In an unstable environment where growing conditions are constantly changing, which mode of reproduction in plants provides the best chance for survival, and why? Sexual reproduction; it increases the chance of survival by producing many genetically identical offspring.

Sexual reproduction; it increases the chance of survival by producing many genetically identical offspring.

Asexual reproduction; it increases the chance of survival by introducing little genetic variation in offspring.

Sexual reproduction; it increases the chance of survival by introducing genetic variation in offspring.

Asexual reproduction; it increases the chance of survival by producing many genetically different offspring.

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.

Approximately what portion of the foods that we eat have been genetically modified in some way? a. fewer than 10% b. about 50% c. nearly 100%
