Some motile cilia lack the central pair, and some non-motile cilia have the central pair, hence the four types. [5] [7] Most non-motile cilia, termed primary cilia or sensory cilia, serve solely as sensory organelles. [8] [9] Most vertebrate cell types possess a single non-motile primary cilium, which functions as a cellular antenna.
The International Boundary and Water Commission (IBWC, Spanish: Comisión Internacional de Límites y Aguas, CILA) is an international body created by the United States and Mexico in 1889 to apply the rules for determining the location of their international boundary when meandering rivers transferred tracts of land from one bank to the other, as established under the Convention of November 12 ...
The Central Intelligence Agency (CIA / ˌ s iː. aɪ ˈ eɪ /), known informally as the Agency, [6] metonymously as Langley [7] and historically as the Company, [8] is a civilian foreign intelligence service of the federal government of the United States tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human ...
Cilia occur in all members of the group (although the peculiar Suctoria only have them for part of their life cycle) and are variously used in swimming, crawling, attachment, feeding, and sensation. Ciliates are an important group of protists , common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils, including anoxic ...
Paramecium caudatum [1] is a species of unicellular protist in the phylum Ciliophora. [2] They can reach 0.33 mm in length and are covered with minute hair-like organelles called cilia. [3]
The cilia have a length of up to 100 micrometres and with the cilia from other dendrites form a meshwork in the olfactory mucus. [5] The surface of the cilia is covered with olfactory receptors , a type of G protein-coupled receptor .
While the broad strokes of Social Security have been in place since 1934, the program is ever-evolving. In fact, some changes, such as the cost-of-living adjustment, are made every year, while ...
A study based on splicing morpholinos to down-regulate MsrB3 expression in zebrafish showed shorter, thinner, and more crowded cilia, as well as small, misplaced otoliths. Several stereocilia also underwent apoptosis. Injection with wild-type MsrB3 mRNA rescued auditory deficits, suggesting MsrB3 helps prevent apoptosis. [15]
