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? A:

OPTIONS:
- vesicles
- mitosis
- Testes
- symphysis

Answer: symphysis

Problem: OPTIONS:
- toddler
- teenager
- i-40 age
- old age
Q: Answer the following question given this paragraph: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. Q: When does diseases like alzheimer's become more common? A:
Answer: old age

Problem:OPTIONS:
- longitudinal data
- manipulative data
- distinctive data
- morphological data

Answer the following question given this paragraph: Q: Researchers have long based their hypotheses about animal phylogeny on what? A:
****
A: morphological data

Answer the following question given this paragraph: A solution is a homogeneous mixture in which a solute dissolves in a solvent. Water is a very common solvent, especially in organisms. Q: What is the general name for the homogeneous mixture that is formed when a solute dissolves in a solvent? A:
OPTIONS:
- Reaction
- Combination
- Dissolvant

Answer the following question given this paragraph: There are three flat skeletal muscles in the antero-lateral wall of the abdomen. The external oblique, closest to the surface, extend inferiorly and medially, in the direction of sliding one's four fingers into pants pockets. Perpendicular to it is the intermediate internal oblique, extending superiorly and medially, the direction the thumbs usually go when the other fingers are in the pants pocket. The deep muscle, the transversus abdominis, is arranged transversely around the abdomen, similar to the front of a belt on a pair of pants. This arrangement of three bands of muscles in different orientations allows various movements and rotations of the trunk. The three layers of muscle also help to protect the internal abdominal organs in an area where there is no bone. The linea alba is a white, fibrous band that is made of the bilateral rectus sheaths that join at the anterior midline of the body. These enclose the rectus abdominis muscles (a pair of long, linear muscles, commonly called the "sit-up" muscles) that originate at the pubic crest and symphysis, and extend the length of the body's trunk. Each muscle is segmented by three transverse bands of collagen fibers called the tendinous intersections. This results in the look of "six-pack abs," as each segment hypertrophies on individuals at the gym who do many sit-ups. The posterior abdominal wall is formed by the lumbar vertebrae, parts of the ilia of the hip bones, psoas major and iliacus muscles, and quadratus lumborum muscle. This part of the core plays a key role in stabilizing the rest of the body and maintaining posture. Q: There are three flat skeletal muscles in the antero-lateral wall of what? A:
OPTIONS:
- shoulder socket
- thoracic cavity
- hip joint
- abdomen

Answer:
abdomen
