To calculate the mean all you have to do is add all the numbers from the data set and then divide the answer between the number of data set. For example, if you data set is 2,3,4,5,6,then you add 2+3+4+5+6=20 Now you divide 20 between the total number of data, so from 2 to 6 you have 5 numbers. You divide 20/5 and that that is equal to 4.
Since you did not post your data set I can not tell you exactly the answer but you can use this information to walk you through it.
It’s been a while since I did this but B sounds the most accurate.
Nitrates are used by plants to make amino acids and proteins. Most of the phosphorus cycle takes place at ground level. Phosphate is released by the slow breakdown of rocks. What two main biological processes are responsible for the cycling of oxygen?
Solution:
According to the accepted current theory, known as the fluid mosaic model, the plasma membrane is composed of a double layer (bilayer) of lipids, oily substances found in all cells. The fluid mosaic model was first proposed by S.J. The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.
Thus this is the required answer.
Sedimentary, because of the glaciers that once covered Indiana they lithified which is a part of the rock cycle in the sedimentary division.
