Substances such as metals, their sulphides, and other halides, for example, cannot be easily mixed with the dispersion medium to form a colloidal solution in this manner. To create their colloidal solutions, they employ several unique techniques.  Sols that are lyophobic are referred to as lyophobic sols. All colloidal solutions, regardless of their composition, have […]

HIV/AIDS severely impairs the body’s immune system. It kills infection-fighting white blood cells. An HIV/AIDS patient is at risk of contracting opportunistic infections (OIs) due to a weakened immune system. OIs are dangerous infections that feed on the body’s weakened immune system.

Sugars are an essential source of energy for living organisms. Monosaccharides are the simplest sugars as they are single monomeric units. We will further read in detail about this in this article. Simple sugars are made up of glucose and fructose. They are very sweet. When this glucose and fructose combine, the result comes the

Humans and animals both consume proteins which are a source of nitrogen and its essential amino acids from which they build new structural and functional enzymes and hormones. These proteins enable them to survive. The extreme conditions where the proteins may also be used as a source of energy entitles their sustaining power in the

Increasing food demand is a result of the continuous increase in global population, which is increasing alarmingly fast in response. In order to meet the nutritional needs of the current population, standard agricultural and animal husbandry approaches have proven to be insufficient. The effect has been malnutrition as a result of a lack of protein

Biosafety issues are majorly concerned with the policies, procedures, and principles adopted to protect the human population and the environment from biological hazards. If you wonder about the importance of biosafety, it is to keep an eye on harmful agents such as chemicals, toxins, viruses and radiation that can potentially wreak havoc when used amateurishly

Introduction Kingdom Monera comprises unicellular and prokaryotic organisms, specifically bacteria. The term ‘Monera’ means ‘single’ or ‘solitary.’ H.F. Copeland first coined the term in 1866. R.H. Whittaker placed Monera as the first and most primitive kingdom in its highly acceptable five-kingdom classification. The organisms of this kingdom are prokaryotes, i.e., they lack a well-defined nuclear
