Question options:
1. developing a hypothesis to explain collected data
2. proving a theory and writing a new scientific law
3. collecting data through observation and measurement
4. observing and experimenting to test a hypothesis
Answer:
2. proving a theory and writing a new scientific law
Explanation:
Providing a theory and write a new scientific law is not a step of scientific investigation. To prove a law a theory, its take many years of research.
There are steps of scientific investigations below,
1. Make an Observation.
2. Form a Question.
3. Form a Hypothesis.
4. Conduct an Experiment.
5. Analyze the Data and
6. Draw a Conclusion.
These step of scientific investigation does not include to write a theory and scientific law.
A. As the pan of the water is heated, the water molecules moves faster and father apart.
As the water is heated, the water molecules gains more kinetic energy as the result of the heat that is been added by the stove. The gained kinetic energy allows the molecules to move faster and to move father away from one another.
b. If there are more water inside the pan, the same phenomenon experienced in the [a] above will still occur, but this time around it will take a longer period for the reaction to occur. This is because, there are more water particles in the pan and therefore it will take longer time before the heat from the stove circulate round all the particles.
Answer: False
Explanation:
This is a false statement because researches have shown that Adrenaline is helping and it is good for long-term memory and if we have lots of Adrenaline that is making our brain work and remember better and more.
If we are recalling being insulted, falling, or something more, we can still retrieve those memories because of the Adrenaline and that means that it is not decreasing the ability to remember the trauma.
Those cells are called neurons
Your pulse goes down, because you’re not doing any physical activity, which raises your pulse.
