The alveoli. These little air sacs are found on the end of the bronchioles and are the place where oxygen enters the blood and the carbon dioxide leaves.
Answer:
D. Changes in the environment changed each morph's ability to evade predation in different ways.
Explanation:
The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.
When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.
Therefore, option D is best option.

Answer:
Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?
Explanation:
Based on the information provided within the question it can be said that the question that would best bring about investigation onto this hypothesis would be "Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?" as it brings up the most important topic, of how could RNA have developed into DNA?
