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 cholecystokinin generates a satiety or nausea sensation to the brain, quenching the appetite once it has eaten enough, occurs naturally in the human organism in the small intestine, secreted from the cells of the duodenum and jejunum to promotes fats absorption in the digestion process.
All that is slow gastric emptying.
True. They have tools to do so.
I hope i helped!
Shivering occurs when the core temperature of the body begins to decrease which would threaten normal body function. Shivering is a response by the body to bring back temperature back to homeostasis. Trembling is the continual involuntary contraction of muscles. Muscle activity releases heat that warms up the body. This is the reason why we sweat during physical activities as the body sheds excess heat generated by the muscles in order to maintain the homeostatic body temperatures of 37 degrees centigrade.
The answer is: o less likely to survive and less likely to reproduce
