Answer the following question given this paragraph: called growth factors signal some cells at the edge of the ectoderm to become epidermis cells. The remaining cells in the center form the neural plate. If the signaling by growth factors were disrupted, then the entire ectoderm would differentiate into neural tissue. The neural plate undergoes a series of cell movements where it rolls up and forms a tube called the neural tube, as illustrated in Figure 43.28. In further development, the neural tube will give rise to the brain and the spinal cord. Q: The neural plate undergoes a series of cell movements where it rolls up and forms a tube called what? Choices: - cell tube - occular tube - peripheral tube - neural tube A:
(Answer)
neural tube

Question: Answer the following question given this paragraph: Monsoons are like land and sea breezes, but on a larger scale. They occur because of seasonal changes in the temperature of land and water. In the winter, they blow from land to water. In the summer, they blow from water to land. In regions that experience monsoons, the seawater offshore is extremely warm. The hot air absorbs a lot of the moisture and carries it over the land. Summer monsoons bring heavy rains on land. Monsoons occur in several places around the globe. The most important monsoon in the world is in southern Asia ( Figure below ). These monsoons are important because they carry water to the many people who live there. Q: Where does the most important monsoon in the world occur? Choices: - the atlantic ocean - eastern aisa - northern africa - southern asia A:
Answer:
southern asia
