birds

Explanation:

the T.rex has a lot of similar features as some species of birds, for example, the bipedal.

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.  

i think its y= -4x-14
