Q2. A parent feeds their child two ice creams. Which nutrient’s digestion would be most directly impacted?

Background

Topic: Digestion and Nutrient Breakdown

This question tests your understanding of which nutrients are present in ice cream and how they are digested.

Key Terms:

• Carbohydrates: Sugars and starches found in foods.

• Proteins: Building blocks for body tissues.

• Fats: Lipids, important for energy storage.

Step-by-Step Guidance

1. Consider the main ingredients in ice cream (milk, sugar, cream).

2. Identify which macronutrients are most abundant in ice cream.

3. Recall which digestive enzymes are involved in breaking down these nutrients.

Q3. Which is the CORRECT order of the key stages of food processing?

Background

Topic: Digestive System Processes

This question tests your knowledge of the sequence of events in food processing in animals.

Key Terms:

• Ingestion: Taking in food.

• Digestion: Breaking down food into smaller molecules.

• Absorption: Uptake of nutrients into the body.

• Elimination: Removal of undigested material.

Step-by-Step Guidance

1. List the four main stages of food processing.

2. Arrange them in the logical order from start to finish.

3. Think about what happens first when you eat, and what happens last.

Q4. Spaghetti contains complex carbohydrates and will activate amylase first, highly branched roots. Which advantage does this structure provide?

Background

Topic: Plant Root Structure and Function

This question tests your understanding of how root structure affects nutrient and water uptake.

Key Terms:

• Amylase: Enzyme that breaks down starch.

• Highly branched roots: Roots with many branches, increasing surface area.

Step-by-Step Guidance

1. Recall the function of amylase in digestion.

2. Think about why plants have highly branched roots.

3. Consider how increased surface area benefits the plant.

Q5. Which of the following statements is TRUE about nutrient absorption?

Background

Topic: Nutrient Absorption in the Digestive System

This question tests your knowledge of how nutrients are absorbed in the digestive tract.

Key Terms:

• Absorption: Movement of nutrients from the digestive tract into the bloodstream.

• Villi: Finger-like projections in the small intestine that increase surface area.

Step-by-Step Guidance

1. Review the structure of the small intestine and its role in absorption.

2. Recall how villi and microvilli contribute to nutrient uptake.

3. Think about the differences between absorption in the stomach and small intestine.
