The respiratory system allows for gas exchange to happen in the lungs. how does the respiratory system affect the cardiovascular system? the respiratory system supplies the carbon dioxide that the cardiovascular system transports to the different cells for the production of energy. the respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy. the cardiovascular system supplies the carbon dioxide that the respiratory system transports to the different cells for the production of energy. the cardiovascular system supplies the oxygen that the respiratory system transports to the different cells for the production of energy.

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.

The wings of insects, birds, and bats evolved independently but carry out similar functions. this is an example of a. analogous structures. b. embryonic structures. c. vestigial structures. d. homologous structures.
