The answer is B. This is called genetic shift. The pups with advantageous traits are able to survive until the age of reproduction hence able to pass their genes to the next generation. Few and fewer pups with disadvantageous traits will get to reproduce hence the allelic frequencies of the shark population will shift in favour of increased hunting efficiency.

What does the water cycle look like? what does the nitrogen cycle look like?

Yakvenalex [24]

The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration is called water cycle. The first picture is a picture of the water cycle.

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into various chemical forms as it circulates among the atmosphere and terrestrial and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
