The cross bridge cycle starts when

a) ca2+ is actively transported into the sarcoplasmic reticulum
b) ca2+ from the sarcoplasmic reticulum binds to troponin
c) atp binds to troponin and is hydrolyzed to adp
d) pi ca2+ from the sarcoplasmic reticulum binds to tropomyosin
e) acetylcholine diffuses away from the synaptic cleft

Part 1: include important facts found through your research. part 2: include your visual display. include your summary of “the chemistry of water” from the national science foundation website. include your experiment. part 3: include responses to the reflection questions.

You have a liquid that exhibits diltancy. you want to pour it from a bottle. what should you do to the bottle before pouring

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
