QUES: In the groups Z/nZ introduced above, the element 1 is primitive, so these groups are cyclic. Indeed, each element is expressible as a sum all of whose terms are 1. Any cyclic group with n elements is isomorphic to this group. A second example for cyclic groups is the group of n-th complex roots of unity, given by complex numbers z satisfying zn = 1. These numbers can be visualized as the vertices on a regular n-gon, as shown in blue at the right for n = 6. The group operation is multiplication of complex numbers. In the picture, multiplying with z corresponds to a counter-clockwise rotation by 60°. Using some field theory, the group Fp× can be shown to be cyclic: for example, if p = 5, 3 is a generator since 31 = 3, 32 = 9 ≡ 4, 33 ≡ 2, and 34 ≡ 1.
What are groups called when element 1 is not primitive?

QUES: The Xbox 360 supports videos in Windows Media Video (WMV) format (including high-definition and PlaysForSure videos), as well as H.264 and MPEG-4 media. The December 2007 dashboard update added support for the playback of MPEG-4 ASP format videos. The console can also display pictures and perform slideshows of photo collections with various transition effects, and supports audio playback, with music player controls accessible through the Xbox 360 Guide button. Users may play back their own music while playing games or using the dashboard, and can play music with an interactive visual synthesizer.
When was the visual synthesizer added?

ANS: unanswerable

QUES: During the British Raj, famines in India, often attributed to failed government policies, were some of the worst ever recorded, including the Great Famine of 1876–78 in which 6.1 million to 10.3 million people died and the Indian famine of 1899–1900 in which 1.25 to 10 million people died. The Third Plague Pandemic in the mid-19th century killed 10 million people in India. Despite persistent diseases and famines, the population of the Indian subcontinent, which stood at about 125 million in 1750, had reached 389 million by 1941.
How many people died in the Indian Famine of 1899-1900?

ANS: 1.25 to 10 million

QUES: During mutualistic symbioses, the host cell lacks some of the nutrients, which are provided by the endosymbiont. As a result, the host favors endosymbiont's growth processes within itself by producing some specialized cells. These cells affect the genetic composition of the host in order to regulate the increasing population of the endosymbionts and ensuring that these genetic changes are passed onto the offspring via vertical transmission (heredity).
When the the host favors the endosymbiont's growth process what takes place?
