In regards to the structure of microtubules in cilia, you would expect to find the [A] arrangements at the tip, the [B] arrangement in the transitional zone, and the [C] arrangement in the basal body.   Word bank – just use the number associated with each selection: 1 = 9 doublets only. 2 = 9 triplets. 3 = 9 triplets + 2 central singlets. 4 = 9 doublets + 2 central singlets

Frog skeletal muscle contains thick filaments that are 3.0um long and thin filaments 2.0 um long.  If the uncontracted sarcomere is 4.4 um long, and the contracted sarcomere is 3.4 um long, what is the length of the A bands in micrometers [1]  and I bands [2] before contraction?  And after contraction what is the size of the A band [3] and I bands [4] in micrometers?  Your answer should be a number with one figure after a decimal point like 1.0 or 1.1 as examples.
