While doing research for a paper about metal exports, a
student finds information about copper mining in different countries in 1995
and 2020. The student notes that Peru produced 0.38 million metric tons of
copper in 1995 and______
Interested in how differences in the color of dogs'
irises affect human responses to dogs, Akitsugu Konno et al. showed close-up
images of dogs' faces to human participants and asked them to rate the dogs'
traits and their own attitudes toward the dogs. Konno et al. suggest that
differences in iris color led participants to view some dogs as more
vulnerable and in need of protection than others and that this phenomenon
could help explain the association the researchers observed between iris color
and participants' inclinations to interact with or keep dogs, as illustrated by
the finding that______
Neighboring Species and Target Species in Various Locations
In a study of interactions between plants, researchers
Carolina Laura Morales and Anna gathered data about flowering plants growing
alongside each other in various locations. In each case, the researchers
identified one plant as a "target species" and a nearby plant as a
"neighboring species. An example of a neighboring species is the musk thistle
which grows alongside the Peruvian lily in______
Neuroscientist Kiyohito ligaya and colleagues developed
a computational model to predict how much a person will enjoy a particular work
of art on a scale from 1 (not at all) to 4 (very much). They then recruited
participants to use the same scale to rate several sets of paintings in various
styles and calculated the correlation between the ratings predicted by the
model and those reported by the participants. Assuming participant P1 gave
equal ratings to the impressionist and color-field paintings, the data in the
graph suggest that the model predicted that______
Drosophila (fruit flies) have generation times of 10-12
days, so seasonal changes in humidity and other environmental conditions can
drive seasonal fluctuations in chromosome rearrangements in species such as D.
persimilis and D. mediopunctata. Drosophila body size (for which wing centroid
size serves as a proxy measure) correlates with life span. Banu Şebnem Önder
and Cansu Fidan Aksoy measured the wing sizes of members of a D. melanogaster
population in Yeşilöz, Turkey, that were collected monthly between May and
October over three years. Their research suggests that Drosophila collected in
relatively warmer months should tend to have a longer life span, as is
illustrated by the finding that______
