What are the different levels of organization of a muscle down to myofilaments

the different levels of organisation of muscles down to myofilaments includes: molecular level and microscopic levels

Explanation:

The molecular level consist of actin and myosin( which forms the contractile units of the skeletal muscle). The actin and myosin filaments slide past each other to cause the shortening of a muscle fibre.

The microscopic level consist of sarcomere and myofibril. Sarcomere is the fundamental unit of muscle while the myofibrils consist of the myofilaments ( thick and thin filaments) which are organised into parallel units.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
