Will and Juan decided to make a snack after school: peanut butter and jelly sandwiches and a glass of cold milk. They assembled the following ingredients:breadwhole milkgrape jellypeanut butter. Which food likely has the FEWEST calories per gram of serving and why?

• Grape jelly because it's mostly simple sugars.

• Whole milk because most of the animal fat remains.

• Peanut butter because it contains plant-based fats.

• Bread because it contains a combination of complex carbohydrates, simply sugars and plant-based fats.

Living matter is at least sixty percent water. It makes sense, then, that cell membranes are made of phospholipids because

• phosphates dissolve in water.

• the lipids form an insoluble barrier.

• the bilayer acts to repel water.

• the lipids mix easily in a water environment.
