Sandra examined some animal cells using a compound microscope. Under normal conditions, the cells have an approximate salinity of 1 M NaCl and resemble the slide shown in picture 1. If the cells are submerged in a 0.8 M NaCl solution, what will happen to the cells?
A.
Water will move into the cells and they will swell as in picture 2.

B.
Water will move into the cells until they swell and burst as in picture 4.

C.
Nothing will happen; they will look the same as in picture 1.

Astudent analyzed ears of corn that demonstrated two traits in the f2 kernels, purple or white colors and smooth on wrinkled shapes. a tabulation of 135 individual kernels gave the following results: purple and smooth = 75 white and smooth = 28 purple and wrinkled = 24 white and wrinkled = 8 what would be the only phenotype present in the f1 ger

Diego conducted an experiment to find out what kind of ball bounces the highest when dropped from a five-foot platform. he used a golf ball, a tennis ball, and a soccer ball. he dropped each ball from the balcony once. diego recorded his observations after each drop. what can diego do to best improve the reliability of his results? a) drop each ball from the platform three more times b) record his observations in more than one unit c) write at least two scientific questions after the experiment is complete d) share his results with other people who have done similar experiments you for the !
