How do genetic factors, environmental factors, and pathogenic agents affect both individual and public health?

Genetic factors are very important because genes make our strong immune system that is not badly affected by weak traits or disease. Environmental factors are important because they can cause/spread disease.

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.  

did u get the answer? /? ? / me
