- Explain the changes in size and position of the frog blastocoel during gastrulation. (min. 5 sentences)Critical periods of fetal development Human nutrition starts during pregnancy, the moment the fertilized egg attaches itself to the uterine wall and starts receiving nutrients from the mother. At the placenta, the mother and the embryo exchange nutrients, oxygen and waste. In this way, the embryo receives the nutrition it needs to grow, and allows the mother to handle the processing of waste. The nutrients received by the embryo depend on the nutrients consumed by the mother in her current diet, as well as those in her nutrient reserves. If the mother lacks nutrients, the embryo will lack them as well. Red blood cells, bacteria and large proteins in the mother's blood cannot pass to the embryo, but some potentially dangerous substances can. Alcohol, caffeine, illicit drugs, prescription and over-the-counter medications can cross the placenta barrier and enter the embryo. Environmental pollutants such as mercury, arsenic and lead can cross the placenta barrier too. Some of these…Humans have three openings in an analogous place.
