Sep 1, 2024 · When the electricity is applied, molecules migrate towards their isoelectric pH. The mobility of sample molecules stops at their respective isoelectric pH, where the net charge on the sample molecule is zero. IEF can provide excellent resolution and fractionation of serum proteins and hemoglobin variants.
Sep 9, 2024 · Homeostasis, any self-regulating process by which biological systems tend to maintain stability. The stability attained represents a dynamic equilibrium, in which continuous change occurs yet relatively uniform conditions prevail. If homeostasis is successful, life continues; if unsuccessful, disaster or death ensues.

4 days ago · Biology is the scientific study of life. [1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [1][2][3] For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
Sep 19, 2024 · scanning electron microscope (SEM), type of electron microscope, designed for directly studying the surfaces of solid objects, that utilizes a beam of focused electrons of relatively low energy as an electron probe that is scanned in a regular manner over the specimen.

Sep 20, 2024 · Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.
