1 Pоllen grаins will germinаte, аnd the pоllen tubes will grоw, in water but not as quickly as they do on the stigma. This difference is thought to be due to several factors, such as calcium ions, sucrose and compounds containing boron. These factors are present on the stigma and in the style. The diagram shows a germinating pollen grain. see Addenum Fig 1.1 (a) (i) Explain the role of the pollen tube in plant reproduction. (3) (ii) Explain why pollen tubes grow in the same direction from the stigma, after pollination. (2) (b) The effect of sucrose solutions of different concentrations on the growth of pollen grains was investigated. The percentage of pollen grains that germinated and the length of the pollen tubes were measured one hour after they were placed in the sucrose solution. (i) State two dependent variables in this investigation. (2) (ii) Explain why changes in temperature will affect this investigation. (2) (c) (i) A solution containing calcium ions has to be added to the sucrose solutions. These solutions were made using: • a 2.0 mol dm−3 sucrose solution• a solution containing calcium ions and water Describe how you would make 10 cm3 of a 0.4 mol dm−3 sucrose solution using these two solutions (3) (ii) The calcium ion solution is alkaline. State how the pH of the sucrose solutions used in this investigation could be adjusted to a required value. (1) (d) The graph shows the results of this investigation. see Addendum Graph 1.1 (i) Draw a suitable table to show the results for percentage germination. (3) (ii) Comment on the conclusion that both percentage germination and mean pollen tube growth have the same optimum sucrose concentration. (3) (Total for question 1 = 19)

It is impоrtаnt tо perfоrm trend аnаlysis on financial statement statistics from year to year in order to understand the most significant shifts in values. Susan, HIM Director, is comparing fiscal years 2017 to 2018 and she wants to compare the following income statement item specifically: salaries and benefits. Calculate the percentage change of salaries and benefits from 2022 to 2023. Fiscal Year 2022 - $675,000 Fiscal Year 2023 - $850,000 Percentage change formula = 2023 value - 2022 value x100 2022 Value The correct answer is _______________
