BIOLOGY 1020 – FINAL EXAM (ZANZOT STYLE)


Questions 1–100


Questions 1–10: Scientific Method & Basic Chemistry
1. What is the first step in the scientific method?


A. Experimentation
B. Hypothesis formation
C. Observation
D. Data analysis


Answer: C. Observation

,Explanation: Science begins with observing a phenomenon.
Observations lead to questions, which guide hypothesis
formation.


2. A hypothesis must be:


A. Proven true
B. Testable and falsifiable
C. Widely accepted
D. Complex


Answer: B. Testable and falsifiable
Explanation: A valid hypothesis must be testable through
experiments and capable of being disproven.


3. What type of bond involves sharing electrons?


A. Ionic
B. Hydrogen
C. Covalent
D. Van der Waals

,Answer: C. Covalent
Explanation: Covalent bonds form when atoms share
electrons, creating stable molecules like water.


4. Water is a polar molecule because:


A. It is symmetrical
B. Oxygen attracts electrons more strongly
C. Hydrogen is larger
D. It has ionic bonds


Answer: B. Oxygen attracts electrons more strongly
Explanation: Oxygen is more electronegative, creating
partial charges that make water polar.


5. pH measures:


A. Oxygen concentration
B. Hydrogen ion concentration
C. Carbon levels

, D. Temperature


Answer: B. Hydrogen ion concentration
Explanation: pH indicates acidity or alkalinity based on
hydrogen ion concentration.


6. Buffers function to:


A. Increase pH rapidly
B. Stabilize pH
C. Remove acids
D. Neutralize water


Answer: B. Stabilize pH
Explanation: Buffers resist sudden pH changes, crucial for
maintaining homeostasis.


7. Which element is most abundant in living organisms?


A. Carbon
B. Hydrogen
