How do you think the reef will change when black band disease is present

A disease is threatening the Great Barrier Reef and recent information suggests that the Black Band Disease will migrate rapidly enough to kill whole coral colonies at a pace and place the population size of many coral species at risk of dramatic loss.

the answer is:

carbon dioxide

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.
