Document Summary
Notes from review session for exam 3: lectures 25-36. Exchange system feedback loops (recognize + vs. loops) Not very specific , so many bacteria have flagellum (so tollike receptor will attack anything with flagellum. Just another way to activate the rest of the immune system. Some receptors recognize particular dna sequences found in viruses. In bees the males develop just as haploid. Have to get calcium wave going and it triggers development. In some cases where you bring them to diploid, you refuse the first polar body and egg together; sometime you start process of first mitosis and you don"t separate those chromosomes. 2 aspects to know: recognizing it"s an invagination (take a cell layer and then it buckles further, and eventually the cells pinch off and form a tube; all cells stay together until the very end) These overlying cells are ectoderm initially, with a notochord below, which sends signal to the ectoderm; the signal inactivates another signal called.
