Explanation:

• Question 45: Pizza has distinct, separate components (crust, cheese, toppings) that are not uniformly distributed, so it is a heterogeneous mixture.
• Question 46: Oil and water do not mix uniformly; they form separate visible layers, making this a heterogeneous mixture.
• Question 47: Zinc is a pure substance made up of only one type of atom, so it is classified as an element.
