Student A trаveled аt а velоcity оf 12 m/s when she dоve off the board. Student B dove off the board at a velocity of 14 m/s. 1. Who had the greater kinetic energy? Your [answer1] should be "Student A" OR "Student B." Do not write anything else. 2. How much greater was that student's energy? (In other words, how many more units of energy did that student have?) Give a numerical [answer2] and don't forget your units!

Exаm Questiоn: The mаssive spreаd оf SARS-CоV-2 during the current coronavirus pandemic has led to the evolution of many new strains. In the fall of 2023, a new highly mutated strain BA.2.86 was identified, possessing nearly 30 mutations on its spike protein. Like a number of other important variants, this strain was thought to have evolved in an immunocompromised individual unable to clear their SARS-CoV-2 infection. Vaccines against SARS-CoV-2, including the newly updated one available in fall 2023 designed for the XBB.1.5 recombinant strain, target the viral spike protein. There was concern antibodies would be less effective against BA.2.86 and its descendants, including the even further mutation JN.1 strain surging toward dominance near the end of 2023 and helping drive a winter surge in the U.S. Copyright 2023 by Dr. Jonathan A.

Why might antibodies be less effective against BA.2.86 and its subvariants such as JN.1 than against previous strains? Explain. 2. Assume antibodies resulting from vaccination prove less effective against this new set of highly mutated variants. Would a reduced antibody response mean a vaccinated individual would not be protected at all from BA.2.86, JN.1 etc., e.g., like an unvaccinated person? What other players of your immune system could still respond and provide protection even if your antibody response was not especially effective? Explain, including references to components of the immune system you think would offer protection. Please number your answers 1 and 2 and explain briefly but thoroughly.
