Imagine a population of mice that is either long-tailed or short-tailed. If a forest fire happened to
kill most of the mice with short-tails, the population of long-tailed mice would increase. This
evolution would be contributed to

selective breeding
genetic engineering
human impact
environmental factors

environmental factors

Explanation:

this is because forest fires are usually because of the rise in temerature

selective breeding

Explanation:

because only long tailed mice population dominating in forest, as short tailed mice are cullied in forest.

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.
