30 Points! Identify the first step of DNA transcription below.
O The RNA polymerase binds to a DNA molecule and separates its two strands.
O Specific base sequences on the DNA molecule signal where the RNA polymerase should begin transcribing a
section of mRNA.
O Other base sequences on the DNA then signal that the new mRNA molecule is complete, and transcription
stops.
O One strand of the DNA serves as a template to assemble nucleotides together into a complementary mRNA
strand.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
