Final Quiz) | Liberty University
1. Which of the following properties of water allows it to move upward through a plant’s
vascular system?
A. High specific heat
B. Cohesion and adhesion
C. Density as a solid
D. Solvent versatility
Correct Answer: B
Explanation: Cohesion refers to the attraction between water molecules, while adhesion is
the attraction between water and the cell walls. These two forces work together to pull
water against gravity in a process called capillary action. This property is vital for the
survival of terrestrial plants that need to transport water from roots to leaves.
2. In a Biblical worldview, the ‘Creation Mandate’ refers to which human responsibility?
A. Total consumption of natural resources for human gain
B. Prioritizing technological advancement above all
C. Allowing nature to take its course without interference
D. Exercising wise stewardship over the Earth
,Correct Answer: D
Explanation: The Creation Mandate is derived from Genesis 1:28, where God commands
humans to be fruitful and have dominion over the earth. This dominion is understood as
stewardship, meaning humans must care for and manage the environment responsibly. It
emphasizes a balanced relationship between utilizing resources and preserving the
integrity of God’s creation.
3. Which organelle is responsible for the synthesis of proteins that will be secreted from the
cell?
A. Smooth endoplasmic reticulum
B. Rough endoplasmic reticulum
C. Lysosome
D. Nucleolus
Correct Answer: B
Explanation: The rough endoplasmic reticulum is studded with ribosomes, which are the
sites of protein synthesis. Proteins destined for secretion are synthesized here and then
transported to the Golgi apparatus for further processing. This organelle plays a critical
role in the endomembrane system of eukaryotic cells.
4. What is the primary function of enzymes in biological reactions?
A. Increasing the energy of the reactants
B. Changing the final equilibrium of the reaction
, C. Serving as a permanent reactant in the process
D. Lowering the activation energy
Correct Answer: D
Explanation: Enzymes act as biological catalysts that speed up chemical reactions without
being consumed. They achieve this by lowering the activation energy barrier required for a
reaction to proceed. This allows metabolic processes to occur at rates sufficient to sustain
life at body temperature.
5. Which phase of the cell cycle involves the replication of DNA?
A. G1 phase
B. G2 phase
C. S phase
D. M phase
Correct Answer: C
Explanation: The S phase, or synthesis phase, is the period during interphase when the cell
duplicates its genetic material. Ensuring an exact copy of DNA is made is crucial before the
cell proceeds to mitosis. Errors during this phase can lead to mutations or cell death during
division.
6. In Mendelian genetics, an organism with two different alleles for a trait is described as:
A. Homozygous dominant
