Exam Analysis: Specific Questions and Answers
In this section, we will analyze some specific questions from the June 2015 Living Environment Regents Exam and provide the answers along with explanations for a better understanding.
Sample Questions and Answers
1. Question 12: Which of the following structures is found in both prokaryotic and eukaryotic cells?
- A) Nucleus
- B) Mitochondria
- C) Cell Membrane
- D) Chloroplast
Answer: C) Cell Membrane
Explanation: All cells, regardless of being prokaryotic or eukaryotic, possess a cell membrane that regulates what enters and exits the cell.
2. Question 25: In pea plants, tall plants (T) are dominant over short plants (t). If a heterozygous tall plant is crossed with a short plant, what fraction of the offspring will be expected to be short?
Answer: 50%
Explanation: The genotypes of the parents are Tt (heterozygous tall) and tt (short). The possible combinations are Tt and tt; hence, half of the offspring will be short.
3. Question 36: The process of natural selection involves which of the following?
- A) Genetic modification of individuals
- B) Differential survival and reproduction of individuals
- C) Random mating
- D) Environmental changes affecting all individuals equally
Answer: B) Differential survival and reproduction of individuals
Explanation: Natural selection occurs when individuals with favorable traits are more likely to survive and reproduce, thus passing on those traits to the next generation.
4. Question 47: Which of the following best describes a food web?
- A) A complex network of feeding relationships among various organisms
- B) A simple linear path of energy flow in an ecosystem
- C) A detailed list of all organisms in a specific habitat
- D) A direct line of predator-prey interactions
Answer: A) A complex network of feeding relationships among various organisms
Explanation: A food web illustrates the interconnected feeding relationships in an ecosystem, showcasing how energy flows through various organisms.
