- astigmatism
Q: 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:
Answer: astigmatism

Answer the following question given this paragraph: Figure 13.6 Bacteria are divided into two major groups: Gram-positive and Gram-negative. Both groups have a cell wall composed of peptidoglycans: In Gram-positive bacteria, the wall is thick, whereas in Gram-negative bacteria, the wall is thin. In Gram-negative bacteria, the cell wall is surrounded by an outer membrane. Q: Gram-positive and gram-negative bacteria are distinguished by thickness of what? A:
OPTIONS:
- cell membrane
- cell weight
- cell length
- cell wall
cell wall

Answer the following question given this paragraph: The first case of West Nile virus in North America occurred in 1999. Within just a few years, the virus had spread throughout most of the United States. Birds as well as humans can be infected with the virus. Birds often fly long distances. This is one reason why West Nile virus spread so quickly. Q: Where did west nile first appear? A:
OPTIONS:
- Central America
- North Africa
- Southeast Asia
- north america

Answer: north america
