Answer 1

Thick filaments are definitely made of myosin for the first question (the other answers are all part of the contractile elements of a myofibril, but not made from myosin)

Answer 2

for question 2 Vitamin storage is not an essential part of the muscular system, this may have been set up to throw you off, since the skeletal system DOES store minerals (Ca2+)

The trapezius is a posterior (the back) trunk muscle. Its the big triangular muscle that reaches from your top cervical vertebrae, spine of the scapula and lower thoracic vertebrae
