Streptomycin is an aminoglycoside antibiotic with a broad spectrum of activity against Gram-negative and Gram-positive bacteria. The antibiotic is synthesized by soil-dwelling aerobic bacteria of the genus Streptomyces, which form a large family and belong to the actinobacteria. Because of its undesirable side effects and risk of developing resistance, streptomycin is mainly used to combat … Streptomycin: Effects, Uses & Risks
Red cell osmotic resistance is a measure of how strongly the membranes surrounding red cells resist an osmotic pressure gradient. A partial osmotic pressure develops at the semipermeable membranes of erythrocytes when they are surrounded by a saline solution that is below their own (physiological) salt concentration of 0.9 percent. Red blood cells absorb water … Erythrocyte Osmotic Resistance: Function, Role & Diseases
The entire cell cycle is controlled by a checkpoint system. A cell cycle checkpoint regulates critical processes and phase transitions that occur within a cell cycle. What is the cell cycle checkpoint? The entire cell cycle is controlled by a control system. A cell cycle checkpoint regulates critical processes and phase transitions that occur within … Cell Cycle Checkpoint: Function, Tasks, Role & Diseases
Furrowing of the zygote is a cell division in early embryogenesis. It follows fertilization and is part of preembyonic development. Errors in furrow division are associated with gene mutations such as trisomies or parental disomies. What is furrowing? Furchung of the zygote is a cell division in early embryogenesis. It follows fertilization and is part … Furrow: Function, Tasks, Role & Diseases
In membrane transport, substances pass through a biological membrane or are actively transported through membranes. Unlike active transport, diffusion is the simplest membrane transport pathway and requires no additional provision of energy. Disorders of membrane transport are associated with a variety of different diseases. What is membrane transport? Membrane transport is when substances pass through … Membrane Transport: Function, Role & Diseases
