Kingdom Animalia Questions!!!

Postby Liquidpyro » Wed Apr 12, 2006 4:17 pm

Hey I have a few questions on a biology worksheet I am doing. Any help would be greatly appreciated.

1. What is 1 advantage and 1 disadvantage of being a hermaphrodite?

2. The eggs of different animal species cary geartly in size depending on...
a. whether the egg and sperm are haploid or diploid
b. how long the food supply in the yolk must last
c. the number of chromosomes in the egg
d. the number of chromosomes in the sperm

3. Animals in which the anus develops in from the blastopore include...
a. Mollusks
b. arthropods
c. annelids
d. chordates

4. What features of development indicate that echinoderms and chordates are more closely related to each other than they are to other animals?

5. Why is it important to have a mechanism that prevents more than one sperm from entering an egg?



That's it.

Any help is greatly appreciated.

Thanks alot

Give us what you think, tell us your problem, and we'll help. But we won't do your exercises for you.
