Given these structures:

1. whole muscle
2. muscle fiber (cell)
3. myofilament
4. myofibril
5. muscle fasciculus
choose the arrangement that lists the structures in the correct order from the largest to the smallest structure.

a) 1,5,2,4,3 b) 1,2,5,4,3 c) 1,5,2,3,4 d) 5,1,2,4,3

a) 1,5,2,4,3

Explanation: skeletal muscles function together with the skeleton to allow movement .a muscle is enclosed by a layer of connective tissue ,the epimysium.this connective tissue surrounds Smaller bundles called the fasciculi.

These fasciculi consist of still smaller multinucleated fibres.

These fibres consists of myofibrils which also consists of small protein filaments,the actin and myosin filaments.the myosin filaments are thicker than the actin filaments.

the endocrine system secretes hormones into blood and other body fluids. these chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. hormones provide feedback to the brain to affect neural processing. reproductive hormones affect the development of the nervous system.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
