Which statement best describes an important

process carried out by structure X?

• Milk passes from the mother to the fetus.

• Materials are exchanged between fetal and maternal

  blood.

• Maternal (mother's) blood is turned into fetal blood.

The fetus and the mother exchange materials between them such as oxygen, carbon dioxide, nutrients, and waste. This exchange of materials happens using the...

Which sequence best represents the correct order of events in the formation of a sexually reproduced individual?

• embryo → zygote → gamete → fetus

• zygote → embryo → fetus → gamete

• gametes → embryo → fetus → zygote

• gametes → zygote → embryo → fetus

Which organ is CORRECTLY paired with its function of human reproduction and development?

• Uterus : release of gametes

• Fallopian tubes : fertilization of gametes

• Umbilical Cord : implantation of the fetus

Which EARLY process happens during the ZYGOTE stage of human development?

• The zygote forms new organ systems

• The zygote takes in nutrients to grow larger and larger

• The zygote uses rapid Mitosis
