Which of the following adaptations will probably develop most rapidly?
Paraphin [41]

Answer:

Mimicry

Explanation:

In mimicry, species evolve to resemble other species; in Müllerian mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defences in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight.

Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects.

Which of the following is NOT a property of life?A) Organisms take in energy and use it to perform all of life's activities.B) O
Blababa [14]

The correct answer is C. Populations of organisms rarely change over time

Explanation:

In biology, living organisms differ from non-living ones according to different features, this includes the ability to replicate or reproduce sexually or asexually; the metabolization of energy to different activities such as growth or reproduction; a complex system that allows them to live and the ability to adapt to the environment. This last idea implies organisms and populations of them change over time according to the environment and therefore the one that is not a property of life is that "populations of organisms rarely change over time".
