Why does sub-par mean bad when under par in golf is good? You make a good point, it is a strange one. But in this context par is meant to mean, the average, of the usual quality etc, so below par essentially means sub standard, and h â¦ as nothing to do with golf.
Tapeworms lack a mouth and a digestive tract. Describe the tapeworms. They are segmented, flat, have no digestive system, and absorb all nutrients through the tegument (no mouth).
Humans are the only hosts for these Taenia tapeworms. Humans pass the tapeworm segments and/or eggs in feces and contaminate the soil in areas where sanitation is poor. Taenia eggs can survive in a moist environment and remain infective for days to months.Cows and pigs become infected after feeding in areas that are contaminated with Taenia eggs from human feces.atients with T. saginata taeniasis often experience more symptoms that those with T. solium because the T. saginata tapeworm is larger in size (up to 10 meters (m)) than T. solium (usually 3 m). Tapeworms can cause digestive problems including abdominal pain, loss of appetite, weight loss, and upset stomach.
