The female ovum is chiefly the largest cell visible in the naked eye with the size of a pea, having a diameter of about a millimeter.

All babies are born with blue eyes. The color of a person eyes will depend on his genetic make-up. For instance, if your parents have blue eyes, then there is 100% probability, that you are born with blue eyes as well. During birth, most babies appear to have blue eyes. This is due to melanin pigmentation. Melanin often needs time shortly after birth to be fully stored or to be darkened by ultraviolet light exposure, which reveals the baby’s real eye color.

Every individual have spent half an hour as a single cell. All living creatures has to begin somewhere else, and believe me each of them whether the smallest or largest species have been a single cell organism for a short period of time after the egg and sperm cells united. They then begin dividing rapidly and forming an embryo.
Erection occurs more often in men. Most of them experience erection every hour and every one hour and a half during sleep. A person’s mind and body are more active when they are sleeping.
