Visit http://visembryo.com/baby/index.html and answer the following questions.
1. In embryo development stage 2, what type of replication are the first cells undergoing? What do you think would happen if a mutation occurred in one of these cells?
2. At about 16 days post-ovulation, what layer will give rise to the hair, nails, and skin?
3. Explain what a neural groove is, and at how many days post-ovulation does this form? What do you think might happen if this neural groove is not formed properly?
4. At what stage does the heart become a four-chambered heart? What do you think might occur if the heart does not completely differentiate into four different chambers?
5. During what stage is gender differentiated? What do you think might occur if the gender does not properly differentiate?
6. Describe two major developments that occur during stage 23.
7. During what week of development are the lungs completely capable of breathing air? Discuss genetic disorders involving the respiratory system?
8. Describe why an infant is born with 300 bones, while an adult has 206 bones. Discuss some birth defects that effect the skeletal system and identify if they are associated with a genetic condition.
9. Describe the development of the musculature in fetal development. Highlight any major genetic conditions involving the muscle system.
