Nail Facts and Vocabulary Quiz

Awry means crooked, off course, or not going as planned - something that has gone wrong or is askew. Option C 'straight' is the direct antonym. Option A 'original' and option B 'beneficent' are unrelated. Option D 'nonpoisonous' is also unrelated - awry has nothing to do with toxicity. The question correctly identifies 'straight' as the opposite.

Belittle means to make someone or something seem smaller or less important - to diminish or disparage. Option D 'magnify' means to make larger or exaggerate, which is the direct antonym. Option A 'small' is an adjective describing size, not an antonym for the verb. Option B 'large' and option C 'blessing' are unrelated. The question correctly identifies magnify as the opposite.

Men's fingernails generally grow faster than women's fingernails due to hormonal differences, particularly higher testosterone levels which stimulates nail growth. The average growth rate is about 3 mm per month for men versus slightly less for women.

Fingernails grow faster than toenails on average due to better blood circulation and higher exposure to growth-stimulating factors. Fingernails grow about 3 mm per month while toenails grow only about 1 mm per month, making fingernails approximately three times faster.

Nails are made of keratin, a protein that can be dissolved by acids. Since Coke contains phosphoric and citric acids with a pH around 2.5, it can gradually break down the keratin structure over time. This is why prolonged exposure to acidic beverages can weaken nails.

Nails are primarily composed of keratin, a tough fibrous protein that also makes up hair and the outer layer of skin. This protein provides nails with their strength and protective qualities. Keratin requires proper nutrition including proteins, vitamins, and minerals for healthy formation.

Nail beds and cuticles are composed of living tissue that requires oxygen, vitamins, and minerals for healthy nail growth. The living cells in the nail matrix and nail bed are actively producing keratin cells that form the nail plate. Adequate blood supply delivers nutrients essential for nail health.

Toe nails are approximately twice as thick as fingernails, not five times. This thickness difference is evolutionary - toes need more protection due to greater pressure and friction from walking. The average toenail is about 1-1.5 mm thick while fingernails are about 0.5-0.75 mm thick.

Nail growth rates are not equal between young and old people. Growth is fastest in childhood and adolescence, peaks in early adulthood, then gradually declines with age. Older adults typically experience slower nail growth due to reduced circulation, hormonal changes, and decreased cell turnover rates.

During pregnancy, hormonal changes (especially increased estrogen) and improved blood circulation accelerate nail and hair growth. This is a well-documented physiological response to pregnancy.

Hair and nails cannot grow after death because growth requires glucose, oxygen, and nervous system regulation - all of which cease at death. The illusion of growth comes from skin dehydration and retraction.

Fingernails grow approximately 0.1 mm per day (about 3 mm per month, or 1 inch per year). The rate of 0.1 mm in 100 days would be barely visible.
