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.
The immune system’s anatomical barriers serve as the initial line of protection against infections. These chemical and physical barriers stop dangerous bacteria from entering the body. The skin and mucous membranes are two of these barriers that are most important. Being the biggest organ in the body, the skin acts as a strong defense against […]

Active immunity is a type of adaptive immunity in which the immune system produces antibodies and memory cells after being exposed to a disease-causing pathogen. This process can happen spontaneously when a person contracts a pathogen, or it can be induced intentionally by vaccination. It is characterized by the involvement of the immune system, which

What is Agglutination? Agglutination is a biological phenomena that occurs when particular antibodies or antigens cause particles, such cells or bacteria, to cluster together. Antibodies attach to antigens on the surface of particles, causing visible aggregates or clumps to develop. This is the reaction that happens. Agglutination assays are widely used in biology, medicine, and

Agglutination vs precipitation are both immunological reactions that occur when antigens and antibodies interact, but agglutination vs precipitation differ in terms of their procedures, results, and uses. Here is a thorough comparison: Definitions: Agglutination Clumping of particles is known as agglutination. This process happens when particulate antigens, including cells or insoluble particles, attach to antibodies

Albert Staining is a special staining technique used primarily for the visualization of metachromatic granules (also known as volutin or Babes-Ernst granules) within bacterial cells, particularly in Corynebacterium diphtheriae. These granules are composed of polymetaphosphate and are characteristic of certain bacteria. Over time, certain stains have been created to help with species identification, morphological differentiation,

Polymerase Chain Reaction is a technique used in molecular biology to create several copies of a certain DNA segment. The PCR technique, created in 1983 by Kary Mullis, facilitates the study and analysis of genetic material by enabling researchers to produce millions of copies of a certain DNA sequence from a tiny original sample. Types

Within the range of human health situations are two separate categories: Acute disease vs Chronic disease . Acute illnesses are defined by their abrupt onset and frequently severe symptoms that appear quickly. Most of these illnesses have a short course and clear up rather quickly. On the other hand, chronic illnesses endure for a long

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.
