The area's many universities and colleges make Philadelphia a top international study destination, as the city has evolved into an educational and economic hub. With a gross domestic product of $388 billion, Philadelphia ranks ninth among world cities and fourth in the nation. Philadelphia is the center of economic activity in Pennsylvania and is home to seven Fortune 1000 companies. The Philadelphia skyline is growing, with several nationally prominent skyscrapers. The city is known for its arts, culture, and history, attracting over 39 million domestic tourists in 2013. Philadelphia has more outdoor sculptures and murals than any other American city, and Fairmount Park is the largest landscaped urban park in the world. The 67 National Historic Landmarks in the city helped account for the $10 billion generated by tourism. Philadelphia is the birthplace of the United States Marine Corps, and is also the home of many U.S. firsts, including the first library (1731), first hospital (1751) and medical school (1765), first Capitol (1777), first stock exchange (1790), first zoo (1874), and first business school (1881). Philadelphia is the only World Heritage City in the United States.

The concept of a gene continues to be refined as new phenomena are discovered. For example, regulatory regions of a gene can be far removed from its coding regions, and coding regions can be split into several exons. Some viruses store their genome in RNA instead of DNA and some gene products are functional non-coding RNAs. Therefore, a broad, modern working definition of a gene is any discrete locus of heritable, genomic sequence which affect an organism's traits by being expressed as a functional product or by regulation of gene expression.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can coding regions be split into?
Ah, so.. several exons

Hunting is claimed to give resource managers an important tool in managing populations that might exceed the carrying capacity of their habitat and threaten the well-being of other species, or, in some instances, damage human health or safety.[citation needed] However, in most circumstances carrying capacity is determined by a combination habitat and food availability, and hunting for 'population control' has no effect on the annual population of species.[citation needed] In some cases, it can increase the population of predators such as coyotes by removing territorial bounds that would otherwise be established, resulting in excess neighbouring migrations into an area, thus artificially increasing the population. Hunting advocates[who?] assert that hunting reduces intraspecific competition for food and shelter, reducing mortality among the remaining animals. Some environmentalists assert[who?] that (re)introducing predators would achieve the same end with greater efficiency and less negative effect, such as introducing significant amounts of free lead into the environment and food chain.

Ah, so..
