A muscle cell
Explanation:
Nanoscale objects are the objects which have a size of order 10⁻⁹ m.
Some examples of Nanoscale objects are:
Molecules, atoms, human DNA, enzymes.
Molecules like sugar - about 1-2 nanometers.
Atoms which have a size of about 0.5 nm.
Enzyme ≈ 2.5 nanometers in diameter.
A muscle cell is large (1 – 40 mm in length and 10 – 50 μm in width) and is not a nanosacle object.
If a carbon atom is bonded to two hydrogen atoms and two carbon atoms, the type of bond that must exist between carbon atoms is a single bond. Single bonded carbon atoms are called sigma bonds.
