Kinesin-1 motors can move long distances on microtubule tracks without dissociating. by contrast, myosin ii motors in skeletal muscle take only one or a few steps before letting go. what is most likely the difference between these two motors that allow two different types of movement?
o differences in length of the stalk of each respective motor allow for differences in step size.
o differences in atp versus gtp hydrolysis alter the motor head movement along filaments.
o actin filaments are smaller in diameter and have less space for movement.
o binding affinity of the kinesin-1 motor head to microtubules is high, whereas binding affinity of the myosin ii motor head to actin filaments is low.
o microtubules are larger in diameter and have more space for movement.

What evidence could be used to convince policy makers to change a shipping lane from going through a whale breeding ground? information on the number of all whale species currently alive information on the number of all whales hit by boats in the given area information on the number of whale deaths in the world's oceans information on the number of whale offspring born every year. (a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas. (d) scientists work together and use past data to show that some fish populations are adapting to environmental changes.
