Diane Dodd took one species of fruit flies split it into two groups. She raised one on maltose based food and the other on a starch based food for several generations (both are stressful and the populations took a long time to establish). At the end of the experiment she mixed the flies to see if they would interbreed. The maltose raised flies showed a strong preference for other maltose rasied flies whereas the starch flies showed a strong preference for starch. Which of the following are a=true b=false regarding this experiment.
A. This is a laboratory simulation of sympatric speciation
B. If Dr. Dodd had transferred a few flies between each colony every generation, speciation would be less likely.

answer: 2

explanation:

yes

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.
