Statements: A scientist wants to find out why ocean water freezes at a lower temperature than fresh water. The scientist goes to the library and reads […]

Microbiology is the study of microorganisms or microbes, which are tiny life forms that cannot be seen without magnification. These microorganisms are found everywhere and have a significant impact on the planet. The discovery made by Englishman Robert Hooke in 1665 of “little boxes” or “cells” in a slice of cork through the microscope is […]

Lloyd, Jacqueline et al., Social contextual factors associated with entry into opiate agonist treatment among injection drug users. It’s a Health publication. The primary audience of the Journal is the American public. Injection drug users or the IDUs are the second largest group that has a high risk of contracting HIV infection in the United […]

The increase in water inside the cell causes the cell to become engorged and erupt. In a hypertonic environment, water will leave the cell, as the amount of water in the cell is higher than that outside of the cell. As a cell looses water in a hypertonic environment it becomes smaller in size and […]

Food microbiology involves the study of microorganisms scientifically in food production and in food itself. All the microorganisms that lead to spoilage and contamination of food are discussed in food microbiology. These microorganisms affect food both negatively and positively. They are beneficial in that they help in production of food, for instance there are microorganisms […]

Cancer is one of the diseases which have greatly affected individuals globally. Despite that, it is true that there should be a way of keeping track of the HPV virus. Regardless of that, it is clear that this virus disappears with time on its own and it doesn’t cause widespread health problems. But in case […]

The Golden era of the study of microbiology depicts the period between the 18th C and 19th C that experienced major breakthrough in scientific discoveries of especially in the field of microbiology that took place during the Renaissance era in the Europe continent. The Renaissance period greatly remembered as a period of scientific inventions, significant […]

Introduction The focus of this discussion is the question of whether we are making the world too clean. We will explore the hygiene hypothesis, which suggests that people nowadays grow up in a cleaner and more germ-free environment. As a result, when they come into contact with a different environment, health problems arise more quickly. […]

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases – enzymes which break down agarose into oligosaccharides. This physiological class branches through genii, regardless of Gram Stain status or […]

This investigation is looking at three water samples A, B, and C, which have been associated with a gastrointestinal infection of children in a small village. In which three walls have been associated with the path of infection. The likely cause of outbreak has been identified by using a serial dilution of the samples, which […]

Hypothesis: If the most effective solution for pathogenic bacteria is household bleach, then the descending order from best to least are household bleach, Penicillin, Monoclinic, Household Disinfectant, Anti- Bacterial Soap, Erythrocyte, Sterile Filter Paper. Materials: The materials used in this lab include a agar, a Petri dish, test tubes containing the pathogenic bacteria: Staphylococcus erasures, […]

Natural cleaning, Healthy living Air, water, residual agricultural chemicals (pesticides/herbicides) and unpleasant odours (food, bathroom, refrigerator, cigarette smoke and turbid indoor air odours all contribute to our daily toxic load. Most of the solutions developed by industry for ridding ourselves of these pollutants contain additional chemicals, which increase our exposure to potentially harmful chemicals. How […]

Abstraction The subject of this research involved the happening of familial transmutation in bacteriums ( E. Coli ) . More specifically, antecedently prepared pGLO plasmid–which consisted of the cistron to be cloned–was used to transform non-pathogenic bacteriums. The pGLO plasmid contained a cistron for the Green Fluorescent Protein ( GFP ) from a bioluminescent Portuguese man-of-war […]

Extensive investigation was carried out on rheumatic fever during the early 1900s due to its high prevalence in children worldwide, leading to numerous hospitalizations. While developed nations have seen a decrease in rheumatic disease prevalence since the late 1900s, non-developed countries still struggle with significant issues related to rheumatic fever, which are now even more […]

In today’s world, the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment. It has been seen that helpful bacteria are useful in dissolving organic sludge from water, breaking down the growth of algae, reducing the various noxious odours […]

Immunization is the act of administering modified or inactivated microorganisms, such as viruses and bacteria, to enhance immunity against specific illnesses. This process stimulates the immune system to develop a defense mechanism against diseases rather than causing them. Consequently, when vaccinated individuals come into contact with disease-causing pathogens in the future, their immune system will […]

The development of recombinant DNA technology is, in biological terms a very recent discovery. It was founded in 1973 by Cohen and Boyer, the first two scientists to successfully transplant a section of DNA from one bacterium and insert it into another using restriction enzymes, creating the first transgenic organism1. As with every biological discovery […]

A ruminant is an herbivore with a multichambered stomach. The example of a ruminant that will be used is cattle. The example of the carnivore that will be used is a dog. The carnivore is a meat eating organism. The dog is a carnivore, and wild members such as wolves are predators. Refer to fig. […]

Microbe is a term for tiny organisms that individually are too small to be seen with the unaided eye. There are five main types of microbe: bacteria, archaea, fungi, protists and viruses. * Bacteria – Bacteria are not only are with us all the time, but help us do an amazing array of useful things […]

Experiencing “life on the edge”, bacteria have to respond to changes in the environment in order to survive. Facing limited resources and coupled with intense competition in almost every environment, bacteria have to accommodate any potential energy sources of nitrogen, carbon while resisting toxicity to their regulatory process and metabolism. By establishing an intra and […]

The aim of this investigation is to find out what effect out of two antibiotics, penicillin and streptomycin has on the growth and multiplication of two different species of bacteria. The two different types of bacteria we will be using are E-coli and micrococcus luteus. The Apparatus:* Four sterilised Agar plates,* Glass spreader,* Masking tape,* […]

A species is a group of organisms that have the capacity to interbreed, leading to the production of offspring that are both fertile and viable. Bulldogs, terriers, and golden retrievers, despite their different physical characteristics, are all classified as dogs because they can interbreed. Both humans and cats can interbreed within their species, but not […]
