Given a scientific passage and an answer, generate a question for the given answer.

[Q]: Passage: Figure 14.3 The Tongue The tongue is covered with small bumps, called papillae, which contain taste buds that are sensitive to chemicals in ingested food or drink. Different types of papillae are found in different regions of the tongue. The taste buds contain specialized gustatory receptor cells that respond to chemical stimuli dissolved in the saliva. These receptor cells activate sensory neurons that are part of the facial and glossopharyngeal nerves. LM 1600. (Micrograph provided by the Regents of University of Michigan Medical School ©️ 2012). Answer: papillae
[A]: What is the name of the small bumps that contain taste buds and covers the tongue?

[Q]: Passage: Dermal tissue covers the outside of a plant. It's like the plant's skin. Cells of dermal tissue secrete a waxy substance called cuticle. Cuticle helps prevent water loss and damage to the plant. Answer: cuticle
[A]: What do cells of dermal tissue secrete?

[Q]: Passage: Pepsinogen is an inactive form of pepsin; pepsin is the active form of the enzyme. Both enzymes catalyze the hydrolysis of peptide bonds. Chymotrypsin catalyzes the hydrolysis of peptide bonds following aromatic amino acids, while trypsin catalyzes the hydrolysis of peptide bonds following lysine and arginine. Aminopeptidase catalyzes the hydrolysis of amino acids from the N-terminal end of a protein, while carboxypeptidase catalyzes the hydrolysis of amino acids from the Cterminal end of a protein. Answer: aminopeptidase
[A]:
What catalyzes the hydrolysis of amino acids from the n-terminal end of a protein?
