Parasites benefit their hosts is the true statement. Parasitism is a symbiotic relationship in which one organism (the parasite) benefits from another organism and this other organism is harmed by the parasite.
The others aren't true because:
- the organism that is harmed doesn'y adapt and evolve it still is vulnerable
- it is a fact that parasites change from hosts
- phoresy is an association between two species in which one transports the other. This does not include killing the host (is possible, but it is not a condition under which you can call something a phoresy).
The answer is "Vacuole". I hope this help!
Limited installation sites best describes a drawback in the scientists' plan because tidal energy is not present everywhere.
<h3>
Describes a drawback in the scientists' plan?</h3>
The big disadvantage of tidal power is that there are limited installation sites for it. It is expensive as well as the turbines can adversely impact the surrounding ecosystem.
So we can conclude that limited installation sites best describes a drawback in the scientists' plan because tidal energy is not present everywhere.
