Allosteric regulation occurs at these points where the concentration of the substrate and/or products is important for the activation and inhibition of the enzyme.
In the apple maggot fly, the frequency of certain alleles increases steadily as one goes from North to South. This is an example of: Sympatric speciation.
Sympatric speciation is observed when there are no physical barriers which prevent any members of a species from mating with another, and all members are in close contact to one another. A new species, possibly established on a distinct food source or trait seems to develop instinctively.
The example of apple maggot fly supports a model for sympatric speciation in progress. Hawthorn is the native host for the apple maggot fly in North America. However, in the mid-1800s, a new population developed on introduced, domesticated apple.

The answer is A ( No, the water looks clear but it may contain harmful bacteria or high levels of harmful chemicals in the water.)
Explanation:
Since urban areas feature high concentrations of people, they are also more deadly during natural disasters. If climate change leads to more frequent and intense storms and floods, high-density population centers will be among the most exposed.
