The concept of a transgene has been broadly understood for more than 100 years, as the advent of genetic research made its way into the 20th century. As time went by, technologies evolved, and transgenes became widely used during the late 1970s and early '80s. Which is one reason scientists produce transgenic organisms? A) to create new species of organisms
B) to control microorganisms in the soil
C) to treat certain types of diseases

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.  

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
