The sloughing off of older cells from the surface of the skin is called

A. the sweat glands released their product, causing the hair to grow
Hair does not grow postmortem, and sweat gland activity ceases after death.

B. the skin retracted from the hair follicles
After death, the skin dehydrates and shrinks, which can cause the hair shaft to appear longer, giving the illusion that hair has grown, even though it hasn't.

C. during the process of decomposition, the hairs grew out of the follicles
Hair cannot grow after death because cellular metabolism and mitosis cease.

D. the skin grew out, forcing the hair out of the follicles
Skin does not grow postmortem; this is scientifically inaccurate.

A. osteoporosis
This is a condition of reduced bone mass, often due to calcium/Vitamin D deficiency or hormonal imbalance-not defective collagen.

B. osteogenesis imperfecta
Known as “brittle bone disease”, osteogenesis imperfecta is a genetic disorder caused by defective or insufficient type I collagen, leading to fragile bones.

C. osteomalacia
Caused by Vitamin D deficiency, leading to soft bones due to defective mineralization, not collagen defects.

D. osteoarthritis
Degeneration of articular cartilage due to aging or wear-and-tear, not a collagen production issue.

E. osteopetrosis
A bone resorption disorder due to defective osteoclasts, resulting in abnormally dense but brittle bones-not due to collagen abnormalities.

F. fibrodysplasia ossificans progressiva
A rare genetic disorder in which soft tissue gradually turns into bone, unrelated to collagen production.
