When skin is exposed to certain ultraviolet rays, the cells produce more melanin, causing the skin to darken. Over time, the cells can be damaged by these ultraviolet rays, which can lead to skin cancers. Which conclusion can most likely be drawn about the rates of skin cancer? A. Skin cells with a low concentration of melanin have the lowest risk of developing into cancer cells.

B. Skin cells with a high concentration of melanin have the highest risk of developing into cancer cells.

C. Skin cells with a low concentration of melanin have a lower risk of developing into cancer cells than cells with a high concentration of melanin.

D. Skin cells with a high concentration of melanin have a lower risk of developing into cancer cells than cells with a low concentration of melanin.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
