Reading

1. Which additional information would be MOST helpful in further understanding the issue of microplastics?

Correct answer: B

Rationale: Understanding the specific microbes used in bioremediation would directly contribute to knowledge about the solution proposed in the passage.

2. The epiglottis is a small flap of cartilage located near the base of the tongue. What is its role during swallowing?

Correct answer: C

Rationale: The epiglottis is a crucial anatomical structure that covers the trachea during swallowing to prevent food aspiration. When we swallow, the epiglottis folds over the trachea, directing food and liquids down the esophagus instead of entering the airway. This action helps to ensure that the food and liquids go to the stomach for digestion and not into the lungs, which can lead to aspiration pneumonia, a serious condition. Therefore, option C, 'Covers the trachea to prevent food aspiration,' is the correct role of the epiglottis during swallowing.

3. Which statement accurately describes the Linnaean system of classification?

Correct answer: D

Rationale: Rationale: The Linnaean system of classification, developed by Carl Linnaeus, is based on a hierarchical ranking system where organisms are grouped into categories based on shared characteristics. This system organizes organisms into a hierarchy of increasingly specific categories, from broad to narrow, such as kingdom, phylum, class, order, family, genus, and species. This hierarchical approach allows for the systematic organization and classification of a wide variety of organisms based on their similarities and differences.

4. What is the shape of the DNA molecule?

Correct answer: C

Rationale: Rationale: The shape of the DNA molecule is a double helix. This structure was first described by James Watson and Francis Crick in 1953. The double helix shape consists of two strands that are twisted around each other in a spiral. This shape allows DNA to be compactly stored within the cell nucleus and provides stability to the molecule. The other options (A) Linear, (B) Circular, and (D) Straight chain do not accurately describe the shape of the DNA molecule.

5. What is the main function of the epiglottis, a small flap of cartilage located above the larynx?

Correct answer: B

Rationale: The correct answer is B: 'To control the passage of food and air.' The epiglottis is a crucial structure that prevents food and liquids from entering the airway during swallowing. It acts as a lid over the trachea, ensuring that food goes down the esophagus while air passes into the respiratory system. This function is essential for preventing choking and ensuring proper breathing. Options A, C, and D are incorrect as the epiglottis is not primarily responsible for warming and humidifying inhaled air, producing sound vibrations for speech, or sensing foreign objects.

6. Which of the following is an example of a polymer?

Correct answer: C

Rationale: Polyethylene is a polymer, consisting of a large number of repeating ethylene units. The other choices represent small organic compounds.
