Which of the following is a consequence of ocean acidification? O A) Carbonate (CO32-) accumulates to increase the pH of the water.
B) Shorebird eggs are weakened and break more easily.
Marine organisms that use carbonate (CO32-) as a building block to make
calcified shelters are threatened.
D) Swimmers may experience skin irritation from the acidified water.

Which of the dna typing techniques do you think you would choose if you had to analyze a dna sample? why?

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
