Catalase - an overview | ScienceDirect Topics- define detergent in biology chart ,It is necessary to use a detergent (e.g. 1 % Triton-X-100) in the preparation of the stock homogenate (1:10 or 1:20). Further dilutions can be made with phosphate buffer, pH 7.0 (1:100 to 1:500 according to the tissue and the species). The catalase activity of tissue samples is normally expressed on a mg. wet weight or mg. total-N basis.Fractionation of Cells - Molecular Biology of the Cell ...Although biochemical analysis requires disruption of the anatomy of the cell, gentle fractionation techniques have been devised to separate the various cell components while preserving their individual functions. Just as a tissue can be separated into its living constituent cell types, so the cell can be separated into its functioning organelles and macromolecules.

Detergents: Triton X-100, Tween-20, and More
Aug 02, 2021·The headgroups of zwitterionic detergents are hydrophilic and contain both positive and negative charges in equal numbers, resulting in zero net charge. They are more harsh surfactants than the non-ionic detergents. A typical zwitterionic detergent is 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate, better known as CHAPS.

Biodegradation - Wikipedia
Mechanisms. The process of biodegradation can be divided into three stages: biodeterioration, biofragmentation, and assimilation. Biodeterioration is sometimes described as a surface-level degradation that modifies the mechanical, physical and chemical properties of the material.

A taxonomy chart is the organized graphic practice and representation of things and concepts. Usually, the taxonomy chart is used in biology to classify all living things. In the 18th century, Carolus Linnaeus suggested a classification process, and this taxonomy system is still used today. In a chart, taxonomy is an abstract rank or level.

Hardness of Water - USGS
Water systems using groundwater as a source are concerned with water hardness, since as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply.Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around a water-supply well, hard water may be delivered to homes.
