Answer the following question given this paragraph: Development of the Vertebral Column and Thoracic cage Development of the vertebrae begins with the accumulation of mesenchyme cells from each sclerotome around the notochord. These cells differentiate into a hyaline cartilage model for each vertebra, which then grow and eventually ossify into bone through the process of endochondral ossification. As the developing vertebrae grow, the notochord largely disappears. However, small areas of notochord tissue persist between the adjacent vertebrae and this contributes to the formation of each intervertebral disc. The ribs and sternum also develop from mesenchyme. The ribs initially develop as part of the cartilage model for each vertebra, but in the thorax region, the rib portion separates from the vertebra by the eighth week. The cartilage model of the rib then ossifies, except for the anterior portion, which remains as the costal cartilage. The sternum initially forms as paired hyaline cartilage models on either side of the anterior midline, beginning during the fifth week of development. The cartilage models of the ribs become attached to the lateral sides of the developing sternum. Eventually, the two halves of the cartilaginous sternum fuse together along the midline and then ossify into bone. The manubrium and body of the sternum are converted into bone first, with the xiphoid process remaining as cartilage until late in life. Q: The accumulation of what cells begin the development of the vertebral column and thoracic cage? A:

OPTIONS:
- semiosis cells
- hindbrain cells
- False cells
- mesenchyme cells

Answer: mesenchyme cells

Answer the following question given this paragraph: Primary Lymphoid Organs and Lymphocyte Development Understanding the differentiation and development of B and T cells is critical to the understanding of the adaptive immune response. It is through this process that the body (ideally) learns to destroy only pathogens and leaves the body's own cells relatively intact. The primary lymphoid organs are the bone marrow and thymus gland. The lymphoid organs are where lymphocytes mature, proliferate, and are selected, which enables them to attack pathogens without harming the cells of the body. Q: The primary lymphoid organs are the bone marrow and what else? A:
OPTIONS:
- pinneal gland
- thyroid
- kidneys
- thymus gland
thymus gland

Answer the following question given this paragraph: Cumulus clouds are white and puffy. Convection currents make them grow upward and they may grow very tall. When they produce rain, they are called cumulonimbus. Q: What causes cumulus clouds to grow upward? A:
OPTIONS:
- moisture currents
- gas currents
- mantle currents
- convection currents

Answer: convection currents

input with options: Answer the following question given this paragraph: When waves of two different frequencies interfere, a phenomenon known as beating occurs. The frequency of a beat is the difference of the two frequencies. Q: When waves of two different frequencies interfere, what phenomenon occurs? A:
OPTIONS:
- making
- opening
- soaking
- beating
output:
beating
