If the thickness of the liquid layer below the coverslip is 0.1 mm, what is the volume density of the white blood cells (express on a per mm3 basis to four significant figures)? ]]> 2022-02-03 14:04:48 UTC https://padlet.com/usictech/nol5i6h83mfmbblg/wish/2027534066 usictech https://padlet.com/usictech/nol5i6h83mfmbblg/wish/2027534068 1) A light microscope at x400 magnification has a field diameter estimated at 0.425 mm. Observing a sample of leaf surface at this magnification, you count 25 hairs in a dingle field of view. What is your estimate of the area density (frequency) of hairs, expressed on a per mm² basis, to three significant figures? ]]> 2022-02-03 14:04:48 UTC https://padlet.com/usictech/nol5i6h83mfmbblg/wish/2027534068
