Explanation:
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x, y) parallel to the (x, y)-plane. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.
Viruses are much smaller then cells, viruses have genetic material DNA or RNA and cells also have genetic material
Answer and explanation;
-Stem cells, Adult stem cells and skin cells , have a similarities and they may also differ in a number of ways.
-A stem cell has not gone through the process of differentiation, so they have the potential to become any type of cell.
-Adult skin cells have gone through differentiation and cannot become another type of cell. Same case applies to the skin cells, they have already undergone differentiation;
-Similarity; The cells that are taken from the same person would have the same DNA.
-Difference; The skin cells and the adult stem cells have already gone through differentiation, whereas embryonic stem cells have not. The different genes that the types of cells have are turned on and off causing the differences.
