PLZ HELP NOW!! A molecular biologist is developing a computer model of the transcription of a gene into RNA.
Which event should be included in the model before transcription occurs?
A- the removal of introns from the gene
B- RNA polymerase inserting itself into the gene
C- RNA polymerase binding to a region near the gene, called the promoter
D- the joining together of exons to form the gene

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
