In 1994, Comcast became the third largest cable operator in the United States with around 3.5 million subscribers following its purchase of Maclean-Hunter's American division for $1.27 billion. The company's UK branch, Comcast UK Cable Partners, goes public while constructing a cable telecommunications network. With five other media companies, the corporation becomes an original investor in The Golf Channel. Following a bid in 1994 for $2.1 billion, Comcast increased its ownership of QVC from 15.5% of stock to a majority, in a move to prevent QVC from merging with CBS. Comcast later sold its QVC shares in 2004 to Liberty Media for $7.9 billion.
What percentage of CBS did Comcast own?

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?
A: alga genomes containing genes of bacterial origin

By 326 BC, Alexander the Great had conquered Asia Minor and the Achaemenid Empire and had reached the northwest frontiers of the Indian subcontinent. There he defeated King Porus in the Battle of the Hydaspes (near modern-day Jhelum, Pakistan) and conquered much of the Punjab. Alexander's march east put him in confrontation with the Nanda Empire of Magadha and the Gangaridai of Bengal. His army, exhausted and frightened by the prospect of facing larger Indian armies at the Ganges River, mutinied at the Hyphasis (modern Beas River) and refused to march further East. Alexander, after the meeting with his officer, Coenus, and learning about the might of Nanda Empire, was convinced that it was better to return.
At what battle did Alexander beat King Porus?
A: Battle of the Hydaspes

The structure of hardwoods is more complex. The water conducting capability is mostly taken care of by vessels: in some cases (oak, chestnut, ash) these are quite large and distinct, in others (buckeye, poplar, willow) too small to be seen without a hand lens. In discussing such woods it is customary to divide them into two large classes, ring-porous and diffuse-porous.
In wood from a willow tree, what would you need to use to see the tiny vessels?
A:
a hand lens
