In 2008‚ the world experienced one of the greatest numbers of deaths from natural disasters. Some of the contributing factors included extreme weather brought about by climate change‚ as well as urbanization in vulnerable areas. The urbanisation phenomenon is a feature that is being shared by all cultures across all continents on the globe‚ it not so much a result of higher birth rates in urban areas as it is of the continuous migration of people across regions as they are lured into urban areas

Campbell’s Biology‚ 9e (Reece et al.) Chapter 31 Fungi Though fungal divisions have traditionally been based on modes of sexual reproduction‚ molecular considerations are becoming more important. Consequently‚ no emphasis has been placed on the vagaries of sexual and asexual reproduction among various fungi in this Test Bank. Instead‚ new questions assess students’ abilities to think logically about fungal morphology‚ genetics‚ and ecology. Two new sets of scenario questions deal with the biology

(World Health Organisation) African Region. Most deaths occur among children living in Africa where a child dies every minute from malaria.1 Malaria is caused by Plasmodium parasites. The parasites are spread to people through the bites of infected Anopheles mosquitoes‚ called "malaria vectors"‚ which bite mainly between dusk and dawn. There are four parasite species that cause malaria in humans: Plasmodium falciparum Plasmodium vivax Plasmodium malariae Plasmodium ovale. Approximately half of

The Search for better health – notes on all parts except first hand pracs • Discuss difficulties in defining the terms health and disease. Health is defined as the complete physical‚ physiological‚ mental and social wellbeing of an organism. It is not merely the absence of disease. Disease can be defined as a state which prevents correct functioning or impairs bodily function. It is difficult to define these terms as they are very subjective and dynamic‚ i.e. they differ from person

CHAPTER 1 THE PROBLEM AND ITS SCOPE Rationale of the study There are more than 3 000 known mosquito species. However‚ of the 150 species that are potential vectors‚ only 30 are considered dangerous. The three genera Anopheles‚ Aedes and Culex‚ from three sub-families‚ are disease relevant. The epidemiology and the life cycle stages demonstrate the importance of climatic factors and that water is the essential environmental component for mosquitoes. The immature
