Answer the following question given this paragraph: Plants called epiphytes grow on other plants. They obtain moisture from the air and make food by photosynthesis. Most epiphytes are ferns or orchids that live in tropical or temperate rainforests (see Figure below ). Host trees provide support, allowing epiphyte plants to obtain air and sunlight high above the forest floor. Being elevated above the ground lets epiphytes get out of the shadows on the forest floor so they can get enough sunlight for photosynthesis. Being elevated may also reduce the risk of being eaten by herbivores and increase the chance of pollination by wind. Q: What type of plants grow on other plants? Choices: - bryophytes - parasites - legumes - epiphytes A:
epiphytes
Q: Answer the following question given this paragraph: As mentioned earlier, echinoderms show radial symmetry. Other key echinoderm features include an internal skeleton and spines, as well as a few organs and organ systems. Although echinoderms look like they have a hard exterior, they do not have an external skeleton. Instead, a thin outer skin covers an internal skeleton made of tiny plates and spines. This provides rigid support. Some groups of echinoderms, such as sea urchins ( Figure below ), have spines that protect the organism. Sea cucumbers use these spines to help them move. Q: What type of symmetry do echinoderms show? Choices: - mirrored - lateral - parallel - radial A:
A: radial
Question: Answer the following question given this paragraph: Q: A system in what state cannot spontaneously change, and therefore can do no work? Choices: - equality - balance - stability - equilibrium A:

Answer the following question given this paragraph: Chymotrypsin is found in the small intestine and catalyzes the hydrolysis of peptide bonds following aromatic amino acids. Lactase is found in the small intestine and catalyzes the hydrolysis of lactose. Pepsin is found in the stomach and catalyzes the hydrolysis of peptide bonds, primarily those that occur after aromatic amino acids. Maltase is found in the small intestine and catalyzes the hydrolysis of maltose. Q: What enzyme is found in the small intestine catalyzes the hydrolysis of lactose? Choices: - elastases - lipase - amylase - lactase A:
**Answer**
lactase
