Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosiona period during which the majority of multicellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. In the Carboniferous, rainforest collapse led to a great loss of plant and animal life. The PermianTriassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the CretaceousPaleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the dinosaurs.
How many mass extinctions have happened since Life began on Earth?
A: five major mass extinctions

Rome offers no native creation myth, and little mythography to explain the character of its deities, their mutual relationships or their interactions with the human world, but Roman theology acknowledged that di immortales (immortal gods) ruled all realms of the heavens and earth. There were gods of the upper heavens, gods of the underworld and a myriad of lesser deities between. Some evidently favoured Rome because Rome honoured them, but none were intrinsically, irredeemably foreign or alien. The political, cultural and religious coherence of an emergent Roman super-state required a broad, inclusive and flexible network of lawful cults. At different times and in different places, the sphere of influence, character and functions of a divine being could expand, overlap with those of others, and be redefined as Roman. Change was embedded within existing traditions.
To the Romans who ruled all aspects of heaven and earth?
A: immortal gods

The school broke off from the University of Deseret and became Brigham Young Academy, with classes commencing on January 3, 1876. Warren Dusenberry served as interim principal of the school for several months until April 1876 when Brigham Young's choice for principal arriveda German immigrant named Karl Maeser. Under Maeser's direction the school educated many luminaries including future U.S. Supreme Court Justice George Sutherland and future U.S. Senator Reed Smoot among others. The school, however, did not become a university until the end of Benjamin Cluff, Jr's term at the helm of the institution. At that time, the school was also still privately supported by members of the community and was not absorbed and sponsored officially by the LDS Church until July 18, 1896. A series of odd managerial decisions by Cluff led to his demotion; however, in his last official act, he proposed to the Board that the Academy be named "Brigham Young University". The suggestion received a large amount of opposition, with many members of the Board saying that the school wasn't large enough to be a university, but the decision ultimately passed. One opponent to the decision, Anthon H. Lund, later said, "I hope their head will grow big enough for their hat."
What college did BYU separate from to become its own entity?
A: University of Deseret

Primary resistance occurs when a person becomes infected with a resistant strain of TB. A person with fully susceptible MTB may develop secondary (acquired) resistance during therapy because of inadequate treatment, not taking the prescribed regimen appropriately (lack of compliance), or using low-quality medication. Drug-resistant TB is a serious public health issue in many developing countries, as its treatment is longer and requires more expensive drugs. MDR-TB is defined as resistance to the two most effective first-line TB drugs: rifampicin and isoniazid. Extensively drug-resistant TB is also resistant to three or more of the six classes of second-line drugs. Totally drug-resistant TB is resistant to all currently used drugs. It was first observed in 2003 in Italy, but not widely reported until 2012, and has also been found in Iran and India. Bedaquiline is tentatively supported for use in multiple drug-resistant TB.
In what country was the first case of totally drug-resistant tuberculosis?
A:
Italy
