Active teenagers should also take into consideration how smoking can effect their performance. It decreases your lung capacity, causing you to breathe more heavily.

.... or separated. Surprisingly, less than one percent of abortions are the result of rape. Many women regret having abortions and wish they would’ve let their child live. Still, others are relieved. Many people believe that abortion is not morally wrong. These people don’t believe that a fetus is a human being. They also believe that a mother has a right to choose what goes on with her body. These people are said to be pro-choice, because the right for a mother to chose is their main argument. There are also some special cases in which pro-choicers believe that abortions are acceptable. One of these special cases is when the mo .....

.... murder. In today's more industrialized societies, technology has simplified the abortion procedure to a few basic and safe methods. Technology, however, has also enhanced society's knowledge of the fetus. Ultrasound, fetal therapy, and amniocentesis graphically reveal complex life before birth, and it is this potential human life that is at the heart of the debate. In order to form an opinion on this matter, we must first question and define several common factors which are numerously debated. I. When does human life begin? Scientists identify the first moment of human life as that instant when a sperm cell unites with an ovu .....

.... The chances of getting into a car accident while using a cellular phone is nearly equal to the chances of having an accident while slightly drunk.� (Kolata, par.1) The distractions caused by talking on the phone are causing more accidents as the amount of cell phones being used increases. “The risk (of accidents) gets even greater if the person is discussing something important or especially is in the middle of an argument.� (Kolata, par. 2) The solution to cell phones in the cars is that cell phones should only be used in cases of emergencies. The chance of brain tumors also increases with the usage of cell phones. Radia .....

.... to confirm this belief, he removed the gonads from embryos, prior to the onset of phenotypic differentiation. All resulted in female phenotypes. The male phenotype is induced and will not manifest if the proper secretions are not made from the testis. Although the article fails to mention how, "Jost deduced that two secretions from the fetal testis are essential for male development - Mullerian-inhibiting substance and androgen." The mechanism in which spermatogenic tubules form Mullerian-inhibiting substance is still unclear to scientists. Problems with improper levels of this hormone result in genetic and phenotypic reproductive dis .....

.... "murderers". But the biggest mistake they make in their assumptions is that "pro-choice" does not mean "pro-death." Having to deal with an unintended pregnancy is possibly one of the most difficult challenges a woman has to face. Having a child is a huge financial burden on a woman as well as her family. Many women lack sexual education, such as which contraceptives are available to them, where to buy them, and how to pay for birth control, which can be very expensive.(Small steps are being made to help with the latter problem. Recently, Maryland became the first state to offer insurance coverage for contraceptives.1) These women who .....

.... is when a brain cell releases a signal to another brain cell. The signal then returns to the first brain cell. The signal is called a neurotransmitter. One major neurotransmitter is called dopamine, which is involved in feelings of pleasure. When the drug is released into the brain, it blocks the dopamine from returning to the first brain cell. Repeated use changes the brain cells so that normal messages can't be sent between brain cells. The drug must always be present in order for neurotransmissions to take place. The user is only able to feel pleasure from the cocaine rather than the things he/she used to find pleasurable. This is .....

.... of bed easier. A person who is in shape will also sleep better then an out of shape person, and feel more revitalized in the morning. Muscles account for approximently 35% of the body weight in women, and about 45% of the body weight in men. With over 600 muscles covering the human skeleton muscles give the body bulk and form. Then human body contains millions of muscle fibres whose coordinated contraction cause the whole muscle to contract. Muscles are the foundation on which our bodies are built. Without muscles our bodies could not perform the simplest tasks such as opening our eyes, talking, breathing and even the pumping of our h .....
