Answer:
Scientists mostly gain new knowledge through direct observation and applying the scientific method. They would start with a hypothesis and test it, then change it or confirm it. Others would test their confirmation from one point, while the third group would test what the second said. And so on and so forth.
Explanation:
The correct answer is answer choice A, 'In predation the predator usually kills its prey, whereas in parasitism the parasite does not usually kill its host'. While parasites can occasionally kill their hosts, it is more beneficial for the parasite to keep its host alive so that it can continue surviving off of the nutrients it gathers. Answer choice B is incorrect because the prey in predator-prey relationships and the host in parasitism do not benefit. Answer choice C is incorrect because the host does not benefit in parasitism, and is often harmed by the parasite. Answer choice D is incorrect because a predator usually kills its prey, while a parasite usually does not kill its host.
Hope this helps!
