The proportion of long-tailed squirrels may have increased due to increased food availability.
The statement has it that the percentage of long tailed increased also that the long tailed are better at jumping and balancing on trees.
The first option could is tempting but saying decrease in trees would not likely support the argument.
The last option has more sound options as more food availability may lead to population increment
Hope it helps....
Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. Hoped this helped!!!!. Also if you are trying to look for the formulas it should be online just type in stoichometry formulas.
The area is 23x20 which = 460 sq ft.
If each sq foot gets 1250 flakes per min, it gets 75,000 in an hour.
The whole lawn gets 34,500,000 flakes in one hour, which would weigh 75,900,000 mg.
This equals 75.9 kg
