Answer the following question given this paragraph: Symphysis A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis ("growing together"). Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. This gives symphyses the ability to strongly unite the adjacent bones, but can still allow for limited movement to occur. Thus, a symphysis is functionally classified as an amphiarthrosis. The gap separating the bones at a symphysis may be narrow or wide. Examples in which the gap between the bones is narrow include the pubic symphysis and the manubriosternal joint. At the pubic symphysis, the pubic portions of the right and left hip bones of the pelvis are joined together by fibrocartilage across a narrow gap. Similarly, at the manubriosternal joint, fibrocartilage unites the manubrium and body portions of the sternum. The intervertebral symphysis is a wide symphysis located between the bodies of adjacent vertebrae of the vertebral column. Here a thick pad of fibrocartilage called an intervertebral disc strongly unites the adjacent vertebrae by filling the gap between them. The width of the intervertebral symphysis is important because it allows for small movements between the adjacent vertebrae. In addition, the thick intervertebral disc provides cushioning between the vertebrae, which is important when carrying heavy objects or during high-impact activities such as running or jumping. Q: A cartilaginous joint where the bones are joined by fibrocartilage is called a what? Choices: - vesicles - mitosis - Testes - symphysis A:
symphysis
Answer the following question given this paragraph: Cnidarians have an incomplete digestive system with a single opening. The opening is surrounded by tentacles, which are covered with nematocyst cells and used to capture prey. Digestion takes place in the digestive cavity. Nutrients are absorbed and gases are exchanged through the cells lining this cavity. Fluid in the cavity supports and stiffens the cnidarian body. Q: What organism is characterized by an incomplete digestive system and a single, tentacled opening? Choices: - annelids - prokaryotes - sponges - cnidarians A:
cnidarians
Q: Answer the following question given this paragraph: Evaporation occurs when water on the surface changes to water vapor. The sun heats the water and gives water molecules enough energy to escape into the atmosphere. Q: What occurs when water on the surface changes to water vapor? Choices: - oxidation - photosynthesis - condensation - evaporation A:
A: evaporation
Question: Answer the following question given this paragraph: Most of the time, you breathe without thinking about it. Breathing is mostly an involuntary action that is controlled by a part of your brain that also controls your heart beat. If you swim, do yoga, or sing, you know you can control your breathing, however. Taking air into the body through the nose and mouth is called inhalation . Pushing air out of the body through the nose or mouth is called exhalation . The woman pictured below is exhaling before she surfaces from the pool water ( Figure below ). Q: What is the term for expelling air out of the body through the nose or mouth? Choices: - induction - inhalation - perspiration - exhalation A:
Answer: exhalation

Answer the following question given this paragraph: Science is a process of knowing about the natural universe through observation and experiment. Q: Science is a process of knowing about the natural universe through what two actions? Choices: - thinking and guessing - changes and experimentation - guessing and observing - observation and experimentation A:
**Answer**
observation and experimentation
Q: Answer the following question given this paragraph: Discussion The minus sign indicates that acceleration is to the left. This sign is reasonable because the train initially has a positive velocity in this problem, and a negative acceleration would oppose the motion. Again, acceleration is in the same direction as the change in velocity, which is negative here. This acceleration can be called a deceleration because it has a direction opposite to the velocity. Q: Deceleration is the opposite of what? Choices: - stopping - stimulation - vibration - acceleration A:
A: acceleration
