The theory of force generation proposed (microfilaments can generate force, even in the absence of myosin, by elongating and pushing against a structure such as the plasma membrane) (also cytochalasins inhibit microfilament growth)is best supported by which of the following observations about amoeba locomotion? a. amoeboid movement stops upon expose to cytochalasins. b. amoeboid movement cannot occur if mitosis is blocked. c. moving amoeba cells produce more troponin than do stationary ones. d. the rate of movement is inversely proportional to the viscosity of the medium in the amoeba moves.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
