Sexuality at Different Life Stages Aerial Familiar PSY265 December 15, 2008 Sex is the one biological process that is completely necessary for the perpetuation of humankind. We, as a race, can eat well, sleep well, drink well, and even love well, but without the capacity to reproduce we cannot continue beyond a single generation. Yet the reproductive component of sex sometimes takes a backseat to more complicated subjects such as intimacy, love, and sexual gratification when considering sex across different stages of life. Indeed, John Barrymore (n.d.), the great profile, once quipped, "Sex: the thing that takes up the least amount of time and causes the most amount of trouble" (p. 2). However emotionally and psychologically complicated sexual intercourse might be, sex still maintains a prominent and even necessary position in human lives from adolescences, through disabilities, and into the later years.
Enzymes Introduction Enzymes, which are proteins, are produced by all living organisms. These proteins consist of amino acids but what makes them different is how they behave in our body. (Felice) Enzymes are catalysts that make biochemical reactions take place within our bodies take place quickly and efficiently. These reactions would otherwise happen very slowly and or not occur at all. (SYMBIOSIS p59)
Hybrid Embryo Research: Scientific Breakthrough or Are We Playing God?
In his article “Move Over, Oil, There's Money In Texas Wind,” Clifford Krauss writes about the growing popularity of wind turbines in Texas. It is an alternative source of energy, and many Texans are turning oil fields into wind farms. If the rate of wind turbines as a use of electrical generation keeps growing, wind power can become the main source of electricity in Texas and eventually the United States. Some drawbacks to wind power and turbines are that they are more expensive than fossil fuels, and on the hottest days, when it is need it the most, it is rarely windy. These turbines are increasing in size, and they are getting deadlier to bats and birds as the size of their blades increase. Despite the drawbacks to wind turbines, they are more environmentally friendly, and wind is also a renewable resource. Wind power is not only confined to Texas. Iowa, Minnesota, Colorado and Oregon have also started using wind turbines as a source of power. Long Island is also on the same track. Other countries have also caught on to wind power, such as Germany and Spain.
