1) A) Standard form= 1
Scientific form = 1 x 10^0

b) Standard form = 1000 scientific form = 1 x 10^3 c) Standard form = 0.00001 scienticif form = 1 x 10^-5

d) standard form =500000 scientific form = 5 x 10^5

e) standard form = 0.000021 scientific form = 2.1 x 10^-5

f) standard form = 10 x 10^6 scientific form = 10,000000

2) 1L and 1.000.000microliters 3) 280microliters and 0.28mL 4) 3860mL and 3.86L 5) Low power lens 10x 10x 100x
High power lens 10x 40x 400x
Oil immersion lens 10x 100x 1000x 6) 5 x 10^-3mm and 5.0microns 7) 1.96 x 10^-3 or 1.96microns 8) 4.9x10^-4mm o 0.49 micron 9) 9.8 x 10^-4mm or 0.98micron 10) 9.8 x 10^-5mm or 0.098micron 11) 9.8 x 10^-5mm or 0.098micron 12) 0.24micron or 2.4 x 10^-4mm 13) 0.005microns or 5x10^-6mm 14) The amoeba is eukaryotic while the bacteria cell is prokaryotic. You can tell this by simply observing that the bacteria cell has no nucleus while the amoeba has a nucleus. 15) Length = 4.9x10-2mm or 0.049microns
Width= 1.8x 10^ -3mm or 0.018microns 16) The elodea cells look shrunken in the salt solution. The cell membrane pulls away from the cell wall and are smaller in size. 17) The elodea cells loose water in the when placed in the salt solution. Water diffuses out of the cell to the environment which has a higher solute concentration. The appearance changes because the cells undergo plamolysis and now look weak and flaccid. The salt is more concentrated than the solutes in the cell. 18) They live in fresh water. This is because the cells look better in fresh water, and in salt solution, they undergo plasmolysis. 19) This is because the
