Which of the following is a negative consequence of commercial fishing? a) improved water quality b) an increase in human fatalities c) improved nutritional value of fish d) an increase in biodiversity

Option (B) is the correct answer.

Explanation:

When people catch fish or other sea food in order to commercially sell them then this kind of activity is known as commercial fishing.

So, people who earn their livelihood by selling fishes or other sea food animals have to go under water in adverse conditions and thus, they put their life at risk just to earn their bread.

This leads to an increase in human fatalities.

Thus, we can conclude that an increase in human fatalities is a negative consequence of commercial fishing.

B) An increase in human fatalities

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.

i'd say that the moon rock is about 2.2 billion years old.
