Modern rhinos, represented by a one-horned Indian rhinoceros with a pointed upper lip and a two-horned African rhino with a wide rectangular mouth, are pitiful remnants of a rich in species group of mammals. Many skeletons, bones, and teeth left from their predecessors in the...
Designing an effective method for data collection is essential for without data no research can be fulfilled. Still, very few statistics textbooks pay attention to data collection methods and issues (Bauer, 2009). Therefore, it is advised that healthcare decision-makers must be well acquainted with the art and science of data...
Introduction The aim of this experiment was to prepare a stereoisomeric mixture of secondary alcohols from the reaction of cis and trans 2, 6-dimethylcyclohexanone with sodium borohydride. 2, 6-dimethylcyclohexanone is a mixture of cis and trans isomers each containing a ketone functional group. The cis:trans ratio of 2,6-dimethylcyclohexanone used in...
Introduction The term Kinesin refers to any motor protein that is often found in eukaryotic cells. “The term defines a broad class of motor proteins which move along microtubule cables powered by the hydrolysis of ATP.” (Rogers 2010) This active movement of “Kinesins supports several cellular functions which include mitosis,...
The development of natural science challenges the tenets of already existing theories. Today, with the help of new technologies and modern approaches, researchers are able to formulate more sophisticated ideas that affect previous discoveries. Darwin’s theory of evolution is one of the ideas that was influenced by the developing field...
To identify the best way to educate elementary-age children in mathematics, a researcher decides to conduct a pilot study among fifth-grade children throughout a school district. The researcher thinks that fifth-grade girls do better in small class sizes while boys perform well in larger classes. The pilot study involves classroom...
Research Area My main area of research will be in the analysis of the performance of the various features of business organizations in a selected area. This entails the use of data from the field to produce results and consequently, carry out analysis on the same to make conclusions and...
The dangers of tuberculosis (TB) still form a reality for a large segment of the global population, as it cannot be called a “disease of the past,” unlike bubonic plague, for instance. TB continues to represent a growing threat, as around 2 million people become its victims annually (Gengenbacher and...
Introductions A reasonably new hypothesis as regards the demise of the universe gives a depiction of phantom energy ripping planetary bodies in space and ultimately all fragment of matter in an unbelievable end to time. Based on science it is just about the most revolting idea ever conceived. This study...
In vitro fertilization (IVF) is a form of fertilization that occurs outside the body in which egg cells are fertilized by sperm cells in a specially prepared fluid medium. Following the fertilization of the egg outside the body, the zygote is implanted into the womb of the mother. If both...
Introduction PCR is a biotechnological invention that is used to analyze genetic material and synthesize copies of the same. It analyses the very tiny fragments of genetic material including the damaged material to a level which can be easily studied. For the past hundred years, PCR has been the most...
Many scientists tried to understand what consciousness is and how it interacts with the world, and Anil Seth, in his speech, also talks about his findings on this topic. Seth (2017) says that people hallucinate all the time, and the images that they perceive as reality are formed by the...
The purpose of this work is to analyze the nature and behavior of cochlear nonlinearity and two-tone suppression under different conditions and at different levels. These processes may happen in the inner ear and cause certain problems with the perception of information by people and other human beings; this is...
Introduction Combinatorial chemistry is a new technique found by scientists mainly for the process of discovering drugs. It is a technology for carrying out simultaneous synthesis as well as testing of hundreds and thousands of compounds of related structure in a single container. Traditional chemistry is usually marked by the...
Molecular biology, along with ‘GenBank’ plays an important role in genetic disorders. More than 200 single-gene disorders have been detected. It determines the molecular genetic defects in various diseases. These include amongst others cystic fibrosis, sickle cell anemia, and thalassaemia. Modes of inheritance are essential knowledge in genetic counseling and...
About Non-Parametric Procedures The most common reasons of selecting a non-parametric test over the parametric alternative Non-parametric tests are preferable over parametric tests in case the data has violated the assumptions of normality (data does not have a normal distribution). Non-parametric tests are also preferable over parametric tests if the...
Introduction The U.S. Bureau of Labor Statistics (2018a) published a short article that reports the results of the analysis of the changes in the “nonfarm payroll employment” in metropolitan areas “for the year ending February 2018” (para. 1). The article does not include a detailed description of the study that...
Introduction Biological evolution refers to descent with modification. Biologically, descent is taken to refer to the concept of passing traits from one generation to another while on other hand modification is regarded as the change in the composition and frequency of the gene.This is the concept through which the modern...
Prokaryotes are organisms that lack a cell nucleus or any other membrane-bound organelle, while Eukaryotes possess both. The nucleus is one of the most important structures required in living organisms. The nucleus can be thought of as the ‘brain’ of the cell. Mostly Prokaryotes are single-celled or unicellular, except the...
The human race is a question that arises naturally due to the desire of man to divide society. Such methods have always existed, first of all, consisting of external signs, such as hair, skin or eye color, particular physical or mental abilities. Humanity has always been divided into specific groups...
Case Descriptive Statistics Statistical parameters and measurements are employed in analysis of various sets and types of data. These approaches cut across all fields of study and in most cases statistically significant findings are extrapolated in designing policies (Campbell, Machin & Walters, 2007). In the medical arena, data may be...
The opium poppy (Papaver somniferum) also known as bread seed poppy is a flowering plant. The plant can reach 3-16 feet tall with lobed silver-green foliage and blue-purple flowers that are approximately 5 inches wide. Seeds are held in a spherical capsule topped by a disk with the stigmas of...
Questions can be asked to fill information gaps or contradictions by the person directing them. Reasons for asking a question may vary depending on the relationship between the person asking and the person expected to answer. For example, a teacher may ask a question to extract information or assist the...
Introduction Methicilin Resistant Staphylococcus aureus (MRSA) is a bacterial strain that is resistant to beta-lactam antibiotic penicillin. It is also known as multidrug resistant Staph. In the hospital set up, patients who make use of invasive devices, have compromised immune system, and have open wound have greater chances of getting...
Introduction Symbiosis between marine Cnidarians (coral reefs; Order Scleractinia) and unicellular photosynthetic dinoflagellates (algae; genus Symbiodinium) is a common feature of marine biota. While Cnidarians feed on zooplankton and supply the dinoflagellates with assimilable nitrogen, phosphorus and carbon, in turn the dinoflagellates, commonly known as zooxanthellae, derive photosynthates notably glycerol,...
Foremost, the implementation of research is intended to have a developmental impact through quality improvement across the board, that is, within the economic, social, political as well as technological dimensions of any particular profession or industry. Energy resource has the pivotal role of powering other sectors. However, the global concern...
Radiation results from the decay of unstable nuclei to give out particles that could destroy normal tissues leading to diseases such as cancer. Radioactive elements are referred to as ionizing radiations that can impact the chemical and physical traits of the molecules they are exposed to. Radiation comprises high-energy particles,...
