Introduction This laboratory test aimed to recognize one unknown species from a diversified culture. The researcher conducted three trials in the laboratory to ascertain the unidentified species. The experimenter’s tests include; Columbia CNA Agar, Eosin Methylene Blue Agar, and the Phenol Red Test (Vega & Dowzicky, 2017). The analyzer realized...
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...
Domestication Models Two Agricultural Theories That Oppose Each Other There are two main domestication models used to describe the development of agriculture. Some scientists strongly believe hunter-gatherers first cultivated wild plants by putting random wild seeds in the ground near their homes. The first approach supports the idea that domestication...
Photosynthesis is a chemical process used by photoautotrophic plants and other organisms to change carbon dioxide and water into organic compounds like sugars with the help of solar energy. These organisms include green plants, algae and some bacteria. The process produces oxygen and vital products as waste products that enhance...
The life of the Nacirema is rich in many rituals that shape the community and underline the role of magic. Three dominant concerns, namely the human body, the appearance, and human health, are usually mentioned in ceremonial activities. For example, the mouth fascination ritual proves the importance of the mouth’s...
Metabolomics is the study of molecules whose molecular weight is very low and is located in the cells. Metabolites are found in different species of animals and help in extrapolation after research is done in the laboratory. There are different technologies used to measure metabolome, which include spectrometry of mass...
Abstract Crystallization is a separation operation in which crystals of blended components are obtained starting from a liquid mixture (solution or molten magma-solid). In some cases, it might generate components that are 100% pure. Crystallization creates thermodynamic conditions that compel molecules to catch up and regroup it into highly organized...
Introduction There has been a remarkable breakthrough in molecular biology over the last ten years. Already today, it is possible to read the genetic code of a person and to predict what diseases it will inherit. With the help of gene technology, scientists clone animals, attempt to create children “on...
The main advantage of sexual reproduction is the fact that it introduces genetic variation. Giving new organisms half the genome of each parent means that they will be unique living beings rather than clones of their parents (Miller, n.d.). This random variation gives the species a chance to gain new...
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...
When Charles Darwin visited the Galapagos Islands in the 1830s, thirteen species of finches inhabited the place. Finches show a variety of shapes and sizes of beaks, all of which are suitable for their different types of food and lifestyles. Darwin gave this phenomenon the following explanation: they are all...
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...
A study conducted at Paul Sabatier University found that societal shifts caused ancient hunter-gatherers to prefer male horses. The research used DNA from the remains of ancient horses to determine alterations in animal husbandry preferences. The study of DNA, starting with the human genome, has broadened to allow researchers to...
The brain is one of the most complex body organs, and addressing the issues that relate to it can be sophisticated as well. The TED Talk video gives an elaborate description of the common misunderstanding of the brain like a bag of chemicals and that related ailments can be resolved...
The development of new branches within biology laid the foundation for understanding the subtle mechanisms of cell functioning in general and of its components. It became apparent that the genetic apparatus occupies the central place in a cell. Thus, a prospect of directed influence on the structure and functioning of...
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...
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...
Introduction The human body is a complex machine that has various components that play different roles to ensure people develop and grow without problems. Blood plays an important role in the body because it ensures there are efficient gaseous exchange, respiration and excretion systems, and coordination of various parts. It...
Spider Mating Ritual Research As shown in picture 1, male peacock spiders have a bright and colorful appearance, designed to attract females (Antonsen, 2019). However, their fascinating looks are only the tip of the iceberg, as these creatures have a whole slew of moves and signals aimed at gaining the...
Introduction There is no doubt that modern technologies greatly simplify human life, especially if it concerns computers and intelligent systems. Being a part of a developed digital society, the consumer integrates with existing technical solutions every day and, therefore, hardly perceives them as something fantastic. In biological technologies, the situation...
Introduction Even in the age of information and scientific developments, the theory of evolution continues to separate people. This theory supports religious separation by disproving the concept of intelligent design, according to which the complexity of living organisms on the planet makes life unexplainable and suggests the presence of an...
One of the world’s most endangered organisms is vaquita (Phocoena sinus), native to the northern Gulf of California. The animal got its name from the Spanish name vaquita, which means little cow. Scientists first identified this animal in 1958 when they found its’ unique skulls on the beach (Manjarrez-Bringas et...
Introduction Today, agriculture makes significant contributions to the development of the U.S. economy. Many industries are closely related to this field, including food sales, forestry, fishing, and manufacturing. The connection between agriculture and the chemical industry results in the creation of a new agrichemical industry with higher-yielding seeds, specific chemical...
Introduction William Foxwell Albright was an American archaeologist born in Chile. He is well remembered for his involvement in excavation of the biblical sites and his expertise in history and culture of the Near East. During his life, he conducted excavations at several places in Palestine. His most renowned work...
Introduction We are “Red Panda,” a mammalian species native to southwestern China and the eastern Himalayas (see Appendix 1). We are the only members of the Ailuridae family (we could have been raccoons but scientists opted to place us in a separate family). We live both in the wild and...
