"Rhoptries" Natural Recordings by Native Speakers
The words "rhoptries" refers to a structure found in certain unicellular parasites, such as Toxoplasma gondii. Rhoptries are organelles that are involved in the invasion of host cells.
In more detail, rhoptries are paired, secretory organelles of the sporozoan parasites, such as Plasmodium spp. and Toxoplasma gondii. They are involved in the parasitoid invasion of host cells and the formation of parasitophorous vacuoles.
The term "rhoptries" is derived from the Greek word "rhopos" which means "blunt" or "bodied". Rhoptries are typically club-shaped and are one of the most distinctive features of the parasitoid's cells.
In Toxoplasma gondii, rhoptry secretion proteins interact with the host's cell membrane to facilitate the parasite's invasion of the cell, while also providing the necessary energy to accomplish this.
The Rhône is a major river in eastern France and Switzerland, about 812 kilometers long and it drains most of central-eastern France. <br><br>It is a significant waterway in the southeastern region of France, where it flows through the city of Lyon. The river originates in Switzerland, where it is called the Rhin, joining the River Aare to form the Reuss.<br><br>The Rhône is joined by the Saône River in Lyon. The joining rivers form a unique opposing currents phenomenon that is known as the "Saône Seine tidal conveyor belt."<br><br>From Lyon, the Rhône flows northwards, along with the waterway connected to the Mediterranean and flows to the sea.
Rhopalic is a rhetorical device used in speech or writing, where a phrase is repeated by using synonyms, often in a series of words. It is also known as "reduplication." The word "rhopalism" although not widely used, describes a rhopalism in poetry or rhythm, specifically a short succession of identical words.<br><br>Examples of how it is used include repeating a word many times with slight modifications, for example: "free, frank, frank, frankness, franker", rather than using identical words in repetitive pattern like: "free, free, free".
The term "rhotic" refers to a type of accent or dialect in which the sound /r/ is pronounced after a vowel. This is in contrast to non-rhotic accents, where the /r/ is often silent after a vowel.<br><br>In rhotic accents, the /r/ is often pronounced as a distinct sound, especially in words like "car," "bar", and "far". This means that the /r/ is pronounced with a clear and typical "r" sound.<br><br>Examples of rhotic accents include many North American dialects, such as General American, some Scottish and Irish dialects, and some Caribbean dialects.<br><br>In contrast, non-rhotic accents, such as Received Pronunciation (RP) or Cockney, often do not pronounce the /r/ sound after a vowel, so instead of "car", it sounds like "cah".<br><br>Rhoticity is an important feature of some English accents and can affect how words are pronounced and spoken.
Rhoticization refers to the process by which non-rhotic languages or dialects, characterized by the absence or near-absence of the sound /r/ in certain positions, evolve to incorporate this sound in their pronunciation. This can occur through contact with languages that have a presence of /r/, such as in the process of language convergence or borrowing.<br><br>For example, in the past, Received Pronunciation (RP) in England did not have a distinct pronunciation of the sound /r/. The historical pronunciation had a different set of features, and it was often phonetically and phonologically realized as a non-r or /r/ was absent altogether. However, the influence of immigrant languages such as Scottish and Irish has led to certain forms of RP exhibiting rhoticity under certain syllable conditions, similar to those found in American English.<br><br>Rhoticization can also be seen in non-standard dialects.
