Review the discussion of evolution and the Investigating Life feature. Which of the following statements is/are most likely true? (Select all that apply.) Moths that could smell the nectar at the bottom of the orchid saw the need for a longer tongue, so they grew one that reached the nectar and passed on the longer tongue to their offspring. Moths that could smell the nectar at the bottom of the orchid mated with females that had longer tongues so that their offspring might have a chance to reach the nectar. At least one moth species has always been able to reach the nectar of the orchid. Moths with longer tongues are more likely to have access to the orchid nectar and are therefore more likely to survive to reproduction. Orchids with deeper nectaries are more likely to have moths rub against their pollen, and are therefore more likely to reproduce, than orchids with shallow nectaries.
