Trichinella worms sometimes cause the disease known as trichinosis in humans when undercooked pork is eaten. These organisms hav
e long cylindrical bodies but no segmentation. This species is MOST similar to which of the following animals?A. Nematodes.B. FlatwormsC. EarthwormsD. Jellyfish.E. None of the above are related to trichinella worms
Nematodes are a subdivision of the animal kingdom known as Nematoda. The group consists of round/cylindrical worms without body segments. They are mostly microscopic, bilaterally symmetrical with a wide range of habitat. Many of the species in this group are endo-parasites of man and other higher animals.
The flatworms belongs to the Platyhelminthes phylum. They are unsegmented and parasites of other animals just like nematodes. However, they are flat in shape as opposed to cylindrical shape of nematodes.
Earthworms belong to the phylum Annelida. They are segmented with nervous system.
In this case, the Trichinella worms seem to be most similar to Nematodes in that:
You can put wind energy propellers on the front of your car. This would be effective, as the high speed of the car would increase the rate of energy produced.
You could also have a metal rod slightly scraping the ground, and take the heat generated by friction to produce energy.
About 8.7 million (give or take 1.3 million) is the new, estimated total number of species on Earth -- the most precise calculation ever offered -- with 6.5 million species on land and 2.2 million in oceans.
Results in a decline in CD4+T cell numbers below the critical level, and loss of cell-mediated immunity. Therefore the body becomes progressively more susceptible to opportunistic infections and cancer.
