__________ makes up the intervertebral disc; whereas, __________ makes up the costal cartilage between the ribs and sternum
Fibrocartilage; hyaline cartilage
Dense regular CT; fibrocartilage
Hyaline cartilage; fibrocartilage
Fibrocartilage; dense regular CT
Elastic cartilage; hyaline cartilage
The Correct Answer is A
A. Fibrocartilage; hyaline cartilage: Fibrocartilage is found in intervertebral discs, providing strong support and resistance to compression due to its dense collagen fibers. Hyaline cartilage forms the costal cartilage between ribs and the sternum, offering flexibility and smooth surfaces for joint movement.
B. Dense regular CT; fibrocartilage: Dense regular connective tissue is found in tendons and ligaments, not in intervertebral discs. Fibrocartilage, while present in discs, is not the main component of costal cartilage.
C. Hyaline cartilage; fibrocartilage: Hyaline cartilage provides structural support and smooth surfaces, but it is not the primary tissue of intervertebral discs. Fibrocartilage is not the main tissue of costal cartilage.
D. Fibrocartilage; dense regular CT: Dense regular connective tissue does not make up costal cartilage; it is primarily in tendons and ligaments. Fibrocartilage correctly describes intervertebral discs.
E. Elastic cartilage; hyaline cartilage: Elastic cartilage is found in structures requiring flexibility, such as the ear and epiglottis, not intervertebral discs. Hyaline cartilage correctly describes costal cartilage, but the first part is inaccurate.

Correct Answer is D
Explanation
A. late prophase:During late prophase, chromosomes condense and the mitotic spindle forms, but cytokinesis has not yet begun as the cell is still preparing for chromosome alignment.
B. early anaphase:Early anaphase involves the separation of sister chromatids toward opposite poles. Cytokinesis does not start at this point because chromosome separation is still in progress.
C. early prophase:Early prophase is the initial stage of mitosis where chromatin condenses into visible chromosomes. Cytokinesis is not initiated at this stage.
D. late anaphase:Cytokinesis begins during late anaphase, when the cell starts forming a cleavage furrow as the chromosomes near the poles. This process continues into telophase, ultimately dividing the cytoplasm into two daughter cells.
Correct Answer is A
Explanation
A. mesothelium:Mesothelium is a specialized simple squamous epithelium that lines the serous membranes of body cavities, including the peritoneum, pleura, and pericardium. It provides a smooth, friction-reducing surface and facilitates the movement of organs within these cavities.
B. hyaline epithelium:Hyaline epithelium is not a recognized tissue type. Hyaline typically refers to cartilage, not epithelial tissue, and does not line serous membranes.
C. areolar CT:Areolar connective tissue is a loose connective tissue that supports and cushions organs, but it is not an epithelial layer and does not form the lining of serous membranes.
D. endothelium:Endothelium is a simple squamous epithelium that lines blood vessels and the heart, not serous cavities. It functions primarily in exchange of materials and maintaining vascular homeostasis.
