Wordsworth talks about how he can't seem to fall asleep. He never tells us why, but maybe it's because he doesn't know. There probably was a significant event that he experienced that has either affected him psychologically that he doesn't know would affect him, or he has opted to not tell us about it. Either way, his insomnia isn't an uncommon thing. Insomnia is a condition in which a person has difficulty getting sufficient sleep. About 30 million people in the U.S. suffer from insomnia. It can be caused by a variety of things: overactive thyroid gland; diabetes; violent muscle twitching; drinking caffeine-containing beverages before going to bed; and painful arthrit ...
