Because skin is a protective layer covering all the internal viscera including lungs and breasts. Skin cells as they are in direct exposure to outer environment are prone to some cuts, injuries, wounds etc. Hence the skin cells are required to repair the tissues as soon as possible. On the other hand, lung cells or breast cells don't require to grow once they attain certain age normally so the cells remain in Quiescent stage (Qo).
Hence skin cells have to have higher mitotic index
Add Answer to:
Why does a normal skin cell have a higher mitotic index compared to normal breast and...

In a recent study, the expression profiles for 6900 genes in normal and malignant breast tissues from rats were compared. RNA was extracted using the following tissues: a. breast tissue from virgin rats b. breast tissue from pregnant rats c. breast tissue from lactating rats d. breast carcinomas induced by the meat-derived carcinogen, PhIP e. breast carcinomas induced by the experimental carcinogen, DMBA Tissues a, b, c were grouped together as normal and tissues d, e were grouped as carcinoma...

Cancer cells often lack normal DNA damage response and cell-cycle control mechanisms. Why does this make them more susceptible to DNA-damaging chemotherapies? O Cancer cells will arrest in the cycle and will not grow further O Cancer cells with activating mutations in Ras will amplify the damage through the Ras signaling pathway Cancer cells might ignore the normal mechanisms that halt the cell cycle in response to damage, and subsequent division with damage leads to death, O Cancer cells have...

transformed eukaryotic cells utilize glucose at a higher rater than normal cells. you have isolated two transformed cell lines (a and b) and incubate cell homogenates with glucose labeled with C14 in the 1,3,4, or 6 positions to measure the initial rates of the radioactive labeled CO2 production. If cell line A metabolizes glucose primarily by the HMP shunt, and cell line B metabolizes glucose primarily by glycolysis, what will be the pattern of the radimetrically labeled CO2 formation from...

Why does benzene have a much higher boiling point (80。c) than hexane (69。c), even though they have the same number of carbons? A) Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point. B) Benzene has fewer hydrogens than hexane. C) Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point. D) Benzene can covalently bond to another benzene molecule which...
