background information: The slow block to polyspermy involves a permanent modification of the egg surface, usually through exocytosis of the cortical granules. In the 1970s, Dave Epel carried out experiments that led to the conclusion that a Ca2+ rise in the egg is both necessary and sufficient to trigger cortical granule exoctyosis (CGE).
Experiment (b) – Dr. Epel injects a small amount of Ca2+ into unfertilized eggs and observes CGE almost immediately
For the experiment above, is it an example of correlation, loss-of-function or gain-of function? Then, indicate the predicted result.
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…

In the 1970s, Dave Epel carried out experiments that led to the conclusion that a Ca2+ rise in the egg is both necessary and sufficient to trigger cortical granule exoctyosis (CGE).
Experiment (c) – Dr. Epel injects a calcium chelator (called EGTA; chelators act as specific “sinks” or “magnets” for ions) into unfertilized eggs and then adds sperm. The sperm bind and fuse with the eggs, but no CGE occurs.
For the experiment above, describe it as correlation, loss-of-function or gain-of function. Then, indicate the predicted result.

- Which statements are true? Explain why or why not.1 In the early cleavage stages, when the embryocannot yet feed, the developmental program is driven andcontrolled entirely by the material deposited in the egg bythe mother.2 Because of the many later developmental trans-formations that produce the elaborately structured organs,the body plan set up during gastrulation bears little resem-blance to the body plan in the adult.3 As development progresses, individual cellsbecome more and more restricted in the range of cell typesthey can give rise to.4 At different stages of embryonic development,the same signals are used over and over again by differentcells, but with different biological outcomes.5 Changes in the coding regions of genes involved indevelopment are primarily responsible for the differencesbetween species. 6 The cell cycle is the ticking clock that sets thetempo of developmental processes, with maturationalchanges in gene expression being dependent on cell-cycleprogression.arrow_forwardDraw the amphibian and avian unfertilized eggs.
