2. What is the main point of the passage?

3. During embryonic development, all tissues originate from

Correct answer: D

Rationale: During embryonic development, all tissues originate from the three primary embryonic germ layers: ectoderm, mesoderm, and endoderm. These layers give rise to all the different types of tissues found in the body. The ectoderm forms the skin and nervous system, the mesoderm gives rise to muscle, bone, and connective tissues, while the endoderm develops into the lining of the digestive and respiratory systems. Therefore, option D is the correct answer as it encompasses the comprehensive origin of all tissues in the body during embryonic development.

4. How are genetic markers used in paternity testing?

Correct answer: B

Rationale: Rationale: Genetic markers are specific DNA sequences that can vary among individuals. In paternity testing, genetic markers are used to compare the DNA of the child with that of the alleged father. By analyzing the presence or absence of specific alleles (different forms of a gene) at these genetic markers, scientists can determine the likelihood of paternity. This method is more accurate and reliable than comparing blood types or physical resemblance, making option B the most appropriate choice.

5. What is the main difference between a telescope and a microscope?

Correct answer: A

Rationale: While both instruments magnify objects, telescopes are designed to observe distant objects, while microscopes are used to magnify tiny objects close to the observer.

6. Identify the participial phrase in the following sentence: "Running through the park, she spotted a squirrel."
