Overfishing of salmon has caused populations of wild salmon to decline. to combat this decline, salmon are raised in hatcheries, and then released to the wild. however, researchers have found that hatchery-raised salmon have reduced reproductive success in the wild, compared to wild salmon. they have also identified many genetic differences between hatchery-raised and wild salmon. which statement describes the most likely reason for the differences between hatchery-raised and wild salmon? a. the pressures of a hatchery environment and of the wild environment select for different traits. b. hatchery-raised salmon develop into stronger swimmers than those raised in the wild. c. the pressures of a hatchery environment promote convergent evolution between hatchery-raised and wild salmon. d. hatchery-raised salmon have evolved to have completely different genomes from those of wild salmon.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
