Answer:
A.
Explanation:
Dark coloured moths will be better camouflaged and so better protected from predators. More of them will survive and reproduce, increasing the frequency of dark coloured genes.
Light coloured gene will provide less camouflage, those moths will be caught by predators more often and live to reproduce less. So the light coloured gene will decrease.
C. The cell took in another ancient prokaryotic cell, which began living inside it.
Answer:
The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".
Explanation:
In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.
