• A single gene gives the characteristic
• The gene operates with no environmental effects
Discontinuous variation

Read pages 6 to 9 and write 10 multiple choice questions (each with 4 possible answers) on the subject of species, breeds, varieties, selective
breeding and cross-breeding

Which salt is produced when nitric acid is added to lithium hydroxide?A. Lithium nitride
Close, but incorrect

Which salt is produced when nitric acid is added to lithium hydroxide?A. Lithium nitrideB. Nitric oxide
Incorrect, but sounds “scientific”

Which salt is produced when nitric acid is added to lithium hydroxide?A. Lithium nitrideB. Nitric oxideC. Lithium nitrate
Correct!
