Answer the following question given this paragraph: Birds have air sacs that store inhaled air and push it into the lungs like bellows. This keeps the lungs constantly filled with oxygenated air. The lungs also contain millions of tiny passages that create a very large surface area for gas exchange with the blood (see Figure below ). Q: Birds have air sacs that store inhaled air and push it into their what? Choices: - beaks - bones - abdomens - lungs A:
lungs
Answer the following question given this paragraph: The study of rock layers is called stratigraphy. Laws of stratigraphy help scientists determine the relative ages of rocks. The main law is the law of superposition. This law states that deeper rock layers are older than layers closer to the surface. Q: What do we call the study of rock layers? Choices: - geology - mineralogy - sedimentary - stratigraphy A:
stratigraphy
Q: Answer the following question given this paragraph: Covalent bond energies can be used to estimate the enthalpy changes of chemical reactions. Q: Covalent bond energies can be used to estimate the enthalpy changes of what? Choices: - crystals reactions - Pressure reactions - liquid reactions - chemical reactions A:
A: chemical reactions
Question: Answer the following question given this paragraph: Flexion and Extension Flexion and extension are movements that take place within the sagittal plane and involve anterior or posterior movements of the body or limbs. For the vertebral column, flexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion, such as straightening from a flexed position or bending backward. Lateral flexion is the bending of the neck or body toward the right or left side. These movements of the vertebral column involve both the symphysis joint formed by each intervertebral disc, as well as the plane type of synovial joint formed between the inferior articular processes of one vertebra and the superior articular processes of the next lower vertebra. In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension. Q: What type of flexion is the bending of the neck or body toward the right or left side? Choices: - orbital - cylindrical - ventral - lateral A:
Answer: lateral

Q: Subducting plate and epicenter are terms related to what phenomenon? Choices: - hurricane - tidal wave - eruption - earthquake A:
**Answer**
earthquake
Answer the following question given this paragraph: Q: What in the axils of leaves and stems give rise to branches? Choices: - nodules - meristems - chloroplasts - axillary buds A:
axillary buds
