Explain why the terms "heterozygous dominant" and " heterozygous recessive" are never used?

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
