Which best describes the law of conservation of mass? The coefficients in front of the chemicals in the reactants should be based on the phys cal state of the products.
Products in the form of gases are not considered a part of the total mass change from reactants to products.
When reactants contain both a solid and a liquid, the solid counts toward the overall mas and the liquid does not.
The mass of the reactants and products is equal and is not dependent on the physical state of the substances.

What is the relation ship between structure and function in an organism

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.
