What type of reproductive strategy is shown in the model and what is an evolutionary disadvantage of it?
O A. Asexual reproduction; organisms that utilize this strategy have increased genetic diversity which increases their ability to adapt to
frequent changes.
B. Sexual reproduction; organisms that utilize this strategy have increased genetic diversity which increases their ability to adapt to
frequent changes.
C. Sexual reproduction; organisms that utilize this strategy lack genetic diversity which limits their ability to adapt to frequent
changes.
D. Asexual reproduction; organisms that utilize this strategy lack genetic diversity which limits their ability to adapt to frequent
changes.

Review the discussion of evolution and Investigating Life 1.1. Which of the following statements is/are most likely
true? (Select all that apply.)

A
Check 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.

F4
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.
