Question

what did charles darwin propose after observing the 11 - inch - long nectaries of the angraecum sesquipedale orchid in madagascar? that the orchid was a self - pollinator and required no assistance from an organism that the orchid must reproduce asexually that the orchid was an evolutionary dead end and could no longer reproduce the presence of very small bees that can fit into a long nectar tube the existence of a pollinator moth with a proboscis of 10 - 11 inches clear my selection 23 multiple choice 4 points which of these is not a required characteristic of life? structural organization locomotion homeostasis

Explanation:

Charles Darwin, observing the long nectaries of the Angraecum sesquipedale orchid, hypothesized the existence of a pollinator with a long enough proboscis to reach the nectar and aid in pollination. For the second question, structural organization and homeostasis are key characteristics of life, while locomotion is not a universal requirement for all life - forms.

Answer:

1. E. the existence of a pollinator moth with a proboscis of 10 - 11 inches
2. B. locomotion
