Which of the following is not a unique property of water?
A. High cohesion and adhesion
B. High surface tension
C. High density upon melting
D. High freezing point
(D.) High freezing point
, Water's unique properties are due to intermolecular hydrogen bonding. These forces make
water molecules "stick" to one another which also increases surface tension. Water has a low
freezing point due to the fact that molecules have a very low kinetic energy to arrange
themselves in the lattice-like structure found in ice
What is a metabolic reaction that releases energy called?
Answer: Catabolic reaction
Catabolic reactions release energy and are exothermic. Catabolism breaks down complex
molecules into simpler molecules.
What organic compounds facilitate chemical reactions by lowering activation energy?
Answer: Enzymes
Enzymes that drive these reactions are protein catalysts. Enzymes have near exact specificity
with their substrate (reactant). Product is formed in the reaction while the enzyme is unchanged
and ready to be reused
Which structure is exclusively in eukaryotic cells?
A. Cell wall
B. Nucleus
C. Cell membrane
D. Organelles
(B.) Nucleus
Animal, plant, fungi, and protist cells are all eukaryotic. DNA is contained within the nucleus of
eukaryotic cells, and they also have membrane-bound organelles. Prokaryotic cells (archaea and
bacteria) do not have a nucleus or other membrane-bound organelles
