Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.
Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.
Alleles are an essential part of genetics that are necessary to understand inheritance patterns and genetic diversity.Both gene variations are unique and share a chromosomal locus (position). An individual inherits one variant of the gene from each parent. The presence of distinct gene variants can result in variations of the same characteristic or different traits. […]

Vaccination, or active immunization, is the process of stimulating an individual’s immune system to establish immunity against a particular illness or virus. The infection or its toxins are introduced into the body in a form that is weakened, destroyed, or fragmented in order to accomplish this. Upon identifying these foreign materials as antigens, the immune
The Acid Fast Stain is a scientific method for identifying acid-fast microorganisms such as Mycobacterium tuberculosis. The theory behind this stain is based on particular bacteria’s capacity to maintain a red dye known as carbol fuchsin even after being treated to an acid-alcohol decolorizer. What is Acid Fast Stain? The Acid Fast Stain, commonly known

Centrifugation Centrifugation is a technique used in laboratories and various industries to separate components of a mixture based on their density, size, viscosity, and shape. Newton’s first law of motion, which states that an object remains at rest or in uniform motion until forced upon by an external force, is the fundamental tenet of its.
There are two main categories of animals: vertebrates and invertebrates, each having unique traits. Examine the variations among these groupings, taking into account their responsibilities in the environment, reproductive techniques, and physical characteristics. Discover the wide range of species that make up each group and how they add to the ecosystems’ diversity on Earth.” Various

A solution with a lower solute concentration than the cell is called a hypotonic solution. Combinations of a solute and a solvent are called solutions. Substances that are present in smaller amounts are known as solutes, whereas substances that are present in larger amounts are known as solvents. Salt water is one example of a
A chemical test called the Acree-Rosenheim reaction is performed to find out if proteins contain tryptophan. Formaldehyde is combined with a protein combination. To create two layers, add concentrated sulfuric acid. If the test results for tryptophan are positive, a purple ring will show up between the two layers. Acree-Rosenheim Test definition A scientific technique
Ideonella sakaiensis A group of Japanese scientists from Keio University and the Kyoto Institute of Technology discovered the bacteria in 2016. It was shown to have the unusual capacity to break down and integrate polyethylene terephthalate (PET), a typical plastic used in bottles and packaging, at a plastic recycling plant in Sakai, Japan. Introduction of

Active transport is the process by which chemicals are transferred from a region of lower concentration to a region of greater concentration across a cell membrane against the gradient of their concentration. Since this process is operating against the direction that diffusion naturally takes, energy, often in the form of adenosine triphosphate (ATP), is required.
In molecular biology, agarose gel electrophoresis is a frequently employed method for size-based protein, DNA, and RNA separation. Using the characteristics of agarose, a polysaccharide that is isolated from seaweed, this technique creates a gel matrix that allows proteins or nucleic acids to move across it in response to an electric field. This is a
