Explanation:
Helminths are the parasites with a worm-like body structure and include the flatworms, tapeworms, and nematodes.
Trematode flatworms are the flatworms that cause the disease schistosomiasis. The schistosomiasis parasite is spread when freshwater snail releases its larva in the water bodies which in turn enter the healthy person bathing in the water.

2. The tall neck Giraffes reproduced and their off spring inherited their genes
3. A drought occurred.
Explanation:
Answer:
Temperatures gradient
Explanation:
There are distinct temperature gradient differences in the layers of atmosphere usually due to the main air molecule composition of the layers, the density of the molecules. The Troposphere the lowest layers is the densest and temperature decreases with increase in altitude. The stratosphere, on the other hand, has an increase in temperature with increase in altitude. Temperatures decrease with altitude in the mesosphere while the parameter increases with altitude in the thermosphere.
The nervous system communicates through electrical impulses and the communication is very fast. It works in a relay fashion, from point to point comparable to the way the old telephones systems used to work.
The endocrine system communicates by chemical signals via the bloodstream. Hormones are secreted into the blood and extra cellular fluids, then transported to target cells, which must bear a receptor to be able to bind to a specific hormone, and respond.
Hormones are chemical messengers secreted into blood or extracellular fluid that affect the function of other cells.
Endocrine communication is not quite as fast as the nervous system communication
Those are examples of ecosystem services! Hope this helps:)
