Answer to Question 1

1, 2, 4, 5
Rationale:
1. Protein is necessary to form the muscles of the fetus and to increase the tissues of the growing uterus and breasts of the mother.
2. This is a true statement. Poor iron intake can lead to maternal or fetal anemia.
3. Calcium is not related to constipation. Calcium is needed to form and calcify the fetal bones. If calcium intake is low, the mother's bones will demineralize to meet the needs of the fetus.
4. Zinc is involved in RNA and DNA synthesis, and milk production during lactation.
5. Vitamin A promotes healthy formation and development of the fetal eyes.

Answer to Question 2

1
Rationale:
1. Not all same-sex twins are identical or monozygotic, because fraternal, or dizygotic, twins can be the same gender or different genders.
2. When the zygote splits, identical twins share the same genotype result.
3. The only way to have twins of different genders is if they came from two separate fertilized ova. Monozygotic twins are identical, and are the same gender.
4. Monoamnionic-monochorionic twins are very rare, and occur as a result of the zygote splitting seven or more days after fertilization.
