1. The fundamental units of structure and function in all living organisms, including humans, are termed:

• A. Muscles
• B. Organs
• C. Tissues
• D. Cells

Correct answer: D

Rationale: The correct answer is D: Cells. Cells are the fundamental units of structure and function in all living organisms, including humans. They are the building blocks of life, performing various functions necessary for an organism to survive and thrive. Muscles (A) are composed of muscle tissue, which is made up of muscle cells. Organs (B) are structures made up of different types of tissues working together. Tissues (C) are groups of cells that work together to perform specific functions within an organism. However, cells are the smallest unit of life and are responsible for carrying out all the essential processes needed for an organism to function.

2. Which element has the lowest electronegativity value?

• A. Oxygen
• B. Fluorine
• C. Helium
• D. Chlorine

Correct answer: C

Rationale: Electronegativity is the tendency of an atom to attract electrons towards itself in a bond. Noble gases like helium have very low electronegativity because their outer electron shell is already full and stable.

3. What is the term for the reaction between an acid and a base to produce water and a salt?

• A. Combustion
• B. Neutralization
• C. Oxidation
• D. Decomposition

Correct answer: b

Rationale: Neutralization is the reaction between an acid and a base to produce water and a salt. The other choices do not accurately describe neutralization.

4. In the reaction 2H2 + O2 → 2H2O, how many moles of oxygen are required to react completely with 4 moles of hydrogen?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: 2

Rationale: The balanced equation indicates a 1:1 ratio between H2 and O2, so 4 moles of H2 require 4 moles of O2, and 2 moles of H2 require 2 moles of O2.

5. Which word is spelled correctly?

• A. Accomodate
• B. Acquiesce

• C. It is less effective than traditional methods and poses environmental risks.
• D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.
