Coxiella burnetii is an obligate intracellular bacterium and pathogen closely related to Rickettsia bacteria, but distinguished from them by multiple extraordinary characteristics. Those characteristics include the presence of small and large cell variants with differing structures, strong resistance to adverse environmental conditions, variable reactions to Gram staining, and airborne transmission...
Introduction Folate is a naturally occurring vitamin that is part of the B complex group of vitamins. Folate, a water-soluble vitamin is converted to various active forms in the body. Folate is a general name used to refer to folic acid or folacin. Folate is a core vitamin that is...
Introduction Genes play important roles in physiological processes in the human body. Advancements in the field of biology have resulted in discoveries of essential processes with regard to genes. An example of such processes is RNA interference (RNAi), which has been found to have a role in inhibiting gene expression....
Ruscha’s rat (Abrawayaomys ruschii) and giant panda (Ailuropoda melanoleuca) were selected for the analysis of mammals. First of all, it should be stated that the similar features of all the mammals are shared among all the species, and the two selected are not an exception. The common features, which Ruscha’s...
Introduction The production and purification of proteins is a difficult and expensive task which takes time. Naturally, proteins are produced by plants and animals from their building blocks known as amino-acids. However, this is a slow process and the products are usually very limited and in small amounts which cannot...
In the wake of increasing international concern on the prevalence of lifestyle conditions, researchers have shown relentless efforts to establish the causes and prevention of Alzheimer’s disease. This essay seeks to establish various factors that a researcher must consider during the selection of existing study instruments. Factors Considered in the...
Introduction Every expectant mother wants to be sure that her baby is healthy, well-developed, and complications do not threaten the pregnancy. Modern technologies allow detecting pathologies at an early stage of pregnancy, which makes it possible to make the necessary decisions promptly. Genetic screening (prenatal screening) is a maternally and...
Description of mobile users Descriptive statistics are useful in summarizing data (Levine, Krehbiel and Berenson, 2010). Some of the most common types of descriptive statistics include meaning, mode and median (Francis, 2004). Mean refers to the average of a data sample while the mode is the most frequent observation in...
Bacteria have simple digestive systems whereby food is ingested and wastes are eliminated from the body through the cell membrane by use of the contractile vacuole by the process of simple diffusion. On the other hand human beings have a more developed digestive system with various organs being used to...
Introduction This paper provides the guidelines on how to develop a model that suits different geological formations for disposing of nuclear waste products. It includes an analysis of different situations that provides the geological understanding of the potential sites using different software tools to conduct the study. In addition, the...
CAM The patient would likely benefit from practices in the CAM domain of manipulative and body-based practices, commonly aimed at those with chronic pain. This domain includes CAM treatments such as chiropractic manipulations, massage, acupuncture, acupressure, and reflexology. Chiropractic manipulation would benefit the patient as it performs spinal and joint...
Introduction Personal Genomic Services As described above, the advancement of the SNP technology in genomic analysis has made it possible to achieve cheap, effective, high-throughput, novice and fast methods for analyzing personal genomes. The company is providing services through its program “The 23andMe Personal Genome Service”. The aim is to...
Introduction Background According to BCS (1996) interpretation of catalysis reactions can be carried out using transition state theory. The process of converting reactants into products involves formation of intermediate products that dissociate to form final products. in a non-directed reaction, a side reaction can result leading into formation of side...
Introduction The article chosen for this assignment as the example of quantitative nursing research was written by Rejnö, Nordin, Forsgren, Sundell, and Rudolfsson (2017). There are several reasons why this study is rendered as quantitative. First, the researchers, who are educators and health care research professionals, identify their study as...

The Canadian Shield (also referred to as the Laurentian Plateau or Bouclier Canadien in French) makes up almost half of Canada’s total area since it extends from Labrador through to northern Quebec, Ontario, eastern and Northern Manitoba, northern Saskatchewan and the very northeast corner of Alberta where it plunges under...
Introduction The National Zoo is situated along Connecticut Avenue in Washington, D.C. The National Zoo takes care of about four hundred species of animals. Additionally, it offers research and recreation services. Most of the animals in the park are in danger of extinction. I visited the National Zoo on 4th...
Summary Research comprehension is essential in reading a scientific article. Such writing is not accessible to most people because of the seeming complexity of structure and language. Nevertheless, works of science can be read and understood, and finding effective strategies for exploring complex texts is a critical skill to learn....
Introduction One of the areas of polyoxometalate (POM) chemistry that has had very little research is the solution chemistry of polyoxotantalates. One of the main chemical components in this area comprises the hexatantalates. The chemical species [Ta6O19]8−, which is a positively charged ion, has immense stability in elevated pH. The...
Introduction Bacterial food toxicity refers to the extent to which bacteria can damage organs of persons who ingest food or fluids contaminated with different species of bacteria that are known to cause toxicity. The concept of bacterial toxicity in food is that the biological effects caused by the microorganisms are...
