There are over 2000 kinds of edible insects in the world, and they are becoming an increasingly popular source of protein. One cup of cricket flour contains over 28 grams of protein. The building blocks of the protein in cricket flour are

• amino acids

• water

• simple sugars

• carbohydrates

Protein synthesis is accomplished primarily by the interaction of which two cell structures?

• vacuoles and mitochondria

• ribosomes and vacuoles

• nuclei and ribosomes

• nuclei and mitochondria

Certain seaweeds contain a greater concentration of iodine inside their cells than there is in the seawater surrounding them. The energy required to maintain this concentration difference is most closely associated with the action of

• mitochondria

• vacuoles

• nuclei

An ameba is a single-celled organism. It uses its cell membrane to obtain food from its environment, digests the food with the help of organelles called lysosomes, and uses other organelles to process the digested food. From this, we can best infer that

• all single-celled organisms have lysosomes to digest food

• amoebas are capable of digesting any type of food molecule

• single-celled organisms are as complex as multicellular organisms

• structures in amoebas have functions similar to organs in multicellular organisms
