Sample Questions from the 2013 Living Environment Regents Exam

Below are representative sample questions that reflect the types of items students encountered in the 2013 exam.

Multiple Choice Sample Question

Question:

Which of the following best explains why a cell’s membrane is considered semi-permeable?

A) It allows all substances to pass freely.

B) It blocks all substances from entering or leaving the cell.

C) It permits some substances to pass while blocking others.

D) It only allows water to pass through.

Answer: C) It permits some substances to pass while blocking others.

Short Answer Sample Question

Question:

Describe the role of the nucleus in a eukaryotic cell. Include in your answer the types of molecules it contains and their functions.

Sample Response:

The nucleus acts as the control center of a eukaryotic cell. It contains the cell’s DNA, which carries genetic information necessary for cell activities and reproduction. The nucleus also contains nucleolus, where ribosomes are assembled. Its primary functions include regulating gene expression, controlling cell growth, and coordinating cell division.

Extended Response Sample Question

Question:

Explain how natural selection can lead to the evolution of a species. Use an example to support your explanation.

Sample Response:

Natural selection leads to evolution when individuals with advantageous traits are more likely to survive and reproduce, passing those traits to their offspring. Over generations, these traits become more common in the population. For example, in a population of birds, if some have beaks better suited for cracking hard seeds, those birds are more likely to survive during food shortages. Their offspring inherit the stronger beak trait, and over time, the species’ beak morphology may evolve to be larger and stronger.

Key Tips for Success on the Living Environment Regents Exam 2013

• Review all major topics thoroughly: Focus on understanding concepts rather than rote memorization.
• Practice with old exams and sample questions: This helps become familiar with question formats and timing.
• Use diagrams effectively: Be prepared to interpret and draw biological diagrams, such as the structure of a cell or a DNA molecule.
• Understand experimental procedures: Be able to identify variables, controls, and interpret data presented in tables or graphs.
• Stay calm and manage your time: Allocate appropriate time for each section and question.

Conclusion: Mastering the Living Environment Regents Exam 2013
