Parasite: Parasites are different from predators because parasites only take resources from one host, whereas predators eat many prey. A good example of this is the trematode parasite Schistosoma mansoni. An adult schistosome parasite lives inside of just one human host
Biological diversity is the variety of species in a given area. If a new species is added there are more species and therefore greater biological diversity and if one goes extinct there are less species and therefore less biological diversity.
Answer:
The options are
Complex
Identical
Inconsistent
Non-testable
The Answer is Identical
Explanation:
The groups of scientists in different parts of the world who are dating fossils found in a rock layer of the same geologic time period. The findings have to have some common characteristics which links it to being in the same geologic time period.
This however validates the fossils having to be identical to match those found in other parts of the world.
The answer is; Warm water moves to the east instead of to the west
Normally, when the waters in the Pacific warm up, the prevailing winds that blow from east to west drag the warm surface currents westwards and upwelling of cold currents occur at the west coast of South America. However, in El Nino, the Pacific ocean waters heat more than usual. The prevailing winds weaken and begin to blow predominantly towards the east. The warm currents are therefore dragged to the east and cause torrential rains in Western coast South Americas.
