Again copied from my little brothers test. Is the Yahoo Community smart enough to get these right? Lets find out
1. Why do plants and animals that live in the water have a simpler reproductive process than the plants and animals that live on land?
2. Why are many kinds of fish very easily produced in fish hatcheries?
3. Why are egg cells in birds relatively few in number and large in size?
4. Describe the migrations made by salmon and eels for purposes of reproduction.
5. Describe the life history and reproduction of the common toad.
6. Why are hens' eggs very satisfactory for the study of embryology?
7. In what bilaterally symmetrical animals is there only one ovary?
8. Is fertilization necessary in the production of eggs?
9. Describe the development of the rabbit embryo from fertilization to birth.
10. Compare the differences in parental care in the case of fish, birds, and mammals.
