The medium ground finch lives on the Galapagos Islands. Birds with beaks of all sizes were originally part of this population. The finches are seed eaters. The types of food available for them to eat depends on the weather. During wet years, there is a large variety of food. During dry years, there is less food, and large, tough seeds are more abundant than small seeds.

After a long drought, researchers noticed certain differences in the population of medium ground finches living compared to those who lived before the drought. What was different about the finches after the drought?
A.
They had smaller wings.
B.
They had larger wings.
C.
They were a new species.
D.
They had larger beaks.

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.

Anne, an intern in a microbiology lab, was observing the characteristics of various specimens of protists. match each specimen to the category of protist to which it belongs.
