Question One
Review of the most Recent Research on the Biology of Sexual Orientation in Mammalian Males and Females
The most fundamental question that most people do ask themselves about sexual behavior is about attraction and arousal. People have been asking themselves why someone is attracted to one another. Many people have been asking themselves why men are attracted to women and women are attracted to men, and men are attracted to men, women attracted to women. Most of researchers have never agreed on what could be the possible cause of this act. Others have blamed it on sexual orientation and others have connected to biological factors like genes and chromosomes. Most people are of the opinion that sexual orientation which is all about homosexuality and heterosexuality is determined by factors like social constraints and educational background. There are other studies that have pointed out that prenatal factors have played an important role in influencing humans sexual attraction or sexuality. Sexual orientation is described as is a sexually differentiated trait and statistics has it that 90% of men are sexually attracted to women and the vice versa is true. To begin with, in mammals both males and females, sexual orientation is organized during early life by what is known as sex steroids. Two kinds of evidence that support this argument has been founded that support this notion. To begin with, many sexually differentiated behavioral factors, morphological or physiological traits are greatly different in homosexuals and heterosexual people. This is because some of these traits are widely known to be organized by prenatal steroids which consist of testosterone hormone. These variances or differences show that homosexuals, averagely, were exposed to unusual endocrine conditions during the early stages of their development. The second evidence to support this notion, it is about clinical conditions that are associated with important endocrine alterations during the development of embryonic life normally result in an increased cases of homosexuality. From those two evidences, it can therefore be concluded that prenatal endocrine surrounding has a critical role in determination of human sexual orientation. However, it is important to note that the huge variance in this behavioral trait has remained unexplained to date. Finally, when explaining human sexual orientation, it is important to recognize that genetic differences can affect behavior directly or by altering embryonic hormone secretion or an action may be involved.
Question Two
Review of latest Research about the Science of Sleep
Sleep plays an important role in the development of both animals and human beings. This paper will be reviewing the science behind sleep. For many years, people have been trying to discover the meaning of dreams, but they have found answers to their concerns. Early civilized people used think that dream was a medium of communication between the people on earth and that of gods. There have been so many theories that have been established to explain the science behind sleep, but answers have not been found. Technological advancements have enabled for the development ...
