Some viruses found on the ocean's surface can infect and kill plankton. How would this affect the fish population and human health? (3 points)

A:Plankton are high on the food chain, so there would be limited impact on the plankton population or
human health

B:The virus could kill the plankton population, leaving the fish with less competition, ultimately
increasing food supplies for humans.

C:The virus could kill the plankton population, leaving the fish with little or no food source, ultimately
taking a food source away from humans,

D:Plankton are low on the food chain, so there would be no impact on the plankton population or
human health in relation to the ocean environment.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
