Dr. Bunsen Honeydew is interested in studying the lipid makeup of the cell membranes from a mammal whose habitat is Death Valley (high temperatures of about 115 0F...yikes!). What is he most likely going to find (Choose any/all that apply): Group of answer choices The membranes contain really long chain fatty acids that contain multiple cis-double bonds The membranes contain minimal to no cholesterol. The membranes contain minimal to no phospholipids. The membranes contain fatty acid chains of moderate length with a high degree of unsaturation (they will have several double bonds). The membranes contain long fatty acid chains that are completely saturated (they contain no double bonds).

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.
