For example, young adults, who have low normal levels of human sex hormone, Testosterone tends to perform quite successfully on spatial tests, when compared to the ones with high normal levels. (Kimura, 2001). These fluctuations in the hormone levels could occur throughout the year, with higher levels happening in the autumn and lower levels in the spring, thus improving the subjects’ performance on spatial tests in the spring. On the other hand, women’s estrogen hormonal levels tends make quite effective in person-oriented occupations and functions. Unlike, the impact of seasons on the hormonal changes in men, women’s hormonal levels fluctuate around across the menstrual cycle, thus impacting their performance during those periods. (Kimura, 2001). Because of these biological differences in the hormonal levels, it is clear that women tend to gravitate towards fields like education, nursing and social work more often than men. (Kimura, 2001). On the other hand, although, men and women are equally represented in the other health-related professions, in most cases men tend to perform better in the science fields. These differences in the hormonal levels also impacts men and women’s susceptibility to certain diseases, and which indirectly impacts their behavioral patterns. That is, according to United Nations Economic Commission for Europe, estrogens offer women of reproductive age some protection against cardiovascular diseases. That is, before the age of 65, heart disease is one of the leading causes of mortality among the men, but on the other hand, cancer causes death mainly in women. After menopause and due to the hormonal changes in the women’s physical body, a kind of reversal takes place, with women facing a higher risk of cardiovascular diseases than men and in turn, men face higher risk of cancer than women. (United Nations Economic Commission for Europe). With the most important risk factors for cancers being tobacco smoking and diet,

Additionally, struggle for existence occurs and leads to saving of character that seems profitable to the individual. Finally, the preserved character is favored to pass to the next generation. In addition, Darwin insight on the struggle of existence was also essential in the process of evolution.
Those variations that are better suited to survive in a particular environment are selected by nature through the process of natural selection. These organisms in turn produce offspring’s with similar traits and better adaptation to survive. This contributes to the process of evolution.
To begin, the world functions on a delicate balance which is partially maintained by its various climates and weather patterns. The arctic is a virtual block of ice maintained by its distant proximately to the equator.
The carboxyl group of one amino acid is linked to the amino group of the next, and so on. This chainlike molecule, which may range from 50 to several hundred amino acid subunits, is called a polypeptide. A protein may be made up of a

Pneumonia is an infection of the alveoli. Tissue fluids accumulate in the alveoli reducing the surface area exposed to air. If enough alveoli are affected, the patient may need supplemental oxygen (Kimball, 2007). Below is an illustration of how pneumonia
