Q1. Which one of the following is a TRUE statement about cells?
Background
Topic: Cell Theory and Characteristics of Life
This question tests your understanding of the basic principles of cell theory and what distinguishes living things from nonliving matter.
Key Terms and Concepts:
Cell Theory: All living things are made up of cells; the cell is the basic unit of life; all cells come from pre-existing cells.
Homeostasis: The ability of an organism to maintain a stable internal environment.
Step-by-Step Guidance
Review the statements and recall the three main tenets of cell theory.
Eliminate any options that contradict what you know about cells and living organisms.
Focus on the statement that best summarizes a universal property of all living things.
Consider why the other statements are incorrect or incomplete based on your knowledge of biology.

Q2. A properly designed controlled experiment should include both an ______ group, where a variable is manipulated, and a(n) ______ group, where no variables are manipulated.
Background
Topic: Scientific Method and Experimental Design
This question tests your understanding of how to set up a controlled experiment, including the roles of experimental and control groups.
Key Terms and Concepts:
Experimental Group: The group in which the variable of interest is changed or manipulated.
Control Group: The group that does not receive the experimental treatment and is used as a baseline for comparison.
Step-by-Step Guidance
Recall the definitions of experimental and control groups in the context of scientific experiments.
Think about why it is important to have both groups in an experiment.
Match the correct terms to the blanks in the question based on their definitions.

Q3. What happens when the outermost phosphate is removed from an ATP molecule?
Background
Topic: Cellular Energy and ATP
This question tests your understanding of how ATP (adenosine triphosphate) provides energy for cellular processes.
Key Terms and Concepts:
ATP: The main energy currency of the cell.
Phosphate Group Removal: The process of hydrolyzing ATP to ADP releases energy.
Step-by-Step Guidance
Recall what ATP stands for and its role in the cell.
Think about what happens chemically when a phosphate group is removed from ATP.
Consider the consequences of this reaction for cellular work and energy transfer.

Q4. Body fluids in humans have a high buffering capacity because of what?
Background
Topic: Acid-Base Balance and Buffers
This question tests your understanding of how the body maintains pH homeostasis, especially the role of buffer systems.
Key Terms and Concepts:
Buffer System: A solution that resists changes in pH when acids or bases are added.
Bicarbonate/Carbonic Acid System: The primary buffer system in human blood.
Step-by-Step Guidance
Recall what a buffer is and why it is important in biological systems.
Identify the main buffer system in human blood.
Consider how this system helps maintain a stable pH in the body.

Q5. Which of the following is needed to synthesize a new strand of DNA?
Background
Topic: DNA Structure and Replication
This question tests your knowledge of the building blocks required for DNA synthesis.
Key Terms and Concepts:
Nucleotides: The monomers that make up DNA and RNA.
DNA Replication: The process by which a cell copies its DNA before cell division.
Step-by-Step Guidance
Recall the structure of DNA and what it is composed of.
Identify the molecules that serve as the building blocks for new DNA strands.
Eliminate options that are not directly involved in DNA synthesis.
