The study of e. coli led scientists to new experimental designs for studying operons. how did scientists begin studying operons? they began to study cell division of cells under a microscope to determine how operons worked. they began testing different chemicals on e. coli to determine the number of operons present. they began reading the genome sequence of organisms to determine the number and organization of operons.

1. a tropical dry forest carries out more rapid nutrient cycling

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.
