Is this true or false?
a. Fertilization is followed by a cleavage, a period of rapid cell division without growth.
b. From the process above, this results in the production of a large number of cells called blastomeres.
c. In sexual reproduction, the offspring have the same combinations of genes as their parents.
d. Sequential hermaphroditism occurs when an animal is one sex during one phase of its lifecycle and the opposite sex during another phase
How does segmentation enhance annelid locomotion? a. Segmentation creates repeating body structures so the entire organism functions in synchrony. b. Segmentation allows specialization of different body regions. c. Neural segmentation allows annelids to localize sensations. d. Muscle contractions can be localized to specific regions of the body to coordinate movement.

- Compare and contrast adaptations displayed by animals and plants that enable them to survive in different environments.arrow_forwardModern sponges produce microscopic spicules (right) to deter predation but, as the earliest animals, they existed before any predators evolved; how might biologists interpret this observation? A. Spicules were probably absent in the earliest sponges and evolved later as predation began. B. Spicules performed other tasks in early sponges, possibly structural support, and were later modified for defense. C. Spicules were present in some sponge species and absent in others; predation became a selection pressure that eliminated some species entirely. D. All of the above are valid hypotheses.arrow_forwardParasitic flatworms can avoid their host’s immune response by employing which of the following? a. Diffusion b. Gastrodermal ingestion c.
