Absorption vs Adsorption: Definitions and Examples The process of absorbing something involves allowing it to diffuse or osmotically permeate tissues or onto a surface like a cell. The fluid (absorbate) permeates the entire absorbent material in this bulk phenomenon. Endothermic absorption needs energy to take in the particles. Adsorption is the process by which molecules, […]
A solution with a lower solute concentration than the cell is called a hypotonic solution. Combinations of a solute and a solvent are called solutions. Substances that are present in smaller amounts are known as solutes, whereas substances that are present in larger amounts are known as solvents. Salt water is one example of a
A chemical test called the Acree-Rosenheim reaction is performed to find out if proteins contain tryptophan. Formaldehyde is combined with a protein combination. To create two layers, add concentrated sulfuric acid. If the test results for tryptophan are positive, a purple ring will show up between the two layers. Acree-Rosenheim Test definition A scientific technique
Ideonella sakaiensis A group of Japanese scientists from Keio University and the Kyoto Institute of Technology discovered the bacteria in 2016. It was shown to have the unusual capacity to break down and integrate polyethylene terephthalate (PET), a typical plastic used in bottles and packaging, at a plastic recycling plant in Sakai, Japan. Introduction of

Active transport is the process by which chemicals are transferred from a region of lower concentration to a region of greater concentration across a cell membrane against the gradient of their concentration. Since this process is operating against the direction that diffusion naturally takes, energy, often in the form of adenosine triphosphate (ATP), is required.
In molecular biology, agarose gel electrophoresis is a frequently employed method for size-based protein, DNA, and RNA separation. Using the characteristics of agarose, a polysaccharide that is isolated from seaweed, this technique creates a gel matrix that allows proteins or nucleic acids to move across it in response to an electric field. This is a

Aerobic Respiration Aerobic respiration is a metabolic process that takes place in the presence of oxygen and involves the breakdown of organic molecules, mainly glucose, to release energy in the form of ATP (adenosine triphosphate), CO2, and water. Most eukaryotic species rely on this very efficient mechanism for energy generation. Example: Human Cells (such as

Domains of Life : Bacteria Bacteria are microscopic, one-celled organisms. Bacteria come in millions of different varieties. Numerous substances that are good for you can be found in and on your body. Your microbiome, which is made up of these bacteria, maintains the health of your body. You can become ill from other bacteria. Antibiotics
Organisms are living being with an ordered structure that can respond to stimuli, reproduce, develop, adapt, and maintain homeostasis. They may be found in a variety of habitats and serve an important part in preserving the natural equilibrium. Each creature has distinct traits and adaptations that enable it survive and thrive in its specialized environment.
Acinetobacter baumannii Humans can become seriously infected with the Gram-negative bacterium Acinetobacter baumannii. Often affecting individuals with weakened immune systems, this opportunistic infection bears the name Paul Baumann after the bacteriologist who discovered it. Particularly in nosocomial settings, the significance of this bacteria as a hospital-derived infection is growing. It can result in wounds in
