HIV and AIDS is acknowledged as a global health crisis, for health workers, policy makers, and ordinary citizens in Africa and parts of Asia. Managing and coping with the reality and burden of HIV and AIDS is a never ending struggle. It has become part of everyday conversation in homes, working places, and social gatherings; it has also crept into lectures class notes and hence propelled itself to the top of the social economic and political agendas.

When charges move relative to each other,they experience a new force in addition to the electrstatic one.This new force is the magnetic force and can be shown to be a consequence of special relativity.

Seed industry has played a vital role in the availability of high quality seed of improved crop varieties with attendant modern power equipment, improved fertilizers, and better methods of insect and weed control. These altogether have revolutionized farming 1.1 Evolution of seed The evolution of plants has resulted in increasing levels of complexity, from the earliest algal mats, through bryophytes, lycopods, ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive, especially in the environments in which they evolved, each new grade of organisation has eventually become more "successful" than its predecessors by most measures. 1. Evidence suggests that an algal scum formed on the land 1,200 million years ago 2. To thrive and to avoid extinction, plants have made mechanisms and evolved seed plant during 200 million years ago 3. The latest major group of plants to evolve was the grasses, 40 million years ago 4. The grasses, as well as many other groups, evolved new mechanisms of metabolism to survive the low CO2 and warm, dry conditions of the tropics over the last 10 million years.

Human behavior plays a key role in most of the disease condition in life. a) Socialization; is a life long process through which individuals in a society develop an awareness of social norms and values; achieve destine of self. b) Norms: Rules and expectations conduct which either prescribes a given type of behavior, or forbid it. c) Values: Culturally defined standards held by human individuals or groups about what are desirable, proper, beautiful, and good or bad that save as broad guidelines for social life. d) The individualistic interpretation of disease places emphasis on the individual as responsible for his or health status.
