*NUMBER TWO*
(2a)
Tabular form
-Adult X-
TWO FOOD NUTRIENTS
(i) vitamins
(ii) minerals
ONE END PRODUCT OF DIGESTION
(i) glucose
-Adult Y-
TWO FOOD NUTRIENTS
(i) carbohydrates
(ii) protein
ONE END PRODUCT OF DIGESTION
(i) amino acids.
(2bi)
Constipation is a condition characterized by infrequent bowel movements and difficulty passing stool.
(2bii)
Adult X, who had a meal of vegetables, is less likely to suffer from constipation.
(2biii)
(PUCK ANY ONE)
(i) Vegetables are high in fiber, which adds bulk to the stool and helps in regular bowel movements.
(ii) Vegetables are also high in water content, which helps soften the stool and makes it easier to pass.
(iii) The presence of vitamins and minerals in vegetables helps promote a healthy digestive system and proper bowel function.
(2c)
(PICK ANY THREE)
(i) White bread provides a quick source of energy due to its high carbohydrate content.
(ii) The fried egg provides protein, which helps in muscle growth and repair.
(iii) The combination of white bread and fried egg can provide a balance of essential nutrients for the body.
(iv) The meal can be filling and satisfying, helping to reduce hunger and provide satiety.
(2di)
(PICK ANY TWO)
(i) Inadequate intake of essential nutrients: People may not consume a balanced diet that provides all the necessary vitamins, minerals, and macronutrients.
(ii) Poor absorption of nutrients: Certain medical conditions or digestive disorders can impair the absorption of nutrients from food.
(iii) Increased nutrient needs: Certain life stages, such as pregnancy or lactation, as well as certain medical conditions, may require higher nutrient intake than usual, and if these needs are not met, malnutrition can occur.
(2dii)
(PICK ANY THREE)
(i) Stunted growth: Malnutrition can lead to a lack of essential nutrients needed for proper growth and development, resulting in reduced height and weight for age.
(ii) Weak immune system: Malnutrition weakens the immune system, making children more susceptible to infections and diseases.
(iii) Delayed cognitive development: Inadequate nutrition can affect the brain's development, leading to learning difficulties and impaired cognitive function.
(iv) Lack of energy: Malnourished children may experience fatigue and lack of energy, affecting their overall physical and mental well-being.
