Demand-responsive bus service of the Oxford Bus Company in 2018. Demand-responsive transport (DRT), also known as demand-responsive transit, demand-responsive service, [1] Dial-a-Ride [2] transit (sometimes DART), [3] flexible transport services, [4] Microtransit, [5] Non-Emergency Medical Transport (NEMT), [5] Carpool [6] or On-demand bus service is a form of shared private or quasi-public ...
There are two types of active transport, primary active transport and secondary active transport. [citation needed] Primary active transport uses adenosine triphosphate (ATP) to move specific molecules and solutes against its concentration gradient. Examples of molecules that follow this process are potassium K +, sodium Na +, and calcium Ca 2+.
Demand responsive transport, a form of public bus service; Downtown Relief Line, a proposed subway line in Toronto, Canada; Durham Region Transit, a Canadian public transit operator; Digital-rail Rapid Transit, a type of Autonomous Rail Rapid Transit
They all share the same structure for the first 7 fields, while differing in the content and format of the ninth field. Some field names have been changed in GFF3 to avoid confusion. For example, the "seqid" field was formerly referred to as "sequence", which may be confused with a nucleotide or amino acid chain. The general structure is as ...
An example of an antiporter mediated transport protein is the sodium-calcium antiporter, a transport protein involved in keeping the cytoplasmic concentration of calcium ions in the cells, low. This transport protein is an antiporter system because it transports three sodium ions across the plasma membrane in exchange for a calcium ion, which ...
The extensible NEXUS file format is widely used in bioinformatics.It stores information about taxa, morphological and molecular characters, distances, genetic codes, assumptions, sets, trees, etc. [1] Several popular phylogenetic programs such as PAUP*, [2] MrBayes, [3] Mesquite, [4] MacClade [5] and SplitsTree [6] use this format.
A Rhode Island man has admitted to using gasoline to set several fires around the exterior of a predominantly Black church earlier this year, according to a federal plea agreement.
Facilitated diffusion in cell membrane, showing ion channels and carrier proteins. Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
