What was a foraging economy and way of life like? Foraging was the leading way of lifestyle for the oldest communities across the globe. This economy did not imply a controlled source of sustenance, meaning that people had to cover great territories. Hunting and gathering were the primary activities of...
Results and Discussion The key results of this laboratory work were direct measurements of analytical signals from fatty acid esters obtained using the classical instrumental GC/MS method. Since it is well known that this technique uses a reference method, the organic methyl caprate with a reference peak value was chosen...
Project Summary Picture Summary The musculoskeletal system is an organ system made up of specialized tissues of the skeletal muscles and bones. Calcium relates to a mineral found primarily in foods, including milk, kale, and fish; it helps maintain strong teeth and bones in the body. This mineral plays an...
Broadly, archaeology scientifically studies prehistoric and historical human activities by recovering and analyzing material culture. As such, archaeologists excavate and describe past human-made objects ranging from simple tools such as stone daggers to complex structures as temples and cathedrals. On the other hand, classical archaeology has traditionally focused its attention...
Genetic engineering is the manipulation of the genes of an organism by completely altering the structure of the organism so as to come up with different characteristics of the same organism. Genetic engineering has been successfully applied in different fields with a lot of success especially in the disciplines of...
Fridell (2005, p.8) defines Polymerase Chain Reaction (PCR) as a scientific technique that is applied in molecular biology to amplify a single or specified number of DeoxyRiboNucleic acids. In addition, Park (2004, p.587) claims the PCR technique is used to produce a large number of copies of a particular specific...
For muscles to contract, the muscle fiber creates tension within itself. This tension is brought up by the action of myosin and actin cross-bridging sequence. Contraction in muscles generally means the generation of tension by the muscles with the help of neurons (Starr, Beverly 108). “The sliding-filament theory of muscle...
The success of science depends on continuous research aimed at upgrading existing knowledge. As such the biological fields of science are undertaking such projects. One such project human genome project (HGP), one of the most important discoveries is aimed at not only identifying and defining all types of human genes...
Introduction Arsenic is an element that occurs naturally. It exists in both living things and minerals. Due to its toxicity and people’s inability to notice its effects, many people have used it for many years for homicidal purposes (ATSDR, 2014). This paper discusses the toxicological and epidemiological implications of arsenic...
Introduction Strawberries are a group of perennial plants which belong to the Rosaceae family. They thrive well in soil that has good drainage, is moderately acidic (pH range 5.0 to 6.0) and require plenty of sunshine grow. They are capable of viable fruit production for a period of up to...
In a bid to develop a hypothesis and plan an experiment, I listed several things I would like to know within my surrounding; why a plant curves towards a window, why a plant can not grow towards gravity, why the lateral buds of most plants fail to develop and elongate...
Introduction Magnolia is among the largest genus flowering plants in Texas and eastern of North America. Magnolia is derived from a French botanist Pierre Magnol after discovering the plant in the Royal Botanic Garden of Montpellier in France. The taxonomic classification of the Magnolia tree is as follows: The domain...
Introduction Billions of years ago, when the dense speck expanded, the matter and antimatter should have disappeared and left nothing but energy. Still, some amount of matter remained and filled the world with numerous particles (Sundermier, 2015). Those particles circulating through the dark matter across the universe might pass through...
Introduction Enterobius vermicularis (pinworm) is the most common among all helminths in the world with a prevalence rate of 20-40 million in the United States. Treatment of pinworm infection is fairly easy and medication can be provided at all public health facilities. This paper seeks to provide an analysis of...
Introduction Chadha et al (1982) claims human Interferon alpha is protein derivative that is biosynthesized and secreted by lymphocytes under pathogenic stimulus. Allen and Diaz (1996, p.182-3) argues that the main stimulus that predispose secretion of human alpha are viruses, bacteria, parasites or tumor cells. Spiegel (1989, p.76-77) claims human...
Introduction The United States (U.S.) and Mexico are two large countries in North America, which shares several similarities and differences in various aspects. Geographically, both countries border each other; that is, U. S borders Mexico on the North. In the basis of security and criminology, corrections systems in U. S...
Introduction The term magnesium was derived from the word magnesia which is the district in Greece from which magnesium was first mined. The importance of magnesium in plants was discovered by scientists such as Mayer, Knop, Sachs, and Salm-Horstmar; and then in 1904-1902, Willstarter identified magnesium to be part of...
Introduction Biological systems contain a wide range of fatty acids in cell membranes and stored fat. In particular, the cell membrane of microbial organisms consists of a bilayer of glycerophospholipids in which the fatty acids are esterified to glycerol (Carlsson 1973, p.288). Microbial fatty acids are unique from one species...
Introduction Among many exotic and extinct fauna, thirteen species of Darwin’s finches, namely Geospiza fortis, G. scandens, G. magnirostris and G. fuliginosa harbor Galápagos Islands, Santa Cruz, and Daphne Major (Grant & Grant, 2008). According to Grant and Grant (1995), these species have displayed remarkable evolutionary adaptations to survive harsh...
The effects of environmental pollution on the global marine ecosystem, as well as local ones, have been tremendously adverse, with multiple species having become extinct or approaching the stage of extinction. Therefore, strategies for restoring the ecosystems that said organisms need to survive and thrive must be introduced into the...
Introduction Education is a vital need of modern society. It allows people to develop their skills and talents so that to further use them for their own prosperity and for the glory of their countries and continents. In Africa, the issue of education is rather burning as the weak economies...
The aim of this experiment is to show how natural enzymatic reducing agents are as effective as the chemical ones. A reduction process is characteristically the gain of two hydrogen atoms or the loss of an oxygen atom, or both (Fox & Whitesell, 2007). This results to a structural configuration...
A brain tumor is an incompletely studied disease, which, nevertheless, is dangerous for people. The tumor itself represents the formation of cancerous cells inside the brain (Kivi & Leonard, 2017). Since Mr. Mateo’s list of signs contains impaired vision, it can be assumed that the cancer is in the occipital...
Brief Theoretical Background Acid Base Interaction Chemical reactions between the molecules of acids and bases formed the foundation for the acid-base titration method, thanks to which a number of working problems related to the selection of the indicator, determination of the type of interaction, calculation of the equivalence point are...
