Yes, Schistosoma haematobium, the causative agent of urinary schistosomiasis, requires a secondary host, specifically freshwater snails of the genus Bulinus, to complete its life cycle. The adult worms reside in the human host's blood vessels, where they produce eggs that are excreted in urine. When these eggs reach freshwater, they hatch and infect the snails, where they develop into cercariae, which can then infect humans. Thus, both human and snail hosts are essential for the parasite's lifecycle.
Yes, schistosomiasis has an intermediate host, which is typically a type of freshwater snail. The larvae of the Schistosoma parasites develop within these snails before being released into the water, where they can infect humans. The infection occurs when people come into contact with contaminated water, leading to the transmission of the disease.
Definitive host (DH). A definitive host is an organism that hosts the adult (sexual) form of the parasiteIntermediate host (IH). An intermediate host is an organism that hosts the asexual form of the parasite (only when there is an obligatory passage through the host). Intermediate hosts can be divided into two groups:Passive IH (molluscs in the case of Schistosoma)Active IH (tsetse fly in the case of trypanosomes)Source: http://www.icp.ucl.ac.be/~opperd/parasites/types3.htm
The parasitic worm Schistosoma mansoni causes schistosomiasis in humans. The parasite's eggs can cause damage to the liver, intestines, bladder, and other organs, leading to symptoms such as abdominal pain, diarrhea, and blood in the urine.
No, blood flukes are not autotrophic. They are parasitic flatworms belonging to the genus Schistosoma and obtain their nutrients by feeding on the blood and tissues of their host organisms. Unlike autotrophic organisms, which produce their own food through processes like photosynthesis, blood flukes rely on their hosts for sustenance.

Because the host connects to the server to host the game while the other players connect to the host. That way it doesn't bog down the servers.
Picture the host as the viruses brain and heart.. Once the virus leaves the host it dies. In other words the host gives it life.
Minimum time a host must transmit for before it can be sure that no other host's packet has collided with its transmission. If the maximum propagation delay from one host to any other is T, then a host that starts to transmit at time t0 may collide with a host that starts just before t0 + T. The first host will not detect the collision until time t0 + 2T.

The answer to this question is a host! A host could be a host cell which a virus uses to reproduce and create more viruses to get you sick!
