pashok25 [27]

Answer:

4. metabolism, growth, and evolution

Explanation:

Living organisms show different characteristics like respiration, movement, metabolism, growth, evolution, respiration, excretion, nutrition. Most of the microbes are microscopic and unicellular which means they are made up of only one cell but they are also living.

They perform three major types of activities like metabolism, growth, and evolution. This can be seen by culturing bacteria on suitable media. So in the medium, it can be observed that they consume the food present in media and extract energy from it through metabolic activities and are showing growth. All micro-organisms evolve due to mutation. So the correct answer is 4.

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species. Recently, these birds have been classified
taurus [48]

Answer:

The correct answer is A). The two forms are observed to interbreed successfully where their habitats overlap.

Explanation:

According to the biological species concept, the members in a population which interbreed with each other and produce viable offsprings comes under the same species. This classification does not involve morphology because even organisms having the same morphology can be of different species because they do not interbreed with each other in nature.

So here myrtle warbler and Audubon's warbler must be found interbreeding with each other and producing offsprings which have good survival rate and reproductive capability so this information might allowed scientists to reclassify these bird in the same species because only members of same species interbreed with each other. So the correct answer is A.
