treatment of the disease have been investigated in science and medicine for hundreds of years‚ and‚ since the discovery of the parasite which causes it‚ attention has focused on its biology. These studies have continued up to the present day‚ since no effective Malaria vaccine has yet been developed and many of the older antimalarial drugs are losing effectiveness as the parasite evolves high levels of drug resistance. As malaria remains a major public health problem‚ causing 250 million cases of fever

(Christen‚ Fent‚ & Mittner‚ 2016). The economic value behind bees is enormous‚ because of it‚ scientists were quick to find the culprit: Colony Collapse Disorder (CCD). It consists of a myriad of obstacles facing the bees population; from pesticides‚ parasites‚ climate change‚ to the monoculturalism of crops. With these barriers‚ scientists are also researching ways to combat CCD in order to save the bees and agriculture. Colony Collapse Disorder

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

Unit 20 – Causes and Spread of Infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria are microbes with a single cell. There is no nucleus or membrane within bacteria‚ making its structure simpler than that of other organisms. Instead‚ the genetic information is contained in a single loop of DNA. Viruses are microscopic organisms consisting of genetic material surrounded by proteins‚ lipids‚ or glycoprotein coats. Fungi can be multicellular or single celled
