As a component of Carbohydrates, Oxygen is very important, too. Which of the following statements is incorrect about the way Oxygen behaves as part of a molecule?

The presence of oxygen in Carbohydrates makes them highly insoluble in water.

Oxygen has six outer valence electrons, and makes up to 2 bonds.

Oxygen is highly electronegative; it is an 'electron hog', sharing them unevenly.

The uneven sharing of electrons results in Oxygen forming polar covalent bonds.

Which of the following is NOT a role of Carbohydrates in a cell or organism?

formation of muscle tissues & bone in vertebrate bodies

provide energy, either immediate or long-term (storage)

Provide structure, support, and strength in certain organisms.

osmoregulation - moderating fluid balance in living organisms

Which statement about carbon is incorrect regarding its role as the basic building block of life?

Carbon is a very dense & heavy element, giving living things stability.

Carbon readily makes four stable bonds in single, double, or triple configurations.

Carbon is the least electronegative non-metal

Carbon has a high affinity for Oxygen & Hydrogen, which make bonds easily with C.
