Ascientist conducting an experiment quickly saw that she was not getting the results she expected. instead of continuing to collect data, she went back to redesign the experiment until the data came out the way that the hypothesis predicted. the scientist’s work did not follow the scientific method. which statement best explains why?
she followed the steps of the scientific method, but in the wrong order.
she made improvements to her experimental design rather than keeping it the same.
she failed to look at the data objectively by trying to get a desired result.
she carried out multiple trials rather than carrying out one trial correctly.

The correct answer is third statement.

Explanation:

The objective of the scientific method is to answer the question that the scientist has generated. In the mentioned case, the scientist has violated the scientific method as she is attempting to manipulate the data in order to support her hypothesis. The scientist should observe the data objectively and accept the fact that her data is not supporting her hypothesis. Even if the hypothesis has been proved to be false, the scientist still can answer their question, thus, the experiment would not be considered false.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
