The Atomic Absorption Spectrophotometer (AAS) is referred to as an analytical instrument that measures the absorption of specific Light wavelength’s by free atom’s, which is required for determining metal concentration in a sample. It is considered a method where atoms in the Ground State absorbs radiation, leading to characteristic signals that are recorded by the … Read more
What is Color Spectrophotometer? A color spectrophotometer is referred to as an optical instrument that is utilized for measuring the intensity of light at various wavelength’s, which gives a look into how a sample’s surface reflect or absorb color’s in a quite systematic way. It is considered a device that records the reflectance spectrum, which … Read more
What are Microscopes? A microscope can define as an optical or electronic Instrument that is used for observing objects’ that are too small for the naked eye, and it gives a look into structures in biology/physics etc. In general terms, the device is characterized by lenses, illumination sources, and also by Magnification system’s that allow … Read more
A centrifuge can define as a laboratory device that use rapid rotational Force to separate component’s of a mixture based on their Density difference’s, and it is considered a key Instrumentation in many biological / chemical workflows. What is Relative Centrifugal Force (RCF)? Relative Centrifugal Force (RCF) is the effective acceleration a particle experiences in … Read more

Biopiracy, Intellectual Property Rights and Traditional Knowledge. Ethnobotany is the branch of science which deals with the study of how different plants are used by indigenous people for their … Read more
What Is Trochophore Larva? Trochophore larva refers as an early free-swimming stage found by many marine invertebrates like annelids, mollusks, etc. It can define as – a small, spherical or pear-shape larva having a ring of cilia (called prototroch) around its middle part. This larva usually formed after fertilization → from the zygote → and … Read more
Pureline selection is a method used in plant breeding where plants are chosen from a single self-pollinated variety to create a population that is genetically uniform. It was first introduced by Johannsen (1903) while working with beans (Phaseolus vulgaris). The method based on assumption that variation seen in self-pollinated crops is mostly due to environment … Read more
What is Budding? Definition of Budding Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or “bud” on the parent organism, eventually detaching to live independently. Types of Budding I. Types of Biological Budding (Asexual Reproduction) II. Types of Horticultural Budding (Plant Grafting Techniques) 1. Budding in Plants … Read more
What is Nondisjunction? Types of Nondisjunction Causes of Nondisjunction Molecular Biology of Nondisjunction Consequences of Nondisjunction The nondisjunction is the failure when chromosomes don’t separate properly during cell division (like meiosis/mitosis), causing abnormal number of chromosomes in daughter cells. Such imbalance is termed as aneuploidy, sometimes loss of one (monosomy 2n–1) or gain of one … Read more
Membrane Filter Technique can define as a physical separation process, which based mainly on size / molecular weight of particles in a liquid or gas stream. In this method a thin semi-permeable membrane (often made from cellulose nitrate/acetate) is used, and pressure is applied to push the feed solution by it. The smaller components pass … Read more
