Cation vs Anion: Definition, Chart and the Periodic Table
WEBAug 15, 2019 · Cation vs anion periodic table. It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form ...
DNA vs. RNA – 5 Key Differences and Comparison
WEBDec 18, 2020 · DNA is a much longer polymer than RNA. A chromosome, for example, is a single, long DNA molecule, which would be several centimetres in length when unraveled. RNA molecules are variable in length, but much shorter than long DNA polymers. A large RNA molecule might only be a few thousand base pairs long. Sugar.
Essential Amino Acids: Chart, Abbreviations and Structure
WEBSep 26, 2019 · What is the structure of the amino acids? An amino acid’s structure consists of a central carbon atom attached to a hydrogen, an acidic carboxyl group (−COOH), an amino group (−NH2) and an organic side chain (also called an R group). The side chain is unique in each of the 20 amino acids. Amino acid. Abbreviation.
Active vs Passive Immunity: Differences and Definition
WEBMay 20, 2020 · Active immunity is defined as immunity to a pathogen that occurs following exposure to all or part of that pathogen. When the body is exposed to a novel disease agent, a cascade of signaling molecules and action from the innate immune system results in activation of the adaptive immune system.

Prokaryotes vs Eukaryotes: What Are the Key Differences?
WEBJul 8, 2021 · The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
Gray Matter vs White Matter - Technology Networks
WEBAug 20, 2019 · Gray matter is made up of neuronal cell bodies, while white matter primarily consists of myelinated axons. In the brain, white matter is found closer to the center of the brain, whereas the outer cortex is mainly grey matter. The reverse is true in the spinal cord, which has a grey matter-lined interior with white matter on the outside.
GC-MS Principle, Instrument and Analyses and GC-MS/MS
WEBJun 10, 2022 · The sample mixture is first separated by the GC before the analyte molecules are eluted into the MS for detection. 1 They are transported by the carrier gas (Figure 1 (1)), which continuously flows through the GC and into the MS, where it is evacuated by the vacuum system (6). 1. The sample is first introduced into the GC …
