Muscular tissue is a type of tissue present in the group metazoans, for the body movement or locomotion. Metazoans are the multicellular organisms belongs to the kingdom Animalia, whose cells differentiates to form tissues and organ. Muscular tissue provides mobility to the body organs of the organism. Muscle tissues are of three types namely striated, unstriated …
Ozone depletion is the process of destruction of the ozone layer in the stratospheric region. It can adversely affect various living forms. Ozone depletes by the many pollutants that are emitting out from the vehicles, industries etc. Ozone layer depletion is one of the major environmental issues, which needs to be controlled as the layer …
A Bacteriophage possesses viral proteins, which can disrupt their host cell, i.e. Bacteria. It first attaches to the susceptible bacterial cell and injects its genetic material into the host cell. The viral genome within the host cell takes over the cell machinery and uses the bacterial components to release viral proteins. Eventually, the viral proteins …
The rhizosphere is a term, which was first introduced by a scientist L.Hiltner. It is the region that is a few distances (2-80mm) extended from the root system. It can also define as a zone, which favours the physical and chemical activity of the microorganisms and responsible for the intense microbial activity. The rate of …
The difference between passive and active transport is mainly due to the two properties, like the movement of particles and the use of ATP. The movement of particles: It occurs from a high to a low concentration in passive diffusion, whereas the particles move from a low to a high concentration in active transport. Use …
Definition: Immobilization can define as the enticement of an enzyme to a solid support. Enzyme immobilization is a process, which encloses the enzyme molecules to an absolute phase from a bulk phase. The bulk phase consists of substrates, effectors and inhibitors. Enzyme molecule impounds in or on some suitable matrix that is having a definite …
Definition: Cyanobacteria represents the major group of photosynthetic bacteria, which can carry out the oxygenic photosynthesis. It releases oxygen and uses water as an electron-donating substrate, i.e. splits water molecule to release oxygen. Other than this, they are also capable of fixing nitrogen. Classification of Cyanobacteria Kingdom: Monera Division: Eubacteria Class: Cyanobacteria Examples: Nostoc sp., …
Definition: Any undesirable change or deterioration in the quality of milk is called Spoilage of milk. These changes can be like an unpleasant appearance, colour, odour, taste etc. Milk contains a complex biochemical composition and a high water activity, due to which it provides an excellent culture medium for the growth and multiplication of microorganisms …
The difference between antigen and antibody is mainly due to the following factors like functional role, specificity factor and foreignness. Functional role: Antigen incites the immune system, whereas the antibody is produced in response to a specific antigen. Specificity factor: Both antigen and antibody are specific. The specificity of antigen is due to the presence …
Definition: Staining is a method of imparting colour to cells, tissues or microscopic components, so they are highlighted and visualized better under a microscope. There are a variety of staining methods like simple, differential and special staining, which are used for various purposes ranging from the study of microscopic organisms to cellular structures, metabolic processes, …
