Hey scientist wonders what would happen if all the trees in the amazon rainforest were cut down. which of the following is the most ethical reasons for running a simulation rather than cutting down all the trees in the rainforest?
a. there would be no place to dispose of the trees once they were cut down
b. the natural world should be disturbed as little as possible in an experiment
c. travel to and from the amazon might be too expensive for a scientist
d. it might be too expensive to buy enough chainsaws for the experiment

B. The natural world should be disturbed as little as possible in an experiment

Explanation:

In doing any type of experiment that includes the natural world, the best and most ethical way to do it is to make as little disturbance to it as possible. The reasons for this are many. One of them is that if the experiment creates big disturbance to the natural world, it will create lot of damage to it, with many species becoming endangered or extinct. Also, the natural world is needed, both for the humans and for having proper living conditions for the other organisms. The ethical part also plays big role, as to perform an experiment with the cost of harming millions of organisms is very cruel and irresponsible, plus there's not a single positive in it.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

there really is life in the deepest part
