Polygenic traits, traits determined by more than one gene, often have phenotypes that are distributed on a bell curve. occurs when one end of the bell curve is better adapted to the environment than the other. Natural selection disrupts the because one allele of a gene is preferred over another, changing the allele frequencies over time.
The development of different species without the influence of geographical separation is called speciation.
Respond to the following based on your reading.

A new species forms because of the formation of a mountain that divides one population into two. What type of speciation is this?
The bell curve in polygenic traits is becoming narrower over time. What type of selection is occurring?
What are the five conditions impacting the Hardy-Weinberg equilibrium?
How does natural selection impact single-gene traits?
What does the allele frequency have to total in the Hardy-Weinberg equilibrium?

"a.) well–developed vascular system."

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.
