Article: Video games are playable on various versions of iPods. The original iPod had the game Brick (originally invented by Apple's co-founder Steve Wozniak) included as an easter egg hidden feature; later firmware versions added it as a menu option. Later revisions of the iPod added three more games: Parachute, Solitaire, and Music Quiz.

Question: What is another phrase meaning hidden feature?
Ans: easter egg

Article: About 1150 species of fungi have been recorded from Antarctica, of which about 750 are non-lichen-forming and 400 are lichen-forming. Some of these species are cryptoendoliths as a result of evolution under extreme conditions, and have significantly contributed to shaping the impressive rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. The apparently simple morphology, scarcely differentiated structures, metabolic systems and enzymes still active at very low temperatures, and reduced life cycles shown by such fungi make them particularly suited to harsh environments such as the McMurdo Dry Valleys. In particular, their thick-walled and strongly melanized cells make them resistant to UV light. Those features can also be observed in algae and cyanobacteria, suggesting that these are adaptations to the conditions prevailing in Antarctica. This has led to speculation that, if life ever occurred on Mars, it might have looked similar to Antarctic fungi such as Cryomyces minteri. Some of these fungi are also apparently endemic to Antarctica. Endemic Antarctic fungi also include certain dung-inhabiting species which have had to evolve in response to the double challenge of extreme cold while growing on dung, and the need to survive passage through the gut of warm-blooded animals.

Question: How many of the extant fungi in Antarctica are lichen-forming?
Ans: 400

Article: DNA transposons generally move by "cut and paste" in the genome, but duplication has also been observed. Class 2 TEs do not use RNA as intermediate and are popular in bacteria, in metazoan it has also been found.

Question: What is a term that can describe how DNA transposons move?
Ans: cut and paste

Article: In May 1845, the Baptist congregations in the United States split over slavery and missions. The Home Mission Society prevented slaveholders from being appointed as missionaries. The split created the Southern Baptist Convention, while the northern congregations formed their own umbrella organization now called the American Baptist Churches USA (ABC-USA). The Methodist Episcopal Church, South had recently separated over the issue of slavery, and southern Presbyterians would do so shortly thereafter.

Question: Why did American Baptist congregations split?
Ans:
over slavery and missions
