ANSWERS A+ GRADED
1. Which level of structural organization is the simplest, composed of
atoms and molecules?
A) Cellular level
B) Tissue level
C) Chemical level
D) Organ level
Answer: C) Chemical level
Explanation: The chemical level is the most fundamental level of
structural hierarchy, involving atomic and molecular components such
as water, proteins, and electrolytes. The cellular level arises when
molecules combine to form organelles and cells, making the chemical
level the simplest.
2. Which feedback mechanism amplifies a change in the body's
physiological condition away from the set point?
A) Negative feedback
B) Positive feedback
C) Intrinsic feedback
,2|Page
D) Feedforward control
Answer: B) Positive feedback
Explanation: Positive feedback loops amplify an initial stimulus, moving
the variable further from its original set point. A classic example is the
release of oxytocin during childbirth, which increases uterine
contractions until the baby is delivered. Negative feedback, by contrast,
opposes the change.
3. The anatomical term "antecubital" refers to which body region?
A) Armpit
B) Anterior elbow
C) Posterior knee
D) Neck
Answer: B) Anterior elbow
Explanation: The antecubital region is the anterior surface of the elbow,
commonly known as the cubital fossa. It is a common site for
venipuncture. The axillary region refers to the armpit, while popliteal
refers to the posterior knee.
4. Which type of chemical bond involves the sharing of electron pairs
between atoms?
A) Ionic bond
B) Hydrogen bond
C) Covalent bond
,3|Page
D) Van der Waals force
Answer: C) Covalent bond
Explanation: Covalent bonds form when atoms share one or more pairs
of valence electrons, creating strong, stable molecular structures such
as H2O. Ionic bonds involve the transfer of electrons, while hydrogen
bonds are weaker intermolecular attractions.
5. A solution with a pH of 8.0 has how many more hydroxyl ions (OH-)
compared to a neutral solution?
A) 0.1 times more
B) 2 times more
C) 10 times more
D) 20 times more
Answer: C) 10 times more
Explanation: The pH scale is logarithmic. A neutral pH is 7.0. A pH of 8.0
is one order of magnitude more alkaline, meaning the hydroxyl ion
concentration is 10 times higher than at pH 7.0.
6. Which organelle is primarily responsible for the synthesis of
adenosine triphosphate (ATP)?
A) Ribosome
B) Golgi apparatus
C) Lysosome
D) Mitochondrion
, 4|Page
Answer: D) Mitochondrion
Explanation: Mitochondria are the powerhouse of the cell, carrying out
oxidative phosphorylation and the citric acid cycle to produce ATP.
Ribosomes synthesize proteins, while the Golgi apparatus modifies and
packages proteins.
7. During which phase of mitosis do sister chromatids separate and
move to opposite poles?
A) Prophase
B) Metaphase
C) Anaphase
D) Telophase
Answer: C) Anaphase
Explanation: Anaphase is characterized by the splitting of the
centromere and the segregation of sister chromatids, now individual
chromosomes, pulled by spindle fibers toward the centrosomes.
Metaphase aligns chromosomes, and telophase involves nuclear
envelope reformation.
8. Which type of epithelium is specialized to accommodate stretching
and is found in the urinary bladder?
A) Stratified squamous
B) Simple columnar
C) Transitional
D) Pseudostratified columnar
