Introduction A cell is the structural and essential unit of all living things. Scientist Robert Hooke discovered microscopic chambers in a dried portion of a cork tree in 1655 while using a simple light microscope to examine it. He named these chambers cells. The cell is the smallest autonomous component of an organism if we

The coronavirus disease 2019 (COVID-19) pandemic has infected millions of individuals. The new coronavirus (SARS-CoV-2) epidemic offers a significant health danger to the general public. As a result, early and correct detection of the virus is critical for disease treatment and lifesaving. The reverse transcription-polymerase chain reaction (RT-PCR) technology is the current standard for coronavirus

A variant of the Sydney strain is causing the norovirus outbreak in the UK. This variant was first identified in Australia and New Zealand in 2012 and has since been associated with outbreaks worldwide.

First of all, we need to know what immunisation is. Immunisation strengthens an individual’s immune system against an infectious pathogen (known as the immunogen). When this system is exposed to molecules that are foreign to the body, known as non-self, it will coordinate an immune response. Around 85 percent of babies (116 million) received three

Hypoxia is a situation in which the blood and bodily tissues do not receive adequate oxygen. Hypoxia can be generalised, affecting the entire body, or localised, affecting a specific bodily part. The normal arterial oxygen level of 80 is 75 to 100 millimetres of mercury (mm Hg), and normal pulse oximeter values are 95 to

Proteins are required for the structural integrity and function of all living organisms. Protein accounts for nearly half of the total dry weight of a cellular structure. A protein is an organic compound with many molecules. It is made up of amino acids linked together by peptide bonds. Proteins are composed of 20 amino acids;

Microbiology is the study of unicellular or cell-cluster tiny creatures known as microbes. Microorganisms are microscopic living organisms that are too small to be seen with the naked eye. Microorganisms are organisms with a diameter of less than 1 mm and belong to the field of microbiology. Because most microbes are only a few thousandths

Female foeticide in India has been a very common practice since the early 1990s. To stop this, govt. India introduced the Preconception & Prenatal Diagnostic Techniques Act in 1994. This act aimed at controlling the declining ratio of females to males. To achieve this the government decided to stop prenatal diagnosis. This act was amended

Primates are an order of mammals. Animals in this category have prehensile hands and feet, i.e., hands and feet that can easily grasp objects. Opposable thumbs are also common amongst primates. Common primates include gorillas, chimpanzees, lemurs, monkeys, and humans.  What are Primates? ‘Primate’ is a term used to describe a specific group of mammals.
