Chronobiology – field of biology that examines periodic (cyclic) phenomena in living organisms and their adaptation to solar- and lunar-related rhythms. Dendrochronology – study of tree rings, using them to date the exact year they were formed in order to analyze atmospheric conditions during different periods in natural history.
The News Quiz was created by John Lloyd, [2] based on an idea by Nicholas Parsons. [3]The series was first broadcast in 1977 with Barry Norman in the chair. Subsequently it was chaired by Barry Took from 1979 to 1981, Simon Hoggart from 1981 to 1986, Took again from 1986 to 1995, and then again by Hoggart from 1996 until March 2006. [4]
The math test is weighted more heavily, with 35 questions worth approximately 28.6 points per question. Until 2013, the Super Quiz written test contained 40 questions, each worth 15 points. Depending on the state director, the relay component of Super Quiz contained either 5 or 10 questions, each worth 80 or 40 points respectively.
Biologists can study life at multiple levels of organization, [1] from the molecular biology of a cell to the anatomy and physiology of plants and animals, and the evolution of populations. [ 1 ] [ 6 ] Hence, there are multiple subdisciplines within biology , each defined by the nature of their research questions and the tools that they use.
The dose–response relationship, or exposure–response relationship, describes the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time. [1] Dose–response relationships can be described by dose–response curves. This is explained further ...
This six-kingdom model is commonly used in recent US high school biology textbooks, but has received criticism for compromising the current scientific consensus. [13] But the division of prokaryotes into two kingdoms remains in use with the recent seven kingdoms scheme of Thomas Cavalier-Smith, although it primarily differs in that Protista is ...
A combination of topical and systematic antibiotics taken prophylactically can prevent infection and improve adults' overall mortality in the ICU for adult patients receiving mechanical ventilation for at least 48 hours, and topical antibiotic prophylaxis probably reduces respiratory infections but not mortality.

Round Britain Quiz (RBQ) is a panel game that has been broadcast on BBC Radio since 1947, making it the oldest quiz still broadcast on British radio. It was based on a format called Transatlantic Quiz , a contest between American and British teams on which Alistair Cooke was an early participant.
