As a person ages, the body is less able to metabolize glucose efficiently, which results in which condition?

A. Scars from a severe burn: Although burn scars may increase skin sensitivity and vulnerability, they are not a primary cause of skin cancer.

B. Exposure to environmental pollutants: Some pollutants may contribute to skin damage, but UV radiation is the primary cause of skin cancer.

C. History of viral illness: Some viruses, such as HPV, are linked to specific cancers (e.g., cervical cancer), but they are not a primary cause of skin cancer.

D. Sun exposure: UV radiation from the sun is the most significant risk factor for skin cancer, particularly basal cell carcinoma, squamous cell carcinoma, and melanoma.

A. Connective tissue: Connective tissue has an extensive and varied extracellular matrix, which includes collagen, elastin, and ground substance. This allows it to provide support, cushioning, and structure to the body.

B. Simple squamous epithelial: Simple squamous epithelium is a single layer of flat cells with minimal extracellular matrix, mainly involved in diffusion and filtration.

C. Stratified squamous epithelial: Stratified squamous epithelium consists of multiple layers of cells but has very little extracellular matrix, as it primarily functions in protection.

D. Cuboidal epithelial: Cuboidal epithelial tissue, like other epithelial types, has tightly packed cells with minimal extracellular matrix, mainly functioning in secretion and absorption.
