A biologist measured the rate of contractions of contractile vacuoles in a freshwater Paramecium with the organism surrounded by sucrose solutions with a range of different concentrations. Sucrose concentration (mol/L) Rate of Contractions (per minute)

0.00mol/L 16 per minute

0.05mol/L 13 per minute

0.10mol/L 8 per minute

0.15mol/L 5 per minute

0.20mol/L 1 per minute

0.25mol/L 0 per minute

0.30mol/L 0 per minute

0.35mol/L 0 per minute

When the Paramecium was returned to its natural habitat in pondwater the rate of contraction of the vacuole was 14.5 per minute. Estimate the solute concentration (osmolarity) of the pond water.

hes known as the father of   empiricism this concluding my reasonining im not 100% sure tho so only do it if u trust me ; c

a big wall across the mexican border so no drugs, terrorist, or illegal immigrants can come through : )    

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
