Malaria – Stopping a Global Killer Divya Reddy | Year 12 Biology Introduction As medical technology is increasingly improving with continuous research, scientists are developing a range of medicinal treatments and cures that provide patients with exceptional care. Despite these treatments, there are constant biological diseases emerging that may be a severe threat to patients in the near future. In both western and undeveloped areas, infectious diseases are becoming progressively common and in
caused by infectious agents has had a negative effect on human culture and biology. Infectious diseases have devastated human populations all around the world from past to present. As a result of this, humans have learned to adapt to the infectious agents through the evolution of genetics. This paper will primarily focus on the production of sickle cell hemoglobin and malaria. The purpose of this essay is to analyze the research on how human genes can evolve to better survive their environment.
organisms passed on when they feed or bite. Insects are capable of spreading diseases caused by many different types of microorganisms including bacteria, viruses, protozoan and others. Mosquitoes have earned the title of "the most deadly creature on earth." This is due to the fact that they spread serious epidemic diseases such as Malaria, Yellow Fever, African Sleeping Sickness, and West Nile Virus. Malaria is one of the ten most common, yet deadly diseases in the world. It is a parasitic disease
trying to eliminate mosquitoes will not prevent malaria outbreaks. If malaria is a parasite of the genus Plasmodium (CDC, 2011) and is only present in the female population, then wiping out female mosquitoes means no procreation. As learned in previous units; disrupting the ecological cycle can cause greater damage than for the greater good. Mosquitoes are apart of the the food chain; they give other organisms, such as aquatic animals that prey on the mosquito larvae, a food source. The most common predator
cause of much mortality because of disease they spread 2. Affect on organism a. Survival and transmission i. Protozoa is able to reproduce inside humans contributing to their survival can be free living or parasitic in nature ii. Helminths also can be free living or parasitic in nature but once they reach adulthood they cannot reproduce in humans iii. Ectoparasites act as vector and remain on host for a long time B. Plasmodium 1. Plasmodium falciparum background information a. 48 hour fever
and has a "fishy" odor -Cholera has been able to be eliminated through the promotion of safe water, better hygiene, proper fecal disposal, well cooked food. Water was one of the main ways that cholera was spread since people were disposing of their species in bodies of water. Another thing that helped was better hygiene to stop transmission by touch, cooking food better in order to eliminate bacterial contamination through consumption. Steps to stop spread: 1. Monitored the epidemic outbreak
diseases are introduced to human through insects will further be discussed in this paper. This paper will attempt a further analysis on the history, the distribution of the diseases worldwide, and the further impact noted caused by the diseases. Vector could be defined as an organism that does not involve in causing disease itself, but responsible in conveying pathogens from each host to another which in this case; the insects. These diseases can be transmitted to human through various ways, and one

Disease is defined as a disorder with a specific cause (which may or may not be known) and recognizable signs and symptoms.

If so, explain the biology. How has this strange biology propagated throughout the species? The illness does not respond to any known treatments. As biologists, how might you stop the spread of this disease? Devipriya/Sarina Briefly describe the basic biology of Wolbachia. What
5. a. Dracunculus medinensis, or the Guinea worm, has plagued humanity for thousands of years. This parasite enters the human body initially as larvae from drinking water. As the worms grow older, they begin to approach the skin of the individual. The worm causes blisters on the skin that burst and cause massive pain. In order to extinguish the pain, victims jump into water; however, the water provides a better situation for the worm to reproduce, so the parasite releases larvae. In other words
