Q: Answer the following question given this paragraph: Sulfuric acid is produced in extremely large quantities in the United States (about 40 million tons/year). This material is manufactured by oxidizing sulfur to form sulfur trioxide. The SO 3 is then dissolved in water to form the sulfuric acid. Most of the sulfuric acid produced is used in fertilizers. This acid is also found in lead-acid car batteries. Q: What is sulfur trioxide dissolved in to form sulfuric acid? A:
Answer: water

Problem:OPTIONS:
- epidermis
- cuticle
- endoderm
- mesoderm

Answer the following question given this paragraph: Flatworms have a mesoderm cell layer and simple organ systems. They also show cephalization and bilateral symmetry. Q: What type of cell layer do flatworms have? A:
****
A: mesoderm

Answer the following question given this paragraph: Pressure shows how concentrated the force is on a given area. The smaller the area to which force is applied, the greater the pressure is. Think about pressing a pushpin, like the one in Figure below , into a bulletin board. You apply force with your thumb to the broad head of the pushpin. However, the force that the pushpin applies to the bulletin board acts only over the tiny point of the pin. This is a much smaller area, so the pressure the point applies to the bulletin board is much greater than the pressure you apply with you thumb. As a result, the pin penetrates the bulletin board with ease. Q: What is the effect on pressure when the area of applied force is very concentrated? A:
OPTIONS:
- direction increases
- pressure disperses
- pressure reduces
- pressure increases
pressure increases

Answer the following question given this paragraph: Q: What is the second state of photosynthesis? A:
OPTIONS:
- Phillip cycle
- glover cycle
- morton cycle
- calvin cycle

Answer: calvin cycle

Question: Answer the following question given this paragraph: Group 16 of the periodic table is also called the oxygen group. The first three elementsoxygen (O), sulfur (S), and selenium (Se)are nonmetals. They are followed by tellurium (Te) ( Figure below ), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive. Oxygen is a gas at room temperature, and the other elements in the group are solids. Q: What is group 16 of the periodic table referred to? A:
OPTIONS:
- sulfur group
- dioxide group
- acid group
- oxygen group
Answer: oxygen group

input: OPTIONS:
- presbyopia
- hyperopia
- myopia
- astigmatism Now, answer this question: Answer the following question given this paragraph: Another common vision defect is astigmatism, an unevenness or asymmetry in the focus of the eye. For example, rays passing through a vertical region of the eye may focus closer than rays passing through a horizontal region, resulting in the image appearing elongated. This is mostly due to irregularities in the shape of the cornea but can also be due to lens irregularities or unevenness in the retina. Because of these irregularities, different parts of the lens system produce images at different locations. The eye-brain system can compensate for some of these irregularities, but they generally manifest themselves as less distinct vision or sharper images along certain axes. Figure 26.8 shows a chart used to detect astigmatism. Astigmatism can be at least partially corrected with a spectacle having the opposite irregularity of the eye. If an eyeglass prescription has a cylindrical correction, it is there to correct astigmatism. The normal corrections for short- or farsightedness are spherical corrections, uniform along all axes. Q: Unevenness or asymmetry in the focus of the eye describes what visual defect? A:
A:
output:
astigmatism
