Answer:
The different skeletal muscle fiber types vary in the speed and duration of their twitches due to -
b) They vary in the rate of hydrolysis of ATP
c) They vary in the removal of Ca+ from the cytosol
Explanation:
There are mainly two types of muscle fibers , i.e.
a) slow twitching, long contraction duration( type I fibers)
b) First twitching but short duration of contraction. ( type II fibers).
Now think of the physiology of muscle. Two components are important, cytosolic Ca++ concentration and Availability of ATP. K+ is related to the action potential ( none or all law, there is no relation to the duration with respect to the potassium). For long contraction muscle fibers need a more steady supply of ATP, and also consistent high concentration of cytosolic Ca++ for muscle contraction to happen. So, these two factor is important for the duration of twitching. So the answer is option f .
Answer: That sounds great!

Answer:
"Code Red" and "Code Blue" are both terms that are often used to refer to a cardiopulmonary arrest, but other types of emergencies (for example bomb threats, terrorist activity, child abductions, or mass casualties) may be given "Code" designations too. Colors, numbers, or other designations may follow a "Code" announcement to identify the type of emergency that is occurring.
