Problem: OPTIONS:
- the debris bowl
- the flow bowl
- the land bowl
- the dust bowl
Q: Answer the following question given this paragraph: The Dust Bowl taught people that soil could be lost by plowing and growing crops. This led to the development of new ways of farming that help protect the soil. Some of the methods are described in Figure below . Q: What historical event taught people that soil could be lost by plowing and growing crops and encouraged new methods to prevent erosion? A:
Answer: the dust bowl

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

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:
****
A: mesenchyme cells

Answer: epidermis

Question: Answer the following question given this paragraph: An emulsion is a colloidal dispersion of a liquid in either a liquid or a solid. Q: What term describes a colloidal dispersion of a liquid in either a liquid or a solid? A:
OPTIONS:
- mix
- suspension
- compound
- emulsion
Answer: emulsion

input: OPTIONS:
- sediment - nonpolar interactions
- refracted - nonpolar interactions
- polar-nonpolar interactions
- nonpolar-nonpolar interactions Now, answer this question: Answer the following question given this paragraph: Nonpolar-nonpolar interactions occur when two nonpolar liquids are mixed. An example of this is the interaction between toluene and octane (see Figures above and below ). The interactions between a molecule of toluene and a molecule of octane are relatively weak, but so are the toluene-toluene and octane-octane interactions. Because no strong intermolecular forces (like those between water molecules) need to be broken for mixing to occur, no strong interactions need to be formed in order for mixing to be a favorable process. Toluene and octane will form a homogeneous mixture. The phrase "like dissolves like" applies to these mixtures as well. In this case, nonpolar dissolves nonpolar. Q: What occurs when two nonpolar liquids are mixed? A:
A:
output:
nonpolar-nonpolar interactions
