Aforensic scientist examines a body that was discovered while still in a state of rigor mortis. in addition to environmental conditions when the body was found, what understanding will determine approximate time of death.

-The muscles will stay rigid until actin and myosin cross-bridges are destroyed.

-In the noncontracted state, troponin covers tropomyosin-binding sites on actin.

-T tubules help transmit the action potential to release calcium and start contraction.

Explanation:

For forensic science experts, the presence of rigor mortis helps in determining the time of death. It is the body muscles that normally help; if the body muscles are in a relaxed state for the first 3 hours after death, stiffens between 3 hours and 36 hours, and turns relaxed again. then the time of death can be traced easily.

in the united states, the president is controlled by the

constitution, and in all respects subordinate to it. insofar

as it deals with presidential power, however, the american

constitution has proved to be a highly malleable document.

with very few exceptions,' the constitutional provisions relating to the president have not been changed at all since

they were ratified in 1787. but in the late twentieth century, those provisions do not mean what they meant in

1787. the constitution is a legal document, and it is enforced judicially; but its meaning was hardly fixed when it

was ratified. in particular, the contemporary president has

far broader powers than the original constitution contemplated. it is remarkable but true that large-scale changes in

the authority of the president have been brought about

without changes in the constitutional text, but nevertheless

without significant illegality.

this is a paradox. is it not clear that constitutional

changes, if not textual, are illegal? the paradox has considerable relevance to our current thinking about the presidency in particular and about constitutionalism in general.

perhaps the framers of the american constitution feared

legislative power most of all; 2 but from well-known events

in the twentieth century, it is possible to conclude that it is

presidential power that holds out the greatest risks to both

liberty and democracy. the president is by far the most visible leader in the nation; he is often the only person in government with a national constituency. moreover, he is

he risk-return relationship. generally, the higher the potential return of an investment, the higher the risk. there is no guarantee that you will actually get a higher return by accepting more risk. diversification enables you to reduce the risk of your portfolio without sacrificing potential returns.
