Q: Lake Tahoe never freezes. Since 1970, it has mixed to a depth of at least 1,300 ft (400 m) a total of 6 or 7 times. Dissolved oxygen is relatively high from top to bottom. Analysis of the temperature records in Lake Tahoe has shown that the lake warmed (between 1969 and 2002) at an average rate of 0.015 C per year. The warming is caused primarily by increasing air temperatures, and secondarily by increasing downward long-wave radiation. The warming trend is reducing the frequency of deep mixing in the lake, and may have important effects on water clarity and nutrient cycling.
Can we conclude that does lake tahoe freeze over in the winter?

Problem: Text: In the sixth-season episode ''Father's Day'', the twins meet their biological father, Matt Sullivan, and learn that he is white and a famous photojournalist. Matt never married their mother, Racelle Gavin, because they never got the chance: she had been asked to paint a mural in Florida and he had been assigned ''the opportunity of a lifetime'' in the Middle East. Also, Racelle told him that she would later join him in Tel Aviv without telling him of her pregnancy. After six months, Racelle suddenly stopped writing. When the girls' mother died, Matt was not allowed to see them because he couldn't prove he was their father. When he searched for his twin daughters, he never found them because they had been adopted by two different people.

A queen ant (formally known as a gyne) is an adult, reproducing female ant in an ant colony; generally she will be the mother of all the other ants in that colony. Some female ants, such as Cataglyphis cursor, do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning, and all of those offspring will be female. Others, like those in the genus Crematogaster, mate in a nuptial flight. Queen offspring develop from larvae specially fed in order to become sexually mature among most species. Depending on the species, there can be either a single mother queen, or potentially, hundreds of fertile queens in some species. Queen ants have one of the longest life-spans of any known insect -- up to 30 years. A queen of Lasius niger was held in captivity by German entomologist Hermann Appel for 2834 years; also a Pogonomyrmex owyheei has a maximum estimated longevity of 30 years in the field.
