Biology

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.

Phenotypic Characteristics and Phenotypic Changes

Phenotypic Characteristics and Phenotypic Changes

Biology /

The observable characteristics of an organism that arise from the interplay between its environment and genetic composition (genotype) are referred to as phenotypic characteristics. These characteristics may be behavioral (reactions to stimuli), physiological (metabolism, growth rate), or morphological (size, shape, and color). Environmental influences and genetic factors can both affect phenotypic traits, which are the […]

Mutagenesis and Mutagens

Mutagenesis and Mutagens

Biology /

Mutagenesis is the process via which an organism’s genetic material is changed, leading to a mutation. This can be created purposefully with chemical, physical, or biological agents, or it might happen naturally as a result of mistakes in DNA replication. In order to comprehend gene function, generate genetic diversity, and enhance an organism’s features, mutagenesis

Adrenal gland: structure, location and hormones

Biology /

The adrenal glands are significant endocrine glands that generate a range of hormones essential for controlling blood pressure, metabolism, immunological response, and stress reactions. An outline of their composition, location, and hormones secreted is shown below. Adrenal gland: structure, location and hormones Location The endocrine system of the body includes the glands, which are situated

Parathyroid Gland

Parathyroid Gland

Biology /

On the back of the thyroid gland are tiny endocrine glands called parathyroid glands. Notwithstanding their diminutive size, these glands are essential for controlling calcium levels, which are necessary for bone health, muscle contraction, and nerve function. The four tiny, pea-shaped glands in the neck that make parathyroid hormone (PTH) are called parathyroid glands. The

Ames test -a test for Mutagenicity; Principle, Procedure and Application

Biology /

A biological test called the Ames test is used to evaluate a chemical compound’s capacity to cause mutagenesis. In particular, it uses bacteria as the test system to determine whether a drug can alter the DNA of living things. Principle The foundation of the Ames test is the idea that certain strains of Salmonella typhimurium

Muscle-Skeletal Muscle-Gross and Ultra Structure

Biology /

Different degrees of research and study of the body’s muscles are referred to by the names Muscle-skeletal Muscle-gross and Ultrastructure. An explanation of each is provided below: Muscle-Skeletal System The human body’s structure, support, and mobility are provided by the intricate network of bones, joints, muscles, tendons, and ligaments that make up the musculoskeletal system.
