I. Leafy sea dragons have leaf-like appendages that mimic the fronds of the sea kelp beds in which they inhabit. This inherited characteristic enables the delicate sea dragon to evade capture by its enemies. The evolution of these leafy appendages is an example of which of the characteristics of life?

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

substitution is the answer in this case

condensation. good luck!
