QUES: More than half of habitat for listed species is on non-federal property, owned by citizens, states, local governments, tribal governments and private organizations. Before the law was amended in 1982, a listed species could be taken only for scientific or research purposes. The amendment created a permit process to circumvent the take prohibition called a Habitat Conservation Plan or HCP to give incentives to non-federal land managers and private landowners to help protect listed and unlisted species, while allowing economic development that may harm ("take") the species.
When was it decided species could be taken for scientific purposes?

ANS: unanswerable

QUES: Emotions can motivate social interactions and relationships and therefore are directly related with basic physiology, particularly with the stress systems. This is important because emotions are related to the anti-stress complex, with an oxytocin-attachment system, which plays a major role in bonding. Emotional phenotype temperaments affect social connectedness and fitness in complex social systems (Kurt Kortschal 2013). These characteristics are shared with other species and taxa and are due to the effects of genes and their continuous transmission. Information that is encoded in the DNA sequences provides the blueprint for assembling proteins that make up our cells. Zygotes require genetic information from their parental germ cells, and at every speciation event, heritable traits that have enabled its ancestor to survive and reproduce successfully are passed down along with new traits that could be potentially beneficial to the offspring. In the five million years since the linages leading to modern humans and chimpanzees split, only about 1.2% of their genetic material has been modified. This suggests that everything that separates us from chimpanzees must be encoded in that very small amount of DNA, including our behaviors. Students that study animal behaviors have only identified intraspecific examples of gene-dependent behavioral phenotypes. In voles (Microtus spp.) minor genetic differences have been identified in a vasopressin receptor gene that corresponds to major species differences in social organization and the mating system (Hammock & Young 2005). Another potential example with behavioral differences is the FOCP2 gene, which is involved in neural circuitry handling speech and language (Vargha-Khadem et al. 2005). Its present form in humans differed from that of the chimpanzees by only a few mutations and has been present for about 200,000 years, coinciding with the beginning of modern humans (Enard et al. 2002). Speech, language, and social organization are all part of the basis for emotions.
 How many hundred years ago did the evolution of chimpanzees and humans diverge?

QUES: Following a steady decline, beginning in the late 1990s up through the mid-2000s, illicit drug use among adolescents has been on the rise in the U.S. Aside from alcohol, marijuana is the most commonly indulged drug habit during adolescent years. Data collected by the National Institute on Drug Abuse shows that between the years of 2007 and 2011, marijuana use grew from 5.7% to 7.2% among 8th grade students; among 10th grade students, from 14.2% to 17.6%; and among 12th graders, from 18.8% to 22.6%. Additional, recent years have seen a surge in popularity of MDMA; between 2010 and 2011, the use of MDMA increased from 1.4% to 2.3% among high school seniors. The heightened usage of ecstasy most likely ties in at least to some degree with the rising popularity of rave culture.
From the late 1990s to mid 2000s, was drug use in teens on the rise or decline?

ANS: decline

QUES: Interracial relationships have had a long history in North America and the United States, beginning with the intermixing of European explorers and soldiers, who took native women as companions. After European settlement increased, traders and fur trappers often married or had unions with women of native tribes. In the 17th century, faced with a continuing, critical labor shortage, colonists primarily in the Chesapeake Bay Colony, imported Africans as laborers, sometimes as indentured servants and, increasingly, as slaves. African slaves were also imported into New York and other northern ports by the Dutch and later English. Some African slaves were freed by their masters during these early years.
Who first imported slaves to New York?

ANS:
the Dutch
