You are attempting to determine the BMR of mice. You have several chambers of mice, each with their own temperature control. Firstly, what quantity could you be measuring in order to measure BMR? Second, when you check on the chambers, you see that the temperature control on one chamber malfunctioned and its temperature is much lower than you were trying to maintain but the other chambers worked as intended. Will the data from the defective chamber be usable for your experiment? Can you learn anything from it? Explain.

Scientific Notation

We have to deal with quantities that are extremely large or very small. For example- I may have 6,500,000,000 red blood cells, or the diameter of an iron atom is 0.000000011 inches. Numbers with many zeros can be inexpedient to work with, so scientists use scientific notation. It represents very large numbers or very small numbers in a simple form. We know that whole numbers can be extended to infinity, but we cannot write such large numbers on paper. Numbers that present in millions of places after the decimal point need to be represented simply. Thus, it is difficult to represent a few numbers in their extended form. Therefore, we use scientific notation.
