[10M]
Able to state how genetic engineering to improve the quality and quantity.
Sample answer
(a) Genetic engineering
P1: Transfer the beneficial genes from one organism to another organism.
P2: Obtain/produces genetic modified organism/transgenic
P3:crop yield/animal contain gene that able to enhance growth/nutritional properties/resistance against disease.
Culture tissue
P4: tissue/cell of parent plant are grown in culture medium.
P5: daughter plant is called clone.
P6;Produce many clone in a a short time/produce large fruit/maintain good characteristic of parent plant.
Sample answer
(b) Bad(B) Explanation(P)
B1 ; uses food additive
P4:give long term side effect/examples//reduce the nutrient/vitamin in the food.
B2: too much sugar
P5: increases the risk of diabetes
B3: foof colouring/yellow dye/tetrazine
P6: causes allergy reaction
B4:too much salt
P7:increase the risk of high blood pressure
B5: Sodium nitrate
P8:causes nausea/asthma(to certain people)
