Answer
One example of a limitation of the scientific method is that it is based on our basic knowledge or the basis of investigation or our ability to interpret results. This means that it may not always account for accidental discoveries or changes in the natural world that cannot be easily observed or measured.
Step 2
Where do scientists usually publish the results and conclusions of their investigations?

Answer
Scientists typically publish the results and conclusions of their investigations in scientific journals. These journals serve as a platform for disseminating research findings to the wider scientific community.

Answer
To expose the tricuspid valve, I cut through the right side of the heart using a scalpel. This allowed for direct access to the internal structures of the heart.

Answer
The first thing I established was the resting (pulse) rate or resting (breathing) rate of the subjects before any exercise was performed.

Answer
To measure pulse rate, I felt or located the pulse, counting heartbeats over a specified time period. For breathing rate, I counted breaths over the same stated time and then repeated this process to find an average.
