One useful qualitative determination practice is to measure the melting point for a substance since this characteristic is considered unique. Thus,...
Introduction Physicochemical studies of key biological molecules are an essential part of laboratory practice to better understand their structure and identify possible patterns. The idea behind this work was to determine the viscosity of DNA molecules. It is well known that DNA is a long biopolymer consisting of four different...

It consists of a body, flat panel display (LED display), draft shield, door handle, four-level adjustment feet, and buttons. The vital part is a balance pan, on which weights can be put. Analytical balances are common...
The state of Ohio, sometimes nicknamed Buckeye State, is located in the midwest of the United States. It is bordered by Pennsylvania, West Virginia, and Kentucky. Across the Ohio River is Indiana, Michigan, and Lake Erie (Fact Monster, 2021). The state is formed by mostly flat land with some hills...
Glycolysis is a biological term used to describe reactions that extract energy from glucose by dividing it into two three-carbon molecules named pyruvates. It is an old metabolic pathway found in most living organisms (Chandel, 2021). The term glycolysis is derived from the root of two words, namely glycol, which...
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...
Short tandem repeat (STR) is a molecular biology tool mainly exploited in forensic science in order to determine certain locations known as loci present on the nuclear material, DNA. STR sites exhibit remarkable polymorphism which offers a reliable platform for forensic investigations to differentiate the DNA profiles from one individual...
The nerve cell is a eukaryotic cell found in the central nervous system of the body. It is the cell through which nerve impulses from different body parts are transmitted to and from specific cells to facilitate the body’s functioning. These impulses are sent in the form of nervous signals...
Abstract All animals depend on their taste or smell senses, as functionality for locating and choosing food – whether the foods are animal, plant or other compounds. This function is made possible by chemoreceptors, which are located at the taste buds of the tongue, especially, for humans. Inquiries into the...
Comparison between tachyzoites and bradyzoites During the various stages of a lifecycle, a parasite goes through various cellular stages that are characterized by different morphology, behavior, function, and biochemistry. Tachyzoites and bradyzoites are stages in the lifecycle of T. gondii. In each of the stages, the parasite differs in shape,...
My item of choice is a ballpoint pen. This item is of interest to me because for decades, we have come to rely on it as a writing material. Although we are now living in the computer age, the ballpoint pen is still popular. The ballpoint pen is a simple...
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...
Introduction Cancer is one of the main causes of death in most parts of the world, especially in the Western World. It is the second killer in the USA and in a number of European counties after cardiovascular diseases. Cancer is an abnormal growth of cells that results from changes...
Skull – consists of cranial and facial bones Cranial bones – these contribute to the cranium, which encloses & protects the brain; note they are separated by jagged boundaries called sutures; there are 8 cranial bones (note there is a right & left parietal and a right & left temporal;...
My favorite taxon is rhinoceros. 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...
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...
Jaw reflexes are of different kinds, including the jaw jerk reflex, the myotactic reflex, the jaw closing and opening reflex. This paper will aim to describe each in turn, with the clinical relevance of the normal and abnormal reflexes along with published scientific research in dental journals that has focused...
The incidence of malaria has been increasing at an alarming rate. Nearly 3000 million people are reported to be affected annually and 1/3 of them die. Confronting malaria has achieved good progress in the elimination of mosquito species that would carry Plasmodium parasites by eradiation of breeding grounds and using...
Introduction The study of the structure of DNA is important not only to biologist, but to every inquisitive mind and every person that is interested in knowing how this life we live is recreated. Many researchers have come up with findings which have contributed greatly to the body of knowledge,...
Introduction DNA profiling is an odd identification genetic passport that carries information about several dozen genome regions belonging to one person. DNA profiling analyzes the number of repeating elements in a selected area of the genome. The repeating part is called a tandem repeat, and the amount is variable. The...
Influenza viruses can be categorized into three. These subtypes are named as A, B and C with A type viruses infecting humans, birds, horses, pigs and other animals. The natural hosts for these viruses are wild birds. A review of available substantiation on potential transmission of avian influenza indicates that...
Background Along with Sarcopterygii (lobe-finned fishes and tetrapod offspring), the ray-finned fish Actinopterygii make up the familiar class of bony fishes, the Osteichthyans. Osteichthyans are distinct for having an air sac (a swim or lung bladder but this may be lost) and large dermal bone units on the head and...
Introduction Since the origin of humanity, humans have affected the natural environment around them. As civilization expands and its ability to harm, often unknowingly, other species and disrupt entire ecosystems grows, the question of preserving nature becomes more critical. Never has this question been more prominent than in the last...
Introduction Marie M. Daly is a well-known biochemist from the United States of America who became the first Black American woman to be honored with a Ph. D. in Chemistry. Her family was mostly education-oriented and, as a result, she quickly completed her studies at New York University and Queens...
Ice is usually considered to be a mineral that consists of hydrogen oxide. When ice is frozen at a constant pressure of 1 atmosphere the resultant effect is that it becomes less dense than liquid water by 9%. At 00c, ice has a density of 0.9167 g/cm3 compared to liquid...
Abstract Based on the fact that minerals are always made of aqueous matter, minute liquid-blebs could be collected within structures that are crystalline in nature or that have been with healed-fractures. The tiny blebs may be within the ranges of zero point one to one point zero millimeters; due to...
