Answer the following question given this paragraph: Pelvis The pelvis consists of four bones: the right and left hip bones, the sacrum, and the coccyx (see Figure 8.12). The pelvis has several important functions. Its primary role is to support the weight of the upper body when sitting and to transfer this weight to the lower limbs when standing. It serves as an attachment point for trunk and lower limb muscles, and also protects the internal pelvic organs. When standing in the anatomical position, the pelvis is tilted anteriorly. In this position, the anterior superior iliac spines and the pubic tubercles lie in the same vertical plane, and the anterior (internal) surface of the sacrum faces forward and downward. The three areas of each hip bone, the ilium, pubis, and ischium, converge centrally to form a deep, cup-shaped cavity called the acetabulum. This is located on the lateral side of the hip bone and is part of the hip joint. The large opening in the anteroinferior hip bone between the ischium and pubis is the obturator foramen. This space is largely filled in by a layer of connective tissue and serves for the attachment of muscles on both its internal and external surfaces. Several ligaments unite the bones of the pelvis (Figure 8.14). The largely immobile sacroiliac joint is supported by a pair of strong ligaments that are attached between the sacrum and ilium portions of the hip bone. These are the anterior sacroiliac ligament on the anterior side of the joint and the posterior sacroiliac ligament on the posterior side. Also spanning the sacrum and hip bone are two additional ligaments. The sacrospinous ligament runs from the sacrum to the ischial spine, and the sacrotuberous ligament runs from the sacrum to the ischial tuberosity. These ligaments help to support and immobilize the sacrum as it carries the weight of the body. Q: Designed to support the weight of the upper body when sitting and transfer this weight to the lower limbs when standing, what body structure consists of four bones: right and left hip bones, sacrum, and coccyx? Choices: - tissues - Chest - lungs - pelvis A:
pelvis
Answer the following question given this paragraph: Venules A venule is an extremely small vein, generally 8100 micrometers in diameter. Postcapillary venules join multiple capillaries exiting from a capillary bed. Multiple venules join to form veins. The walls of venules consist of endothelium, a thin middle layer with a few muscle cells and elastic fibers, plus an outer layer of connective tissue fibers that constitute a very thin tunica externa (Figure 20.7). Venules as well as capillaries are the primary sites of emigration or diapedesis, in which the white blood cells adhere to the endothelial lining of the vessels and then squeeze through adjacent cells to enter the tissue fluid. Q: A venule is an extremely small vein, generally 8100 micrometers in diameter. postcapillary venules join multiple capillaries exiting from a capillary bed. multiple venules join to form what? Choices: - clots - arteries - glands - veins A:
veins
Q: Answer the following question given this paragraph: In an anticline, rocks arch upward. A three-dimensional anticline is a dome. Q: What is a three-dimensional anticline called? Choices: - cave - volcano - cyclone - dome A:
A: dome
Question: Answer the following question given this paragraph: The gas giants are mostly made of hydrogen and helium. These are the same elements that make up most of the Sun. Astronomers think that most of the nebula was hydrogen and helium. The inner planets lost these very light gases. Their gravity was too low to keep them and they floated away into space. The Sun and the outer planets had enough gravity to keep the hydrogen and helium. Q: What are the gas giants mostly made of . Choices: - calcium and helium - nitrogen and helium - hydrogen and carbon - hydrogen and helium A:
Answer: hydrogen and helium
*Question*
Answer the following question given this paragraph: culture (outside the body under optimal growing conditions), the length of the cycle is about 24 hours. In rapidly dividing human cells with a 24-hour cell cycle, the G1 phase lasts approximately nine hours, the S phase lasts 10 hours, the G2 phase lasts about four and one-half hours, and the M phase lasts approximately one-half hour. In early embryos of fruit flies, the cell cycle is completed in about eight minutes. The timing of events in the cell cycle is controlled by mechanisms that are both internal and external to the cell. Q: The timing of events in what cycle - which lasts just minutes in fruit fly embryos - is controlled by mechanisms that are both internal and external to the cell? Choices: - circadian cycle - carbon cycle - life cycle - cell cycle A:
**Answer**
cell cycle
