3. The help m hurry plorganism in the photo is a daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults
range from less than 1 to 5 mm in length. They are good swimmers
and eat mostly algae. Daphnia become mature at 5 to 10 days, and an
adult female can produce up to 100 eggs every 3 or 4 days during its
2-month life span. When harmful algae rapidly increase in the daphnia's
environment, daphnia can develop adaptations to tolerate the
negative effects of the algae within 10 years.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
