A student wanted to investigate the movement of water into and out of the plant cells. the student had the equipment shown in figure 11. the test tubes in the rack contain different concentrations of sodium chloride

the solutions were 0.1m, 0.2m, 0.3m, 0.4m and 0.5m sodium chloride solution

the test tubes in the beaker contain distilled water and there are three potato chips in each of the six test tubes

i) state why the test tube in the beaker only contains distilled water and three potato chips

ii) state two variables that need to be controlled in this investigation

iii) explain why the chips in the 0.5 sodium chloride lost mass

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
