Answer:
The correct answers are "The population of birds with large beaks will increase on the island" and "The trait for large beaks will be passed on to future generations through natural selection".
Explanation:
Natural selection functions under the premise of survival of the fittest, where stressful situations such as lack of resources will select the organisms with advantageous traits. In this case, the decrease on seeds affected particularly the numbers of small, soft seeds over large, hard seeds. This stressful situation will select the finches with the advantageous trait of having large beaks, because they are able to feed from large, hard seeds. This trait will be passed on to future generations through natural selection, which eventually will result in the population of birds with large beaks will increase on the island.
Answer:
Taj Mahal is slowly losing its white color because of pollutants from vehicles and industries around it. It is a result of chemical weathering. Polluted air contains a large amount of nitrogen and sulfur oxide released from the industries in the area.
These chemical comes down with the rain and called acid rain. This acid rain reacts with the marble which is made up of calcium carbonate thereby turning the Taj Mahal yellow.
These environmental pollution cause the oxidation of marble constituents from which Taj Mahal is made up of and are responsible for the chemical weathering of Taj Mahal.
