Answer:
Because when they brought the cows back the Autumn Buttercup began to thrive. They took the cows out of the pasture thinking that the Autumn Buttercup would grow better. They noticed that the Autumn Buttercup was thriving in a field nearby where there were cows grazing.
a.) When the cows ate the grass in the fields, it made the grass shorter that the mice couldn't live there and be safe from their predators.
b.) When the cows walk on the soggy ground it pushes up the soil on the sides of the cow print where the buttercup like to grow and not directly in the soggy soil.
Nature has been developing its habitats for thousands and thousands of years. In time there is a balance where there aren't too many plants and animals, but enough food for each. When there is a change in any habitat and something is taken out or introduces, then it changes the population of different species where it may deplet one type of species and let another type of species overpopulate. It can cause species to extinct. It will take nature hundredsof years to find balance again.
Explanation:
Answer:
D) Dispersion; dispersion
Explanation:
Pentane or heptane are non-polar molecules so both of the , dispersion or london force exists as intermolecular force exists among molecules of pentane or heptane . So these bonds needs to be broken and dispersion interaction takes place between molecules of pentane and heptane. Dispersion interaction of AB type is stronger than AA or BB type.
Answer: Energy released during the reaction is 0,299 kcal
Explanation: ΔH is the amount of energy released when 1 mol of C3H8 reacts, but there is no 1 mol but less, 3.40 x 10^20 molecules
Using Avogadro's number is possible to calculate the number of moles
The product of the mol number and ΔH is the energy released during the reaction
