Answer:
Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin.
Explanation:
Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available.
Answer: Yes, your answer is correct.
The answer is H—F. Fluorine is the most electronegative of the four halogens (and, in fact, of all the elements), so it does the best job of gathering the shared electrons to itself. Therefore, the bond with F is the most polar
Answer : The molar concentration of solution is 
Explanation :
Using Beer-Lambert's law :
where,
A = absorbance of solution = 0.614
C = molar concentration of solution = ?
l = path length = 1.0 cm
= molar absorptivity coefficient = 
(assume)
Now put all the given values in the above formula, we get:
Therefore, the molar concentration of solution is
