Flatworm Love and Hates Its Mate

The marine flatworm is a hermaphrodite – each has both male and female sex organs. When it has the urge to reproduce, an exceptional sense of smell is used to track a mate from long distances. When they finally join, they are extremely hostile. The two would-be lovers rear up immediately, like two swordsmen at the ready, revealing sharp, double-headed organs. This tool, also used for hunting food, serves the purpose of stabbing the other violently with genetic material. The scientific community refers to this activity as "penis fencing", and it can last up to 20 hours.

When we meet people who are so much like ourselves, we can confuse commonalities with compatibility. The desire to be with someone can be a reason to stay. It is easy to overlook tiny disagreements – about decorating the flat, for example, or where to eat.

For marine flatworms, an extended stay with an unfriendly mate results in their bodies being ravaged with holes. Afterwards both worms go off alone. The loser lost a game of "traumatic insemination", and if you hadn't guessed, her female self will later endure the costly undertaking of bearing children. Alone, torn and pregnant, she must wonder if it was worthwhile.decides fighting with someone is better than fighting with no one.

Isotonic Drink Recipe

Isotonic drinks aim at keeping electrolytic balance on the body after doing hard activity like sport, replacing an electrolytes lost through sweat, and providing energy from carbohydrates. Isotonic drink have close osmolarity to the human body, the density of drink should be close to the blood plasma in order to facilitate the blood absorption. Concentrate drink like sweet juice will make dehydration because the body will secrete water to absorb it. Too sparse drink like clean water have paradoxically lead to the same situation.

We can prepare by our self of isotonic drink by mixed of tea or fruit juice (for flavor), sugar, and for long duration efforts, maltodextrin. To use maltodextrines should follow the instruction as on the guideline on this supplement.
