What is the evolutionary significance of the endostyle in chordates?

The swim bladder in bony fishes is primarily involved in which function?

The turret shown rotates w.r.t the ground at a constant [a] rad/s in the +y direction.  Simultaneously the barrel pitches up wr.t. the turret at a constant [b] rad/s in the +z direction.  If the barrel is a [L] m long slender rod (Ig=1/12*m*L2, Ia=1/3*m*L2), find the magnitude of the reaction moment at point A in N*m at the instant shown. The barrel’s mass is [m] kg and the CG is halfway between A and B.  Use g=10m/s2 down.   Include a diagram and all steps in your work.
