A large cube and a small cube are made of granite of uniform density- The large cube has edges of length 1.2 meters and weighs 4.752 kilograms. If the small cube has edges of length 10 centimeters, what is the weight, in grains, of the small cube?

Larvae of many marine invertebrate species delay their metamorphosis into juveniles when cues signaling an appropriate juvenile environment are absent, thereby increasing their likelihood of thriving as juveniles and of ultimately reaching adulthood Nevertheless, delayed metamorphosis has potential costs for juveniles including reduced growth and increased mortality Nearly all evidence of such costs involves species whose larvae do not feed but rather subsist on stored nutrients, indicating that insufficient energy reserves may be an underlying cause of these costs. Supporting this hypothesis are laboratory studies showing that in a certain bryozoan. the prolonged larval swimming that results from delayed metamorphosis is associated with size reductions in the juvenile feeding organ (the lophophore) and that one factor influencing the size of juveniles of certain barnacle species is how long larvae delay metamorphosis However, other studies show that while significantly fewer juvenile Capitella worms survived to adulthood when metamorphosis had been delayed, prolonged larval swimming had no significant effect on juvenile size, suggesting, perhaps, that in some species, factors other than insufficient energy reserves account for the negative effects of the larval stresses that result from delayed metamorphosis.

The passage suggests that the, "bryozoan." the "barnacle species.'" and 'Capitella worms" all share which of the following characteristics?

Robert Philip argues that the advent of recorded music has directed performance style into a search for greater precision and perfection, with a consequent loss of spontaneity and warmth. Various expressive devices once common in classical music have been almost outlawed, including portamento (sliding from one note to another on a stringed instrument), playing the piano with the hands not quite synchronized, and flexibility of tempo. Philip fully documents these changes. However, other forces independent of recording were also at work. For example, the freedom of tempo so valued by Philip was. in its time, both a necessary expedient and disastrously abused. Recording alone did not cause the reaction against it. although hearing a particularly unintelligent use of it on disc may have reinforced the prejudice.

Hie author would most likely agree with which of the following statements about the "devices"?
