Introduction Imagine yourself at the peak of adulthood, running, swimming, enjoying all aspects of life to the fullest, and being diagnosed with a fatal disease. Like a bird that soars the skies and gets shot down, that is the feeling that a person diagnosed with …
The term “wetlands” is often associated with the image of the coastal marsh – a muddy area that is teeming with a variety of animal life and emergent vegetation such as mangroves, rush and cord-grass. But wetlands are actually areas that are characterized by the …
While eagerly awaiting the end of High School, in the year 2005, my world disintegrated. I was in the last Semester of High School when I was diagnosed with stage 3 Skin Cancer. (more…)
How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope, we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% …

Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport …
Herpes Simplex Virus Type 1 Infection at the Molecular Level Research Paper Virology 24 November 2008 Abstract Herpes simplex virus type 1 (HSV-1) infection is widespread and causes significant disease in humans. The structure, epidemiology, pathogensis and immune response are examined in this review, as …
Abstract Aim This review describes recent investigations in to the impact of atherosclerosis on the vessel using four inflammatory stages eventually leading to cardiovascular complication. Research in to atherosclerosis has intensified globally as it has become one of the main reasons for increased mortality among …
Darwin was the first to suggest how evolutionoccurs. Humans belong to the primate family known as hominins. Characteristics that evolved to perform one function but were co-opted to perform another function are called exaptations. Each group of three consecutive nucleotide bases along the strand of …
Patterns of Evolution Humans alter our environment to suit our needs rather than adapt to our environment based on environmental stressors. Due to this fact, we are unlikely to be affected by the pressures of natural selection. We will not likely be affected by further …
Insecticide resistance management is not a novel idea, it have been used in agriculture and to address some public health situations over the past century(WHO, 2011b). The renewed attention to IVM enables the integration of several tools to achieve a stronger impact (WHO, 2016a). It …
Study guide for Ch 16-18 Chapter 16 • Alfred Hershey and Martha chase answered the question whether protein or DNA was the genetic material by using Bacteriophages (viruses that infect bacteria). o Bacteriaphages were good for the experiment because they only contain 2 organic compounds, …
Introduction Flavopiridol, a well-established inhibitor of cyclin-dependent kinases (CDK’s), is currently undergoing clinical trials. The inhibition of CDK’s, which are involved in the cell division cycle, is a vital goal in anticancer agents and therefore having potent drugs which can selectively inhibit these is crucial. …
Introduction Histone Proteins are favourably the alkaline proteins which are present in the nucleus of the eukaryotic cell. They are the basic parts responsible for wrapping and organizing DNA into chromosomes in the nucleus. They are the principal protein elements of the chromatin and acts …
Stephanie Saperstein ISB 201L 9. 24. 11 Deforestation and Malaria The changes in global environments is expected to affect the rate of malaria cases in humans. Malaria is a serious and at times fatal disease caused by an infectious parasite that can live within a …
Nursing Implications-?prevent secondary infection, prevent wasting syndrome from malnutrition, maintain or improve the present level of immune function, maintain adequate social functioning, and maintain or improve current mental status. HIVE-I and HIVE-2 are both retroviruses and have only RNA as their genetic material. When they …
Level 4 pathogens are quite simply, the nastiest causes of disease ever discovered. Scientifically speaking, they are organisms that cause severe diseases to humans and are serious work hazards in the laboratory. They also present high risk of epidemics and there are usually no effective …
Scientists cross breed them. Most commonly used are genetic fruit flies to study the effects of genetic changes on development. Flies are preferred over other other animals because their vertebrae are simpler than other organisms. Modified bacteria are used to produce the protein insulin, to …
Chemotherapy simply means the use of chemicals to treat disease by destroying microorganism or cancerous or tumor cells. Generally, chemotherapy acts by destroying rapidly dividing cells although the mechanism that leads to this differs. Several divisions of chemotherapy agents exist such as the anti-metabolites, plant …
Transcript Speakers: Ian Tattersall, Jonah Ratsimbazafy, Michelle Sauther, Frank Cuozzo (Rain trickling, lemur sounds: squeaking and calling) (Music playing in background) IAN TATTERSALL: I think everybody who is involved with lemurs is concerned for the future. We’re in a finite island that cannot infinitely be …
List the five characteristics all organisms on Earth share. The five characteristics all organisms share is: information, replication, evolution, cells, and energy (cerie). Explain why the first four are required for life. Cells allow things to go in and out of the organism (allows diffusion …
The cell cycle is a sequence of events in the life of a cell, including cell division. Cell division distributes identical sets of chromosomes to daughter cells. This process is used for reproduction, growth, and repair in the body. The cell cycle can be broken …
By defining the word elements, one could define the medical words. Learning to combine and recombine the word elements into medical words is an integral component for those enrolling or practicing in the medical field. Word elements include prefixes, suffixes, and root or stem words. …
Photosynthesis Essay During the Light Dependent Reactions, activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then, NADPH is able …
