The effects of sinkholes vary based on where and how they were formed.
When naturally formed on land, they will change the topography of the surroundings, cause nothing but minor issues, if any issue at all.
When formed on highly populated areas, though, they can cause a lot of damage to humans and properties in the region. Damage caused to the base of a building might be a very serious problem.
Toxic chemicals can also come up through sinkholes.
Answer:
Image result for How do solute concentrations affect the rate of osmosis within the cell?
Concentration gradient - The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent.
I think this is it^^^

Answer:
Alchemy
Explanation:
Alchemy is the believe that base metals such as a copper, lead etc can be transmuted into gold.
The alchemists were in search of a magical piece that would enable them to make gold from base metals. They called this magical stuff 'the Philosopher's Stone'.
Modern science has discovered that lead can be turned into gold,without applying the methods of alchemy. Nuclear transmutation in particle accelerators can indeed change one element into another.
Answer:
42.4%
Explanation:
5Fe2+(aq) + MnO4^- (aq) + 8H^+(aq)---------> 5Fe^3+(aq) + 4H2O(l) + Mn2+(aq)
Concentration of oxidizing agent =0.102M
Volume of oxidizing agent= 21.6ml
Amount of MnO4^- reacted= CV= 21.6ml/1000 × 0.102= 2.2 × 10^-3moles
From the balanced redox reaction equation
5 moles of Fe^2+ required 1 mole of MnO4^-
x moles of Fe^2+ will require 2.2 ×10^-3 moles of MnO4^-
x= 5×2.2×10^-3/1 = 11 ×10^-3moles of Fe^2+
Therefore, mass of Fe^2+ reacted = 11×10^-3 × 56= 616×10^-3g of Iron
% 0f iron present = 0.616/1.45 × 100= 42.4%
