John Randal Baker FRS (23 October 1900 – 8 June 1984) was an English biologist, zoologist, and microscopist, and a professor at the University of Oxford, where he was Emeritus Reader in Cytology. He received his D.Phil. at the University of Oxford in 1927. Early life Baker was the youngest of five children born to Rear Admiral Julian Alleyne Baker and his wife Geraldine Eugenie (née Alison). He was a grandson of General Sir Archibald Alison and among the papers collected in Baker's name at the Bodleian Library are volumes of correspondence and other material related to Alison's military service during the Indian Mutiny, Ashanti Campaign, and Egyptian Campaign of 1882. Born in Woodbridge, Baker grew up in a country home near Bromyard. At age ten, he was sent to Boxgrove School, near Guildford.

Seasonal Breeder
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species. Related sexual interest and behaviors are expressed and accepted only during this period. Female seasonal breeders will have one or more estrus cycles only when she is "in season" or fertile and receptive to mating. At other times of the year, they will be anestrus, or have a dearth of their sexual cycle. Unlike reproductive cyclicity, seasonality is described in both males and females. Male seasonal breeders may exhibit changes in testosterone levels, testes weight, and fertility depending on the time of year. Seasonal breeders are distinct from opportunistic breeders, that mate whenever the conditions of their environment become favorable, and continuous breeders that mate year-rou ...

Vanuatu
Vanuatu ( or ; ), officially the Republic of Vanuatu (; ), is an island country in Melanesia located in the South Pacific Ocean.

Spermatogenesis
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testicle. This process starts with the Mitosis, mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called Spermatogonial Stem Cells, spermatogonial stem cells. The mitotic division of these produces two types of cells. Type A cells replenish the stem cells, and type B cells differentiate into primary spermatocytes. The primary spermatocyte divides meiotically (Meiosis I) into two secondary spermatocytes; each secondary spermatocyte divides into two equal haploid spermatids by Meiosis II. The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis. These develop into mature spermatozoa, also known as sperm, sperm cells. Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatoz ...

British Undergraduate Degree Classification
The British undergraduate degree classification system is a Grading in education, grading structure used for undergraduate degrees or bachelor's degrees and Master's degree#Integrated Masters Degree, integrated master's degrees in the United Kingdom. The system has been applied, sometimes with significant variation, in other countries and regions. The UK's university degree classification system, established in 1918, serves to recognize academic achievement beyond examination performance. Bachelor's degrees in the UK can either be honours or ordinary degrees, with honours degrees classified into First Class, Upper Second Class (2:1), Lower Second Class (2:2), and Third Class based on weighted averages of marks. The specific thresholds for these classifications can vary by institution. Integrated master's degrees follow a similar classification, and there is some room for discretion in awarding final classifications based on a student's overall performance and work quality.

It differs from paddling sports in that rowing oars (called blades in the United Kingdom) are attached to the boat using Rowlock, rowlocks, while paddles are not connected to the boat. Rowing is divided into two disciplines: sculling and sweep rowing. In sculling, each rower (or oarsman) holds two oars, one in each hand, while in sweep rowing each rower holds one oar with both hands. There are several boat classes in which athletes may compete, ranging from single sculls, occupied by one person, to shells with eight rowers and a coxswain (rowing), coxswain, called eight (rowing), eights. There are a wide variety of course types and formats of racing, but most elite and championship level racing is conducted on calm water courses long with several lanes marked using buoys. Modern rowing as a competitive sport can be traced to the early 17th century whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
