When a robin tries to pull an earthworm out of the ground,
the worm uses its bristles to hold on tight to the walls of its
home. Sometimes the worm holds on so tight and the robin
pulls so hard that the worm breaks apart. The robin keeps
the front end and the hind end wriggles back into its tunnel.
If the bird only pulled off the first seven or eight segments
of the worm's body, a new head will grow. If the worm is
pulled in half, the tail end will die or produce another tail.
The double-tailed worm will starve to death. Only a head
end can regrow a tail to become a complete worm again.
All of the following are true regarding regeneration in
earthworms except

A) each earthworm will have exactly half the number of the
original chromosomes.
B) stem cells in each earthworm segment divide and
differentiate to provide the required missing tissue.
C) regenerated earthworms are genetically identical to its
separated segment.
D) earthworms are able to regenerate because their body
systems are relatively simple compared to more complex
organisms that cannot regenerate.

SAMPLE ANSWER: The processes of cell division are essentially the same except plant cells need to form a cell wall to complete
cell division, and chloroplasts are divided between the daughter cells during cytokinesis.

SAMPLE ANSWERS: If a person holds his\her breath too long, carbon dioxide can build up in the body. The person would then
faint and normal breathing would start to automatically restore oxygen levels. OR TSH increases thyroxin production and
thyroxin slows TSH production.
