Question

examples of pairs where they both are quick breads includes:
biscuits and cinnamon rolls
pancakes and pita bread
muffins and waffles
crepes and english muffins
question 5
double acting baking powder:
needs heat and liquid to react
needs only heat to react
needs only liquid to react
none of the above

Explanation:

Quick breads are leavened by chemical agents (like baking powder or baking soda) rather than yeast. Muffins and waffles are both quick breads. Biscuits are quick breads but cinnamon rolls are usually yeast - leavened. Pancakes are quick breads but pita bread is often yeast - leavened. Crepes are a type of thin pancake (quick bread) but English muffins are usually yeast - leavened.

Double - acting baking powder reacts in two stages. The first reaction occurs when it comes into contact with liquid (moisture) and the second reaction occurs when it is heated. So it needs both heat and liquid to fully react.

Answer:

For the first question (pairs of quick breads): Muffins and waffles.
For the second question (double - acting baking powder): Needs heat and liquid to react.
