Protists Protists are a very large‚ diverse group of organisms‚ including the plant-like protists (algae)‚ fungi-like protists‚ and the animal-like protists (protozoans). They are all eukaryotic‚ and most are unicellular. Traditional taxonomy of protists (Kingdom Protista) did not accurately represent evolutionary relationships‚ so the classification of this group is unsettled. Modern taxonomy has rearranged the group formerly known as Kingdom Protista‚ separating the different types of organisms

HEMOFLAGELLATES characterized by the presence of a large mitochondrion known as a kinetoplast. the kinetoplastida assume different morphologic forms depending on their presence in vertebrate hosts‚ including humans‚ or their insect vectors . 2 genera important in human disease: Trypanosoma Leishmania transmitted by arthropod vectors and have animal hosts that serve as reservoirs. Amastigote stage spherical‚ 2–5 μm in dm and displays a nucleus and kinetoplast. no

Zambia is a country like any other prone to a wide variety of natural and human-induced hazards and disasters. Phenomena such as floods‚ extreme wind speeds‚ earthquakes‚ mudslides‚ droughts‚ wildfires‚ pest plagues‚ air and water pollution cause extensive losses to livelihoods and property‚ and claim many lives. This study attempts to bring to light disasters or hazards‚ there examples‚ as well draw attention to the challenges faced by the government of Zambia in controlling the disasters or hazards

r/K Strategists concept Alan Soffan In nature insect makes adaptation known as adaptive stategy as a result of selective environment factor acting in a population (Horn‚ 1976). They need to have certain strategies for efficiently utilizing the available time and energy to maximize their own survival (Atkins‚ 1980).There are two extreme strategist applied by insect in adapting theirself in certain environment.

Introduction Wildlife refers to non-domesticated free ranging animals in their naturally associated environment or habitat which includes terrestrial vertebrates‚ mammals and birds. The wildlife product we chose as a group is the Cape buffalo which is known by some people as the African Buffalo. 2 The group met on four consecutive occasions and the medium used for our research was all internet based. Thus the Google search engine was used throughout. This project would bring to bear the

Chapter 1 Physical Context of African History: Geography and Environment 1. Although some may think of Africa as being of a single climate and terrain description‚ in reality a wide variety of land types can be found throughout Africa. How does this wide variety of climates and physical terrains affect human life and settlement patterns on the African continent? Different terrains and climates allowed for different lifestyles for Africans in different regions. Those close to the sea were
