Amarine scientist observes that dissolved oxygen decreases with increasing ocean depth. he concludes that deep sea creatures must require less oxygen than those at shallower depths. why is this an invalid scientific conclusion? a.) he did not compare data in different oceans b.)more research is needed to reach a conclusion, including related variables c.)the data he collected was from a laboratory and not in natural conditions d.)the data he collected was relative and not absolute

B.) More research is needed to reach a conclusion, including related variables

Explanation:

As it is evident that oxygen is necessary element for living beings. It is required for the process of respiration, in which the food particles are broken down in the presence of oxygen into simpler substances.

Applying this knowledge to the given study suggests that all organisms require oxygen which can be less or more depending upon their habitat either in the shallow waters or in the depths. This conclusion is invalid and requires more explanatory approach which can be achieved by more research so as to derive a valid conclusion in which the two variables oxygen and relative habitats can be compared.

The Answer is B. More research is needed to reach a conclusion, including related variables.

Explanation:

The Scientists doesn't have enough data to prove this. This is merely a theory since it is not proven by an animal itself. Only with a valid experiment could he prove this to be true.

Hope This Helps!
