Problem: Horizontal gene transfer refers to the transfer of genetic material through a mechanism other than reproduction. This mechanism is a common source of new genes in prokaryotes, sometimes thought to contribute more to genetic variation than gene duplication. It is a common means of spreading antibiotic resistance, virulence, and adaptive metabolic functions. Although horizontal gene transfer is rare in eukaryotes, likely examples have been identified of protist and alga genomes containing genes of bacterial origin.
What is one example of horizontal gene transfer in eukaryotes?
---
Answer: alga genomes containing genes of bacterial origin


Problem: The five Great Lakes are located in the north-central portion of the country, four of them forming part of the border with Canada, only Lake Michigan situated entirely within United States. The southeast United States contain subtropical forests and, near the gulf coast, mangrove wetlands, especially in Florida. West of the Appalachians lies the Mississippi River basin and two large eastern tributaries, the Ohio River and the Tennessee River. The Ohio and Tennessee Valleys and the Midwest consist largely of rolling hills and productive farmland, stretching south to the Gulf Coast.
Which of the Great Lakes is entirely located in US territory?

Answer: Lake Michigan


Problem: Despite Magellan's visit, Guam was not officially claimed by Spain until January 26, 1565 by General Miguel López de Legazpi.:46 From 1565 to 1815, Guam and the Northern Mariana Islands, the only Spanish outpost in the Pacific Ocean east of the Philippines, was an important resting stop for the Manila galleons, a fleet that covered the Pacific trade route between Acapulco and Manila.:51 To protect these Pacific fleets, Spain built several defensive structures which are still standing today, such as Fort Nuestra Señora de la Soledad in Umatac. It is the biggest single segment of Micronesia, the largest islands between the island of Kyushu (Japan), New Guinea, the Philippines, and the Hawaiian Islands.
What was the name of the general who claimed Guam?
