Answer and Explanation

The Correct Answer is C

A. Connective: Connective tissue provides support and structure (e.g., tendons, cartilage) but is not muscle tissue.

B. Cardiac: Cardiac muscle, found in the heart, is involuntary and contracts rhythmically without conscious control.

C. Skeletal: Skeletal muscle is the only voluntary muscle tissue, meaning it is consciously controlled. It allows movement of the body by attaching to bones via tendons.

D. Smooth: Smooth muscle, found in internal organs (e.g., intestines, blood vessels), is involuntary and controlled by the autonomic nervous system.

A. Are found primarily in the axillary and genital areas: Apocrine glands are sweat glands located in the armpits (axillary) and genital regions. They become active at puberty and secrete a thicker sweat that can cause body odor.

B. Are endocrine glands: Apocrine glands are exocrine glands, not endocrine. They release their secretions onto the skin surface through ducts rather than into the bloodstream.

C. Arise within the hypodermis: Apocrine glands are located in the dermis, not the hypodermis. The hypodermis consists mostly of fat.

D. Are called oil glands: Oil glands (sebaceous glands) produce sebum, while apocrine glands secrete sweat.

Correct Answer is B

Explanation

A. Appear yellow: Yellow skin is often due to jaundice (bilirubin accumulation) or carotene deposits, not keratinization.

B. Are hardened and water-resistant: Keratinization involves the production of keratin, making the epidermis tough and water-resistant to protect against dehydration and external damage.

C. Appear cyanotic: Cyanosis is a bluish discoloration due to hypoxia, not keratinization.

D. Have been replaced by connective tissue: Keratinized epidermal cells are still part of the skin, whereas connective tissue replacement occurs in scarring or wound healing.
