    Coordinating conjunctions, also called coordinators, are conjunctions that join, or coordinate, two or more items (such as words, main clauses, or sentences) of equal syntactic importance. In English, the mnemonic acronym FANBOYS can be used to remember the most commonly used coordinators : for , and , nor , but , or , yet , and so . [ 13 ]

    Complementation tests can also be carried out with haploid eukaryotes such as fungi, with bacteria, and with viruses such as bacteriophage. [1] Research on the fungus Neurospora crassa led to the development of the one-gene-one-enzyme concept that provided the foundation for the subsequent development of molecular genetics.

    Biological organization spans several scales and are determined based different structures depending on what the system is. [1] Examples of biological systems at the macro scale are populations of organisms. On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the ...

    In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function.

  9. Tight junction - Wikipedia

    en.wikipedia.org/wiki/Tight_junction

    Zonula Occludin 1 (ZO-1) serves as the scaffolding protein for the tight junction. This means that it directly links the tight junction proteins to the f-actin cytoskeleton. In addition to anchoring claudins, occludin, and JAMs to the apical region of the cell membrane, ZO-1 has also been implicated in important cellular processes such as ...
