Stem cells are the mainly mesmerizing areas of environmental science at the moment. Nevertheless, study on stem cells tends to...
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...
The video concerns the connection between sleep, the brain, and waste disposal. The body’s biological system processes create the problem of waste disposal. A constant supply of nutrients is crucial for all body parts to function. The brain comprises only 2% of the body’s mass but consumes 25% of its...
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...
Introduction Living cells undergo a process called transpiration, and produce byproducts that are harmful to the cell. One of the byproducts of cell metabolism is hydrogen peroxide. Excess hydrogen peroxide is toxic to living cell. Therefore, it must be disintegrated into less toxic substances so that it does not damage...
Abstract In this paper, specific conditions for palladium as well as silver deposition were determined. Also, the simultaneous, co-deposition of the same was determined for hydrazine-based solution bearing both element precursors. The electroless plating kinetics for simultaneous, co-depositions for both elements in the mixture were determined. Moreover, a mathematical model...
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...
“Is wolves’ coming back to Colorado beneficial for citizens?” is the main research question for this project that has to be thoroughly discussed and analyzed. The history of gray wolves in this state can be traced back to the middle of the 19th century. A wolf was recognized as a...
Soil consolidation is a process by which there is a decline in the volume of soil due to a reduction in the level of water. The one-dimension theory was established hence changing the definition which was previously associated with clay sediments. Gurjar (2018) suggests that the applied pressure that causes...
Looting and smuggling of illegally obtained artifacts have become a major problem for various branches. In terms of archaeology, this tendency prevents experts from examining the items, hiding important findings from professionals. In addition, looting receives the attention of the world’s governmental services, as it is criminal activity related to...
Introduction Bacteria are minute single celled organisms that live around and inside our bodies.They are so small that scientists often use microscopes to view and study them and each bacterium is estimated to be a micrometer long in size (Bauman & Tizard, 2004). Bacteria just like any other living organism...
Cretaceous period was the longest segment of Mesozoic era that lasted for almost 80 million years. Cretaceous period is the last section of the Mesozoic era. The first angiosperm and pollinating insects were noticed during this era, and the emerging of angiosperms and pollinating insects is intimately linked (Field et...
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...
Evolution explains the emergence of different species on earth and the respective functions of their structures. Lungs are among the organs highly studied by paleontologists to understand the divergence of organisms over time. Charles Darwin, the father of evolution believes that lungs evolved from gas bladders in lower vertebrates, precisely...
The article about the heart shows its representation, including the respective parts. The parts of the heart include the arteries and veins that take blood into and out of the heart. The article describes where the heart lies within the body system and how it functions within the body to...
Introduction The evolutionary relationship between organisms has been measured and monitored using DNA and proteins from these organisms. This is because, members of the same species have the larger fraction of their genes (DNA) and proteins being common. Genes and products of genes (proteins) can be considered as historical documents...
Introduction DNA cloning and sequencing is one of the most essential techniques in molecular biology. This involves the insertion of a fragment of DNA into a vector, for example, a plasmid in order to create a new recombinant molecule (Stark, 1987). The green fluorescent protein (GFP) is a protein that...
In group 8 and period 4 of the periodic table lies a chemical element by the name iron with 24 as its atomic number and Fe as its chemical symbol. It is classified under first transition series metals and is silvery in color with an atomic mass of 55.847.iron is...
Mutation versus polymorphism Although both mutations and polymorphism occur due to changes in DNA sequence, mutations are rare and lead to abnormal alleles. In other words, a mutation can best be understood and defined as a change in the DNA sequence that occurs in a small portion of the gene...
The collection of like cells that have an identical origin which carries out a definite function together is what I am. I can only exist if there is a cellular level organization that is intermediate between cells and an organism (Starr, Beverly 67). These cells have similar functioning even though...
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...
The Silurian period lasted from 443 to 417 million years ago. When the ice finally melted, ocean levels rose and the sea flooded vast areas of land, resulting in a milder climate. The Devonian Period (417 – 354 million years ago) was the time of the greatest cataclysms on the...
Background & Purpose Endomitosis is a variant of the cell cycle that leads to the production of up to a thousand copies of the genome. During this process, the cell does not divide but the chromosomes increase in size as the number of copies of genes increases. The purpose of...
Neurotransmitters are specialized cells that function to transfer information from one nerve, gland, or muscle cell to another. Across the membrane of the neuron cells, there is a difference in charge termed as the membrane potential. Neuro resting potential is the electrical potential difference of the membrane in a non-excited...
Abstract Microbial resistance to antimicrobial agents is a growing challenge for the development of chemotherapeutic agents. E. coli is a Gram-negative bacteria that contain pathogenic strains that lead to various illnesses including infections of the respiratory system, urinary tract and gastrointestinal system. Previous studies have reported that small molecules are...
This article’s purpose is to evaluate possible harm and advantages of GM fish. At the beginning of this article, the author notices that the twentieth century’s green revolution may have been the most significant improvement in people’s lives (Muir, 2004). However, there was an enormous increase only in agriculture; as...
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,...
