What must happen for sexual reproduction to take place in a flatworm?

In flatworms, sexual reproduction occurs when two individuals mate and exchange sperm. This can happen through hypodermic insemination, where the male stabs the female with a needle-like copulatory organ to transfer the sperm. The sperm then fertilizes the eggs inside the female's body.

What can cause sharp intense pain in the forehead which only lasts a few seconds?

A sharp, stabbing pain that occurs as a single or short series of stabs can be what is called an ice pick headache. These are often called a Primary Stabbing Headache. They are most common in people who have cluster or migraine headaches, and are very common in women. Treatment can be difficult due to the short duration of pain. Using an ice pack can help a headache, as well as over the counter pain relievers. If the become a big problem your doctor can prescribe various medications to try.

Small sharp stabbing weapon?

The assassin weapon of choice for years that was small, easy to push in deep even for a weak woman, and easy to pull back out too, was an ice pick. They are rare to find today but they are strong enough to puncture bone and reach the brain or heart easily. The ice pick is built to rip apart large blocks of ice and is a very strong long spiked weapon capable of even penetrating body armor. The one drawback is that it makes a small hole so the person using it must be accurate in their attack or the person stabbed could live long enough to attack back. It is best for heart and brain stabs or if the attacker knows anatomy, major arteries or veins in the neck, arm, groin etc.
