The sexual response cycle is the term used to describe the changes that occur in the body when men and women become sexually aroused. There are four stages or phases. The sexual response cycle consists of vasocongestion and myotonia. Vasocongestion causes erection in the male and swelling of the area surrounding the vaginal opening. As blood vessels dilate the testes‚ nipples and earlobes swell. Muscle tension is called myotonia. It consists of facial grimaces‚ spasms in the hands and feet‚ and spasms

Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

1. Maslow’s hierarchy of needs states that people will first attempt to fulfill basic needs such as physiological and safety needs‚ and then if those are satisfied‚ they will make efforts to satisfy other needs‚ such as social and esteem needs. According to this theory‚ only when their most basic needs have been satisfied will people be able to concentrate on satisfying higher-level needs. However‚ if their basic physiological and safety needs become threatened‚ they would then be likely to revert

Recrystallization of Benzoic acid Chemistry 204-002 Date: 4/9/2011 Hector Ortega Recrystallization is a method used to purify compounds‚ and this is a very important procedure because compounds are naturally impure. Polarity and solubility play a big role in this experiment and these characteristics are exploited in order to have a crystallization of the desired compound. In this experimented benzoic acid was crystallize using ethanol and water. I chose these solvents based on part C of the experiment

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

Spermatogenesis Spermatogenesis is the production of the male gametes (reproductive or sex cell) otherwise known as sperm. The production of sperm takes place in the seminiferous tubules within the testes and are formed from cells by a type of cell division called mitosis and then meiosis. This process begins at puberty. Spermatogonia cells are made by mitotic division of the primordial germ cell. Mitotic cell division produces diploid cells that are identical to the Parent cell with 46 chromosomes
