In fruit flies, a specific gene mutation causes the wings to become malformed. these wings are called vestigial because they do not function properly. the mutated allele for vestigial wings (v) is recessive to the allele for functioning wings (v). two fruit flies that are heterozygous for wing shape are crossed, resulting in many offspring.

which of the following would most likely describe the population of offspring?
about half of the offspring population has functioning wings, and the other half of the population has vestigial wings.

the majority of the offspring population has vestigial wings.

all of the offspring population have functioning wings.

the majority of the offspring population has functioning wings.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
