1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.

methicillin-resistant Staphylococcus aureus‚ multi-resistant Salmonella typhi‚ Shigella dysenteriae‚ Neisseria gonorrhea‚ Pseudomonas aeruginosa and multi-resistant Mycobacterium tuberculosis. The development of resistance to drugs commonly used to treat P. falciparum malaria is of particular concern‚ as is the emerging resistance to antiretroviral drugs. The mechanism of bacterial resistance to an antimicrobial agent falls under three major categories. 1. The drug does not reach its target Ex. Mutation or

Hepatitis C Cause The biggest cause of Hepatitis C contraction is when a person comes into contact with the blood of someone who already has Hepatitis C. The most common cause of Hepatitis C via blood is through the sharing of needles and other equipment such as cotton‚ spoons and water that are used to inject illicit drugs. Transmission The Hepatitis C virus is transmitted via blood. The blood containing Hepatitis C positive must get into a person’s bloodstream before transmission can

1. BIOLOGICAL CLASSIFICATION Aristotle’s classification - Aristotle was the earliest to attempt a more scientific basis for classification of organisms. - He classified plants into trees‚ shrubs & herbs and animals into two groups‚ those which had red blood and those that did not. Two-kingdom classification - In Linnaeus’ time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes

and meiofauna‚ protozoa are an important food source for microinvertebrates. Thus‚ the ecological role of protozoa in the transfer of bacterial and algal production to successive trophic levels is important. Protozoa such as the malaria parasites (Plasmodium spp.)‚ trypanosomes and leishmania are also important as parasites and symbionts of multicellular animals. Some protozoa have life stages alternating between proliferative stages (e.g. trophozoites) and dormant cysts. As

It affected a lot of wars‚ and settlements‚ such as when the new world was discovered. Most of the germs from these diseases came from domesticated animals‚ and people from the Old world.

IMPACTS OF DEFORESTATION ON MALARIA IN SOUTH WEST NIGERIA: THE EPIDEMIOLOGICAL‚ SOCIO-ECONOMIC AND ECOLOGICAL IMPLICATIONS Abstract Forest resources in Nigeria are undergoing severe exploitation pressure due to demographic growth and socio-economic development. Through the process of forest clearing‚ deforestation alters the ecology of local malaria vectors. The overall goal of this study was to seek to clarify the mechanisms linking deforestation‚ economic development and malaria epidemiology and
