Biology

1. What is the difference between a phylum and a class?

Correct answer: A

Rationale: Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. Phylum is a broader category that includes multiple classes within it. Phylum represents a group of organisms sharing a common body plan or evolutionary history, while a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phylums are broader and more general compared to classes.

2. What checkpoint mechanism ensures all chromosomes are attached to the spindle fibers before anaphase begins?

Correct answer: A

Rationale: Rationale: A) Prometaphase is the correct answer because it is the stage of mitosis where all chromosomes are attached to the spindle fibers before anaphase begins. During prometaphase, the nuclear envelope breaks down, allowing the spindle fibers to attach to the kinetochores of the chromosomes. This attachment is necessary for proper chromosome alignment and segregation during anaphase. B) Metaphase is incorrect because it is the stage where chromosomes are aligned at the metaphase plate but do not necessarily have all spindle fibers attached. C) Cyclin degradation is incorrect because it is a regulatory mechanism that controls the progression of the cell cycle but is not specifically related to ensuring all chromosomes are attached to spindle fibers. D) Sister chromatid cohesion is incorrect because it refers to the physical connection between sister chromatids that is maintained until anaphase, but it does not ensure that all chromosomes are attached to spindle fibers.

Correct answer: B

Rationale: The emphasis on balancing benefits and risks suggests a cautious and balanced perspective, aligning with B.

4. After exposure to a pathogen, the immune system develops memory. What type of immune cell is responsible for this immunological memory?

Correct answer: B

Rationale: The correct answer is A: "B cells." B cells are responsible for generating immunological memory after exposure to a pathogen. When B cells encounter a pathogen, they differentiate into memory B cells, which can quickly recognize and respond to the pathogen upon subsequent exposure. These memory B cells are crucial for mounting a faster and more effective immune response, leading to a quicker clearance of the pathogen. T cells, phagocytes, and natural killer cells play important roles in the immune response, but specifically, memory B cells are responsible for immunological memory.

5. What is the scientific term for the windpipe, a tube that carries air from the larynx to the bronchi?

Correct answer: B

Rationale: The correct answer is B: Trachea. The trachea is the scientific term for the windpipe, which is a tube that carries air from the larynx to the bronchi. The pharynx is the throat area where the mouth and nasal passages meet. The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food from entering the airway. Bronchioles are smaller airway branches in the lungs. Therefore, the trachea best fits the description of a tube carrying air from the larynx to the bronchi.

6. Which state of matter has a definite shape and volume but can flow?

Correct answer: B

Rationale: Liquids have a definite volume but can take the shape of their container, unlike solids with fixed shapes and volumes.
