Which of the following is not a nanoscale object? a sugar molecule an oxygen atom

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.
