Problem: Please answer a question about the following article about Race (human categorization):
The authors of the study also examined 77 college textbooks in biology and 69 in physical anthropology published between 1932 and 1989. Physical anthropology texts argued that biological races exist until the 1970s, when they began to argue that races do not exist. In contrast, biology textbooks did not undergo such a reversal but many instead dropped their discussion of race altogether. The authors attributed this to biologists trying to avoid discussing the political implications of racial classifications, instead of discussing them, and to the ongoing discussions in biology about the validity of the concept "subspecies". The authors also noted that some widely used textbooks in biology such as Douglas J. Futuyama's 1986 "Evolutionary Biology" had abandoned the race concept, "The concept of race, masking the overwhelming genetic similarity of all peoples and the mosaic patterns of variation that do not correspond to racial divisions, is not only socially dysfunctional but is biologically indefensible as well (pp. 5 18-5 19)." (Lieberman et al. 1992, pp. 316–17)
What did Douglas J. Futuyama consider the concept of race as not only being socially dysfunctional but this as well?
A: biologically indefensible
Problem: Please answer a question about the following article about Gene:
The transcribed pre-mRNA contains untranslated regions at both ends which contain a ribosome binding site, terminator and start and stop codons. In addition, most eukaryotic open reading frames contain untranslated introns which are removed before the exons are translated. The sequences at the ends of the introns, dictate the splice sites to generate the final mature mRNA which encodes the protein or RNA product.
What do most eukaryotic open reading frames contain?
A: untranslated introns
Problem: Please answer a question about the following article about Protestantism:
Although the Reformation was a religious movement, it also had a strong impact on all other aspects of life: marriage and family, education, the humanities and sciences, the political and social order, the economy, and the arts. Protestant churches reject the idea of a celibate priesthood and thus allow their clergy to marry. Many of their families contributed to the development of intellectual elites in their countries. Since about 1950, women have entered the ministry, and some have assumed leading positions (e.g. bishops), in most Protestant churches.
What religious movement affected education, politics, the economy, and marriage?
A: the Reformation
Problem: Please answer a question about the following article about Adolescence:
Romantic relationships tend to increase in prevalence throughout adolescence. By age 15, 53% of adolescents have had a romantic relationship that lasted at least one month over the course of the previous 18 months. In a 2008 study conducted by YouGov for Channel 4, 20% of 14−17-year-olds surveyed revealed that they had their first sexual experience at 13 or under in the United Kingdom. A 2002 American study found that those aged 15–44 reported that the average age of first sexual intercourse was 17.0 for males and 17.3 for females. The typical duration of relationships increases throughout the teenage years as well. This constant increase in the likelihood of a long-term relationship can be explained by sexual maturation and the development of cognitive skills necessary to maintain a romantic bond (e.g. caregiving, appropriate attachment), although these skills are not strongly developed until late adolescence. Long-term relationships allow adolescents to gain the skills necessary for high-quality relationships later in life and develop feelings of self-worth. Overall, positive romantic relationships among adolescents can result in long-term benefits. High-quality romantic relationships are associated with higher commitment in early adulthood and are positively associated with self-esteem, self-confidence, and social competence. For example, an adolescent with positive self-confidence is likely to consider themselves a more successful partner, whereas negative experiences may lead to low confidence as a romantic partner. Adolescents often date within their demographic in regards to race, ethnicity, popularity, and physical attractiveness. However, there are traits in which certain individuals, particularly adolescent girls, seek diversity. While most adolescents date people approximately their own age, boys typically date partners the same age or younger; girls typically date partners the same age or older.
How many percent of adolescents have had a romantic relationship lasting one month or longer by age 15?
A:
53%
