In which situation would it be least likely for a scientist to revise her experimental methods?
it het results support her hypothesis
if her data do not support her hypothesis
no conclusions can be drawn from the data
results are the same after repeating the procedure

results are the same after repeating the procedure

Explanation:

The realization of a scientific experiment involves the manipulation of different variables that, according to scientists, are the cause of the phenomenon to be confirmed. Thanks to experiences, theories tend to find factual support and causal explanations. However, for an experiment to be validated, a whole process of observation and review of several factors is necessary.

Scientists should review their experimental methods for several moments, to make sure that their experiment will give a true and concrete result. This review should be done when: the results confirm your hypothesis, if your data does not support your hypothesis and if no conclusions can be drawn from the data. However, when the results are the same after repeating the procedure, a review is not necessary; generally, several revisions have already been made until the experiment reaches this point.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
