Apple maggots are a type of fly native to North America. Prior to the introduction of the apple tree to North America, apple mag

gots fed from and laid their eggs on hawthorn trees. After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees. Adult apple maggots will only mate on the type of tree on which they were born.
What is the most likely consequence of the introduction of apple trees to apple maggots?

A.
Some apple maggots will undergo adaptive radiation to colonize many other types of trees besides the apple and hawthorn.
B.
Populations of apple maggots that mate on different trees could become reproductively isolated and eventually speciate.
C.
Apple maggots that are born on apple trees will be unable to reproduce and will eventually die out.
D.
Individual apple maggots will eventually learn to lay eggs on both hawthorn trees and apple trees.

Answer:

B

Explanation:

B is the most likely consequence because of the following facts we are told:

  • After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
  • Adult apple maggots will only mate on the type of tree on which they were born.

This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).

These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation.

Answer: B

Explanation:

Adult apple maggots mate on the type of tree on which they were born. Because apple trees were recently introduced, the adult maggots had to have been born on hawthorn trees, where apple maggots used to lay their eggs. Other apple maggots mate on apple trees. The two groups of maggots will not reproduce with each other because they prefer to mate on different trees. This type of reproductive isolation is called behavioral isolation, a difference in mating behavior that prevents organisms from reproducing with each other. This reproductive isolation will eventually result in speciation, or the creation of new species through physical separation.

What factors drive the movements of global air masses
maksim [4K]

Answer:

The 4 types of air masses are polar, tropical, continental and maritime. Their classification depends on their location where they are formed.

Explanation:

One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. The jet stream wind is often referred to as a steering wind. The troughs and ridges of the jet stream will help transport cold air toward lower latitudes and warm air toward high latitudes.

What physical health risks are directly associated with urban sprawl?​
spin [16.1K]

Answer:

The risks of various pollution and infections increase with urban sprawl.

Urban sprawl can be described as a condition in which the people from urban area migrate to low residential areas due to which the city starts to expand more in size.

During urban sprawl, more water contamination is likely to be caused as the water available cannot support such a large number of migration. There is not proper sewage system due to which contamination arise and cause sickness in the people. Also, these areas have more pollution due to traffic jam situations which causes sickness.
