Question: Dark meat, which avian myologists refer to as "red muscle", is used for sustained activitychiefly walking, in the case of a chicken. The dark colour comes from the protein myoglobin, which plays a key role in oxygen uptake and storage within cells. White muscle, in contrast, is suitable only for short bursts of activity such as, for chickens, flying. Thus, the chicken's leg and thigh meat are dark, while its breast meat (which makes up the primary flight muscles) is white. Other birds with breast muscle more suitable for sustained flight, such as ducks and geese, have red muscle (and therefore dark meat) throughout. Some cuts of meat including poultry expose the microscopic regular structure of intracellular muscle fibrils which can diffract light and produce iridescent colours, an optical phenomenon sometimes called structural colouration.
Is there an answer to this question: What causes the meat of some poultry to show rainbow like colr striations?

Answer: the microscopic regular structure of intracellular muscle fibrils which can diffract light and produce iridescent colours

Question: Uranium carbides and uranium nitrides are both relatively inert semimetallic compounds that are minimally soluble in acids, react with water, and can ignite in air to form U
3O
8. Carbides of uranium include uranium monocarbide (UC), uranium dicarbide (UC
2), and diuranium tricarbide (U
2C
3). Both UC and UC
2 are formed by adding carbon to molten uranium or by exposing the metal to carbon monoxide at high temperatures. Stable below 1800 C, U
2C
3 is prepared by subjecting a heated mixture of UC and UC
2 to mechanical stress. Uranium nitrides obtained by direct exposure of the metal to nitrogen include uranium mononitride (UN), uranium dinitride (UN
2), and diuranium trinitride (U
2N
3).
Is there an answer to this question: Along with uranium monocarbide and uranium dicarbide, what is a notable carbide of uranium?

Answer: diuranium tricarbide

Question: The USA PATRIOT Act increased the powers allotted to the FBI, especially in wiretapping and monitoring of Internet activity. One of the most controversial provisions of the act is the so-called sneak and peek provision, granting the FBI powers to search a house while the residents are away, and not requiring them to notify the residents for several weeks afterwards. Under the PATRIOT Act's provisions, the FBI also resumed inquiring into the library records of those who are suspected of terrorism (something it had supposedly not done since the 1970s).
Is there an answer to this question: Could the FBI inquire into library records?

Answer: FBI also resumed inquiring into the library records

Question: Ann Arbor has a typically Midwestern humid continental climate (Koppen Dfa), which is influenced by the Great Lakes. There are four distinct seasons: winters are cold with moderate to heavy snowfall, while summers are very warm and humid, and spring and autumn are short but mild. The area experiences lake effect weather, primarily in the form of increased cloudiness during late fall and early winter. The monthly daily average temperature in July is 72.6 F (22.6 C), while the same figure for January is 24.5 F (4.2 C). Temperatures reach or exceed 90 F (32 C) on 10 days, and drop to or below 0 F (18 C) on 4.6 nights. Precipitation tends to be the heaviest during the summer months, but most frequent during winter. Snowfall, which normally occurs from November to April but occasionally starts in October, averages 58 inches (147 cm) per season. The lowest recorded temperature was 23 F (31 C) on 11 February 1885 and the highest recorded temperature was 105 F (41 C) on 24 July 1934.
Is there an answer to this question: What was the lowest recorded temperature on 11 February 1858?

Answer:
unanswerable
