    1. The law of entropy states that the total entropy can not decrease. However, it permits for entropy to decrease localy, as long as the entire system entropy does not. In addition, to decrease the entropy, one must do work (spend energy).

    While the embryo's entropy decreases, this comes at the account of the surrounding, which needs to supply ...
