Motile marine animals are commonly called free-swimming, [10] [11] [12] and motile non-parasitic organisms are called free-living. [13] Motility includes an organism's ability to move food through its digestive tract. There are two types of intestinal motility – peristalsis and segmentation. [14]
After an introductory chapter, the remaining 15 chapters are divided into four major parts. The book's first part focuses on the faith/health relation in the general population. Chapter 2 by Carl E. Thoresen and his colleagues describes the existing empirical evidence, and discusses many methodological issues. The authors view the evidence as ...
Swarming motility is a rapid (2–10 μm/s) and coordinated translocation of a bacterial population across solid or semi-solid surfaces, [61] and is an example of bacterial multicellularity and swarm behaviour. Swarming motility was first reported in 1972 by Jorgen Henrichsen.
Life table" primarily refers to period life tables, as cohort life tables can only be constructed using data up to the current point, and distant projections for future mortality. Life tables can be constructed using projections of future mortality rates, but more often they are a snapshot of age-specific mortality rates in the recent past, and ...
Sperm motility is dependent on several metabolic pathways and regulatory mechanisms. The axonemal bend movement is based on the active sliding of axonemal doublet microtubules by the molecular motor dynein, which is divided into an outer and an inner arm. Outer and inner arm plays different roles in the production and regulation of flagellar motility: the outer arm increase the bea
For her last two flocks, Kemp bought nine chicks for $10 from a farmer who lives an hour away. Kristin Bell, who has been raising backyard chickens for 15 years, says the eggs they yield taste ...
Twitching motility is a form of crawling bacterial motility used to move over surfaces. Twitching is mediated by the activity of hair-like filaments called type IV pili which extend from the cell's exterior, bind to surrounding solid substrates, and retract, pulling the cell forwards in a manner similar to the action of a grappling hook.
For both of the quotes, de Moivre's references to "tables" were to actuarial life tables. Modern authors are not consistent in their treatment of de Moivre's role in the history of mortality laws. On the one hand, Dick London describes de Moivre's law as "the first continuous probability distribution to be suggested" for use as a model of human ...
