In the relaxed state, what prevents myosin from binding actin?

Tropomyosin covers myosin binding sites on actin and prevents myosin to bind to actin. When a neurotransmitter stimulates the muscle, an action potential travels down the T tubuals to the sarcomere reticulum and opens the calcium voltage-gated channels on sarcomere reticulum and calcium (Ca2+) rushes out and binds to troponin complex and that releases the tropmyosin form myosin binding sites so myosin binds to actin and contracts the muscle.

LDS, mormons, what does this verse mean?? stones?

Cool, I want a seer stone. I'm not Christian but the more and more I look at my ex LDS faith it seems like an evil tool that pulls people away from Christianity. Christianity teaches that only through Christ it is possible to be saved... period. LDS teach that through your own works and suffering using your priesthood and your personal ability to receive revelation from God you may obtain something better than just being "saved". LDS don't like to praise Christ's death which in Christian teaching it is his death that was the greatest gift to the people. Through his death we were saved. But the LDS again don't like that the people of this earth were the only ones wicked enough to kill Christ. Maybe that is why they Mormons are seen as unChristian by some.

Isn't that crazy that some doctors who specialize make a base salary of 700k?

The medical industry is not just recession proof, it's also a road to financial freedom. Sure, there are rich doctors (just as there are rich actors, CEOs and so on) but not everyone gets that kind of money. Most of the doctors I know make just as such as someone on 9-5. Unless they are cosmetic surgeons or neurosurgeons, it's hard for a regular doctor to hit pay gold.
