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.

It’s the control group.
The reason why is because the experimental group is the group in which they are experimenting with while the control group isn’t receiving any experimentation
Answer:
They would be a damage of cells because homeostasis regulate the internal body environment so as to maintain a steady state to provide optimum conditions for normal and efficient functioning of the body cells.
Arwin in 1856 proved that all pigeon breeds do originate from the Rock Dove and through a process of regression you can recreate the Rock Dove, the ancestor of all pigeon breeds. Hopefully that helped
The formula for the volume of a cone is V=(1/3)πr^2h, where V is volume, r is radius, and h is height. Plug in and solve:
V=(1/3)π7^2(27)
V=49(9)π
V=441π
V=1385.4412cm^3
Hope this helps!!
