Young Great Horned owls hatch out in February (very early for most birds), and for the first four weeks incapable of leaving the nest. What type of offspring best fits the young owls? O Altricial Precocial

Antennal length, genetically controlled, is distributed in a beetle population as follows. In spring 1995, 45% have long antennae and 55% have short. In summer 1995, a fire sweeps through, randomly killing most of the population. In late summer 1995, the remaining beetles are measured again and it is found that 20% now have long antennae and 80% now have short antennae. Based on this, you can conclude that... Neither natural selection nor evolution has occurred, because there has not been enough time. Natural selection but NOT evolution has occurred with respect to antennae in this population. Natural selection and evolution have occurred with respect to antennae in this population Neither natural selection nor evolution has occurred, because there is no clear benefit to antennal length O Evolution but NOT natural selection has occurred with respect to antennae in this population.

Two groups of beetles live in the same forest and feed in the same trees, however one group mates in spring while the other mates in fall. They are not driven to mate outside of these seasons. Is this a prezygotic or post zygotic barrier? Postzygotic O Prezygotic

Although members of two neighboring groups of plants cross-pollinate and reproduce, continued cross-pollination among their offspring results in fewer and fewer numbers of seeds each successive generation. Is this a Prezygotic or post zygotic barrier? Prezygotic Postzygotic
