When two mechanical waves have a displacement in the same direction, and they overlap, what will the resulting wave look like and why?

the new wave will have the same displacement as the original waves due to constructive interference.

the new wave will have a smaller displacement than either of the original waves due to destructive interference.

the new wave will have a greater displacement than either of the original waves due to constructive interference.

the new wave will have the same displacement as the original waves due to destructive interference.

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.
