dy = sin(2x)cos(2x) dxlet u = sin(2x)du/dx = 2cos(2x)dx = du/2cos(2x)dy = (cos(2x)/2cos(2x))dudy = du/2y = u/2y = sin(2x)/2

DNA and RNA are both essential components of cells, and thus life. The structure of DNA is similar to that of RNA in that these are both made of nucleotides, which in turn are made of the same basic units...

A number of differences exist between the structure of animal cells and plant cells. The most prominent difference is the presence of both cell walls and cell membranes in plants, while animal cells only ...
