If two whales of maximum length mated, the selection in this case would be?
IceJOKER [234]

Hi!


The selection in this case would be natural selection.


Natural selection is a process that involves organisms with favorable characteristics having a higher chance of reproductive success, and passing on their traits onto the offspring. This process, as opposed to artificial selection, does not involve human intervention and is a natural phenomenon.


In our case, whales with maximum length (the favorable trait) are mating on accord of their own, without external factors governing the process; hence, the selection is natural.


Hope it helps!

Which defines background extinction?
victus00 [196]

Answer:

<em>The correct option is D) the natural extinction rate</em>

Extinction can be described as a process due to which species get removed from the world.

Background extinction can be described as the standard rate of extinction of organisms of a species due to ecological or environmental factors. It is a low-level type of extinction which occurs over a long period of time. It can be described as the natural extinction rate of individual organisms. Hence, option D best describes the natural phenomenon of background extinction.
