Question

why is the keratinocyte no longer viable in the stratum lucidum? a) the cell is too far away from the source of nutrients b) the cells membrane is too thick for nutrients to pass through c) the cell is too full of keratin to fit organelles as well d) the cell is too far to be protected by the immune system

Explanation:

In the stratum lucidum, keratinocytes become non - viable mainly because they are too far from the blood supply (source of nutrients) in the dermis. As cells move up through the skin layers, they get further from the nutrient source and eventually die. The other options are not the primary reasons for non - viability in the stratum lucidum.

Answer:

A. The cell is too far away from the source of nutrients
