Forth maize seeds were sown on a raised bed and thirty-five seeds germinated.

(a) (i) Calculate the percentage of the maize seeds that germinated [2 marks]

(ii) What is the percentage of the maize seeds that did not germinate? [2 marks]

(b) State four conditions that could have enhanced the germination of the thirty-five seeds. [4 marks]

(d) Give two industrial uses of maize seeds.

(a)(i) Percentage of the maize seeds that germinated = \(\frac{\text{No of germinated seeds}}{\text{no of seeds sown}} \times \frac{100}{1}\)

Percentage of the maize seeds that germinated = \(\frac{35}{40} \times \frac{100}{1}\) = 87.5%

(ii) Percentage of the maize seeds that did not germinate = \(\frac{\text{No of ungerminated seeds}}{\text{no of seeds sown}} \times \frac{100}{1}\)

Percentage of the maize seeds that did not germinate = \(\frac{5}{40} \times \frac{100}{1}\) = 12.5%

Percentage of the maize seeds that did not germinate = 100% of seeds that germinate
100 - 87.5% = 12.5%

(b) Conditions that enhanced the germination of the thirty-five seeds:

(d) Industrial uses of maize seeds:
