Can flatworms and roundworm be harmful to humans and other animals?
Flatworms are typically asymptomatic. This can prevent the tapeworm ever being detected until it eventually dies and is passed out of the body through the stool. Occasionally human hosts experience nausea or abdominal cramps when infected with flatworms. A roundworm infection can cause more serious symptoms such as headaches and severe pain, depending on the worm's location within the body. In severe cases, roundworms have been known to cause blindness or paralysis.

The conversion between international units (IU) and grams (gm) depends on the substance being measured, as different substances have different conversion factors. For example, 1 IU of vitamin D is approximately 0.025 micrograms (mcg), while 1 IU of insulin is around 0.0347 mg. To convert 1,000,000 IU to grams for a specific substance, you would need to know the specific conversion factor for that substance.

Balestra. It is not really a jump in place, for the body should cover some forward distance, even more than the lunge that follows. When the balestra is executed correctly, the body does not hop up in the air(wasted movement) but springs forward in a way that looks like a regular lunge to the opponent. But instead of the trailing leg staying back, it is immediately brought up together with the lead foot. If the opponent has evaded this first attack, he might not be ready for the lunge that immediately follows.
