I have two questions that I need some help with please.
1) Developing a scientific understanding of a natural phenomenon typically begins by A)making a prediction B)Testing a hypothesis C)proving an answer or D) making an obvservation. I'm pretty sure it's D because that's the first step in the scientific method.
2) A medical diagnosis is: A) an observation, B) an experiment C) A Theory or D) A hypothesis. I'm leaning towards theory because it's based on a hypothesis and has evidence to support it.
Thank you.
My experience it begins usually with an observation.
2) diagnosis: I think you have an infection. Sounds like a hypothesis to me. Doctors test it by giving you medicines.
1) Developing a scientific understanding of a natural phenomenon typically begins by making an observation (D). This is indeed the first step in the scientific method, where scientists carefully observe a phenomenon or collect data.
2) A medical diagnosis is not a theory, as a theory is a broad explanation that is supported by extensive evidence and has been tested in various ways. A medical diagnosis is also not an experiment because it doesn't involve manipulating variables or conducting controlled trials. A medical diagnosis is typically based on observation and analysis of symptoms, medical tests, and patient history. Thus, the most appropriate answer is observation (A), as it involves observing the signs and symptoms and drawing conclusions based on the available information.
You're on the right track with your answers! Let's go through each question and explain the reasoning behind the correct choices:
1) Developing a scientific understanding of a natural phenomenon typically begins by A) making a prediction, B) testing a hypothesis, C) proving an answer, or D) making an observation.
The correct answer is actually B) testing a hypothesis. While making an observation is an important step in the scientific process, it is usually not the starting point. Developing a scientific understanding usually begins with forming a hypothesis, which is an educated guess or a proposed explanation for the phenomenon. Once a hypothesis is formulated, scientists design experiments or gather data to test whether the hypothesis is supported or refuted. Therefore, the correct answer is B) testing a hypothesis.
2) A medical diagnosis is: A) an observation, B) an experiment, C) a theory, or D) a hypothesis.
Your inclination towards C) a theory for a medical diagnosis is understandable, but it is not the correct answer in this case. A theory in science is a well-substantiated explanation of certain phenomena based on a large body of evidence. In medicine, a diagnosis is a specific identification or recognition of a disease or condition in a patient based on signs, symptoms, and tests. It involves the application of medical knowledge and expertise to interpret data and make an assessment. Therefore, the correct answer is A) an observation, as a doctor observes the patient's symptoms and uses that information to form a diagnosis.
In summary:
1) The correct answer is B) testing a hypothesis.
2) The correct answer is A) an observation.
Remember, it's always helpful to use critical thinking and consider the context of the question to arrive at the correct answer.
