What type of carbon-based molecule are most enzymes?

Proteins, which are the building blocks from which the structures of living organisms are constructed (this includes almost all enzymes, which catalyse organic chemical reactions) Nucleic acids, which carry genetic information. Carbohydrates, which store energy in a form that can be used by living cells.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
