When news of a scientific discovery is reported, readers must assess the credibility of the claim. for scientific discoveries in general, which statement indicates a valid and credible claim? a. the scientist aimed for precision and accuracy by using a small sample size. b. the scientist followed strict standards of investigation and scientific methodology throughout the research. c. the scientist assured that the experiment was broad in scope by testing many variables in each trial. d. no other scientists replicated the experiment to avoid the legal issues of patent infringement.

The correct answer is B. The scientist followed strict standards of investigation and scientific methodology throughout the research.

It is important to follow the standard of investigation in order to answer the question as well as possible.  Scientific method include a few steps that help scienties focus on your scientific question and work through observations and avaliable data.

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 !

its temperature is increasing. this causes molecular vibrations to increase.
