How often do human skin cells divide? why might that be? compare this rate to how frequently human neurons divide. what do you notice?

explained

Explanation:

The skin cells divide every day, as the epithelial layer is the outer protective layer, it needs to be replaced from time to time, which helps in healing wear and tear. Our skin cells divide once in each day.

In contrast, the nerve cells do not divide at all. That is their frequency of cell division is zero. They cannot divide because they lack centriole in them.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
