(b) Find the resultant of a force 4N and 8N acting at the same point on an object if the forces act in the same direction in the same straight line

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.  

answer: a) a compound microscope has a greater magnification ability than a simple microscope.

explanation:

it's c. (to reduce the greenhouse effect/carbon gasses)
