Answer:
The answer is C.
Explanation:
Halogens occupy Group 17 of the Periodic Table. This group contains six different nonmetallic elements.
The correct answer is C. Students communicate results in laboratory reports, and professional scientists communicate results in scientific journals.
Explanation:
Both students and scientists can carry out scientific research that involves studying a phenomenon by using the scientific method and scientific instruments. However, professional scientists and students differ in their level of knowledge and expertise in science. This makes scientific research made by scientists to have some differences in comparison to scientific research by students.
One of these differences is the way results are communicated. Indeed, students develop simple scientific research and the results are communicated in laboratory reports at school, colleges, etc. On the other hand, professional scientists develop complex research. Due to this, results are communicated in academic texts with strict criteria and that can be seen by other scientists, these are known as scientific journals.
Answer:
This is called replication.Generally, in an experimental set up experimental findings needed to be repeated continuously until a reasonable similar conclusion is reached.
Scientists needed to carry out similar experimental findings to get a similar results, to arrive at a reasonable conclusion.
It is the stage that is important for them to check the results arrived at.Replication therefore helps to identify any variability in the experimental results,for accurate results.
Explanation:
Do you mean by-product? Because in that case no. Oxygen is not a by-product of the Krebs Cycle, but Carbon Dioxide is.
False, the angle is consistently the same, yet the placement of the Earth at this angle directed at the sun is what allows the Earth to have seasons (Spring, Summer, ...) So the answer is false.
