Zoology Semester 1 Final Practice

Which of the following is not a form of asexual reproduction?

• gemmulation

• fragmentation

• spawning

• budding

Which of the following animals reproduces by parthenogenesis?

• earthworms

• starfish

• frogs

• honey bees

Diploblasts do not develop

• endoderm

• mesoderm

• ectoderm

• all of these develop

Which of the following does not display radial symmetry?

• planaria

• box jelly

• starfish

• medusa

What do sponges eat?

• organic material

• plankton

• small fish

• all of these

Which part of a sponge digests the food?

• amoebocytes

• choanocytes

• spicules

• osculum

Which environment type favors external fertilization?

• desert

• arboreal

• aquatic

• none of these

Which of the following reproductive strategies allows for more variation in the population?

• external fertilization

• budding

• gemmulation

• fragmentation

Why is variation important for a population?

• Variety is the spice of life

• It allows for more offsrping

• It allows populations to adapt to a changing environment

• If the environment doesn't change, all organisms will be "fit"

In which situation would asexual reproduction be favored?

• unchanging environment

• aquatic environment

• desert

• changing environment
