Problem: Most bacterial species are either spherical, called cocci (sing. coccus, from Greek kokkos, grain, seed), or rod-shaped, called bacilli (sing. bacillus, from Latin baculus, stick). Elongation is associated with swimming. Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of species even have tetrahedral or cuboidal shapes. More recently, some bacteria were discovered deep under Earth's crust that grow as branching filamentous types with a star-shaped cross-section. The large surface area to volume ratio of this morphology may give these bacteria an advantage in nutrient-poor environments. This wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and is important because it can influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids and escape predators.
What shape was newly discovered bacteria from deep under Earth?
The answer is the following: branching filamentous types with a star-shaped cross-section

Problem: According to Greek law, every Sunday of the year is a public holiday. In addition, there are four mandatory official public holidays: 25 March (Greek Independence Day), Easter Monday, 15 August (Assumption or Dormition of the Holy Virgin), and 25 December (Christmas). 1 May (Labour Day) and 28 October (Ohi Day) are regulated by law as being optional but it is customary for employees to be given the day off. There are, however, more public holidays celebrated in Greece than are announced by the Ministry of Labour each year as either obligatory or optional. The list of these non-fixed national holidays rarely changes and has not changed in recent decades, giving a total of eleven national holidays each year.
How many Greek national holidays are there each year?
The answer is the following: eleven

Problem: At the other extreme mountainous regions can be windy, cold, and areas at elevation of 750 meters or more (same elevation as Jerusalem) will usually receive at least one snowfall each year. From May to September, rain in Israel is rare. With scarce water resources, Israel has developed various water-saving technologies, including drip irrigation. Israelis also take advantage of the considerable sunlight available for solar energy, making Israel the leading nation in solar energy use per capita (practically every house uses solar panels for water heating).
Who leads the nation in solar energy use?
The answer is the following: Israel

Problem: Beyonce Giselle Knowles was born in Houston, Texas, to Celestine Ann "Tina" Knowles (nee Beyince), a hairdresser and salon owner, and Mathew Knowles, a Xerox sales manager. Beyonce's name is a tribute to her mother's maiden name. Beyonce's younger sister Solange is also a singer and a former member of Destiny's Child. Mathew is African-American, while Tina is of Louisiana Creole descent (with African, Native American, French, Cajun, and distant Irish and Spanish ancestry). Through her mother, Beyonce is a descendant of Acadian leader Joseph Broussard. She was raised in a Methodist household.
Where did Beyonce get her name from?
The answer is the following:
her mother's maiden name
