Answer:
Graph A: Directional Selection
Graph B: Stabilizing Selection
Graph C: Disruptive Selection
Explanation:
Natural selection as a driving force of evolution cam be defined as a process that a population of organisms undergo in other to become adapted to an environment and survive to produce offspring that are fitter.
Thus, the following graphs represents the three types of natural selection:
Graph A: Directional Selection
Directional selection occurs when one extreme trait is favoured over others by selective pressures.
The graph shows that only one extreme trait is favoured as the population that survives seem to have majorly a particular extreme trait.
Graph B: Stabilizing Selection
In this type of natural selection, neither of the extreme traits are favoured by selective pressures. Therefore, intermediate trait become favoured over the other extreme traits.
Graph C: Disruptive Selection
Selective pressures works against the intermediate trait while both extreme trait at the spectrum are well favoured, which become more established in a population against the intermediate trait.
Channels with a low gradient
The transport of zebra mussels to the US took place involuntarily through the discharge of ballast water from European ships with contaminated cargo, in the 1980s, spreading across the Great Lakes region.
<h3 /><h3>Impacts on the environment</h3>
This freshwater mollusk can negatively impact the environment by filtering out algae that feed native species and clogging up water transport and storage systems.
Therefore, due to its high reproduction rate, zebra mussels spread rapidly and render water systems unusable, generating significant ecological and economic impacts.

Answer:
According to Coulomb's law, the magnitude of electrostatic force of attraction between two point charges is directly proportional to product of magnitudes of charges and inversely proportional to the square of the distance between them.
Mathematically, F = \frac{q_{1}q_{2}}{r^{2}}
where F = force
q_{1} = charge 1
q_{2} = charge 2
r = distance between the charges
Therefore, when distance is increase by four times then the force will decrease by a factor of 16 as force is inversely proportional to the square of distance.
