Artificial Selection- Definition, Steps, Examples, Uses

What is Artificial Selection? Artificial Selection is the deliberate breeding of plants or animals with desired features to generate offspring with those same traits is called artificial selection, or selective breeding. Many domesticated species, including crops, animals, and pets, have been developed as a result of this process, which dates back thousands of years. Steps […]

Antigens: A Comprehensive Guide for Beginners

Biology / Upshan

What is Antigens? Antigens is anything that can cause the body to mount an immunological response is considered an antigen. These materials may consist of nucleic acids, lipids, proteins, or polysaccharides. The immune system views antigens as foreign or non-self substances, and in reaction, they either trigger the creation of antibodies or activate immune cells

Analogous Structures: Definition, 4 Examples, Significances

Biology / Upshan

What is Analogous Structures ? As opposed to homologous structures, which originate from a common ancestral feature, analogue features are characteristics of distinct species that have developed in response to comparable environmental challenges and are similar in function but not always in structure. Comparable biological structures are those seen in various species that serve comparable

Alpha Oxidation: Location, Pathway, Steps, Significance

Biology / Upshan

What is Alpha Oxidation? A metabolic process mainly takes place in the liver and kidneys and involves the breakdown of branched-chain fatty acids, especially those that have a methyl group joined to the carbon atom close to the carboxyl group. This is not the same as beta oxidation, which is the main process that breaks

Agglutination: Reactions, Types, Tests, Applications

Biology / Upshan

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

Acute disease vs Chronic disease- Definition, 13 Differences, Examples

Biology / Upshan

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
