Question 9Students investigated osmosis in carrot tissue. They cut cores of carrot tissuethat were identical in size. They weighed the carrot cores then placed threecores in each beaker of solution. Each beaker contained a differentconcentration of sugar solution. After 24 hours, they blotted the carrot coresdry and re-weighed them.The diagram shows their apparatus.0.0 mol/dm³ 0.2 mol/dm³ 0.4 mol/dm³ 0.6 mol/dm³ 0.8 mol/dm³The students' results are presented the table below.Final Mass/gMassChange/gSugarsolutionconcentration/mol dm-30.00.20.40.60.81.0(a)(b)(c)(d)InitialMass/g3.63.03.03.42.73.34.23.22.72.92.12.4+ 0.6+0.2-0.3-0.5-0.6- 0.91.0 mol/dm³% change inmass+16.7+6.7-6.7-14.7Calculate the missing values in the final column of the table.Plot the data in a suitable form, showing the relationship between thepercentage change in mass and the concentration of the sugarsolutionExplain the relationship between the concentration of the sugarsolution and the percentage change in mass of the carrot cores.Explain why the students calculated the percentage change in massof the carrot cores, rather than the change in mass.

Question 21>In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.What hypothesis was being tested in the initial experiment with open versus sealed jars?A.The type of meat used affects the likelihood of spontaneous generation.B.Spontaneous generation can occur only if meat is exposed to air.C.Spontaneous generation is more likely during the long days of summer.D.Maggots do not arise spontaneously, but from eggs laid by adult flies.
Question 6 In the first part of the experiment, there were only a few colonies on the streptomycin positive plate. In the second part, there are a large number of colonies on the streptomycin positive plate that was inoculated with the antibiotic resistant strain. What is the most likely explanation for this difference? 1. The antibiotic resistant strain was composed of a large number of individuals with resistance to streptomycin 2. The exposure to streptomycin caused a mutation in a few individuals
