Atoms are like the letters of the alphabet the compounds they make are like words.
Answer:
A. heavy nuclei
Explanation:
They absorb neuyrons in order to hain stability.
Answer:
Number of contraction cycles that could theoretically be fueled by the complete combustion of one mole of glucose is around 17
Explanation:
Energy released during the complete combustion of 1 mole glucose = 2870 kJ
Energy required/muscle contraction cycle = 67 kJ/contraction
Energy conversion efficiency = 39%
Actual amount of energy converted to contraction per mole of glucose is:

Total contraction cycles fueled by the above energy is:

Answer:
The correct answer is Polar structure. See the explanation below, please.
Explanation:
The water molecule is formed by the union of an oxygen atom (O) to two hydrogen atoms (H), forming at an angle of 105 °, having the negative electron density over the O and positive over the H. The water due to its polarity can interact with other equal molecules, by hydrogen bridge (occurs between the atom of H and an electronegative element, in this case the O). It corresponds to a type of dipole-dipole interaction.
