- QUESTION 34 During fruit fly development, a transmembrane protein called Delta on the surfaces of presumptive neurons binds to a receptor, called Notch, on the surfaces of the immediately adjacent cells. This signals to the adjacent cells not to differentiate into neurons. This mode of signaling is: juxtacrine paracrine autocrine endocrineQUESTION 16 Match the definitions and key words with the group name (programmed or stochastic). From the drop down boxes, choose the correct letter (A -- Programmed or B -- Stochastic). Celluar Aging: suggesting that the lifespan of a species is determined by an internal cellular "clock" that limits the number of cell divisions. Immune System: suggesting that aging is due to a break-down in the body's natural defense system against bacteria, viruses, and other substances. Error Theory: suggesting that errors at the cellular level produce "faulty" molecules. Evolutionary theory: suggesting that aging is a natural way to limit the reproductive potential and timespan of members of a species. Wear and Tear: suggesting that like a battery or a machine, the human…Question 24 pts When we are vaccinated against SARS-CoV-2, what happens?
