Tobacco smoke contains more than 4000 poisonous chemicals including nitrogen oxides, hydrogen cyanide, tar, ammonia, metals, and various radio active compounds. Smoking increases the heart rate of the smoker and can increase the blood pressure also (Gould 2000). Tobacco smoke contains carbon monoxide which will block the necessary oxygen to the body tissues. Tobacco companies add ammonia into cigarettes which makes the brain absorb nicotine more vigorously than how it normally absorbs. Additives in the cigarettes increase the ‘free’ nicotine level of the cigarette which will enhance the addictive nature of the nicotine (Eysenck 1999).

Psychology - Research Paper Example With regard to these chapters, this paper assesses the role played by nature in a child’s development. Many scholars argue that genetics determine human development (Kendra 2). Genes determine heredity and every individual has genes from his or her parents- mother and father. These genes are responsible for determining characteristics such as skin colour, height, weight and the colour of one’s hair. They also determine how a person acquires cognitive skills as well as directing the mental processes and physical features. Genes are passed from one generation to another. The two main types of genes-dominant and recessive, determine a child’s physical look. They also influence the rate at which a child grows (Gilbert 22). Therefore, children may start doing some activities earlier than others depending on their genetic characteristics. For instance, some can begin sitting without assistance by the age of 6 months. This may be delayed or may come early in other children. Genes are also responsible for genetic disorders such as cystic fibrosis and cerebral palsy (Kendra 7). If a parent has such disorders, they are likely to pass them onto their children who will also do the same to the future generations. However, the environment under which a child grows also largely determines the physical and biological development of a child (Berger 50). A foetus that is exposed to chemicals and pollutants develops in a different manner compared to one that develops in a clean womb (Kendra 9). For example, Fetal Alcohol Syndrome caused by exposure of a foetus to alcohol while in the womb leads to physical as well as cognitive malfunctions. Nutrition influences physical and social development (Gilbert 41). A well fed child grows up to be healthy and enjoys all childhood activities. On the contrary, a poorly fed child is weak and may not enjoy what other children do since play and learning is hindered by malnutrition.
