Being a woman myself, the answer is the Fallopian tubes.
<span>The cortex is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex.

The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.
Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.
These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)
The answer is increased mutation rate.
Reproductive isolation is the existence of biological factors that impede members of two species from interbreeding and producing viable fertile offspring. These biological barriers may be pre-zygotic or post zygotic; post zygotic barriers include developmental errors of embryo, become infertile, or not living long enough to reproduce; while the prezygotic barriers include; habitat isolation, temporal isolation, genetic barriers among others.
