The researchers' experimental hypothesis was that changes in actin and myosin overlap would alter the number of myosin cross- bridges that could form within a sarcomere, and specifically that primer section key terms oa. increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths. b. increases in overlap disrupt cross-bridge formation, reducing c. differences in overlap and cross-bridge formation have little d. overlap is minimal at intermediate sarcomere (and muscle e. none of the other answer options is correct

explanation:

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
