Question

What do the permafrost and peat bogs have in common? They provide examples of what happens when microbial saprobes are inhibited These are both ecosystems that are dominated by extremophile Archaeans These are two of the ecosystems with the highest microbial diversity in the world Which of the below characteristics of living things do viruses NOT possess? Evolution by natural selection Metabolism Genetic material Proteins Hypotheses about the abiotic origin of life are still being tested and are somewhat speculative, which therefore means that the theory of evolution by natural selection is equally speculative. True False

Explanation / Answer

These are ecosystems that are dominated by extremophiles Archean. Permafrost is condition where temperature remain subzero for long period thus only Archean can grow similarly peat bogs grow in nutrients deficient acidic soil and in this condition acidophilic Archean can grow. In both conditions metabolic rates of organisms are slow.

Both ecosystems have low biodiversity.

4)viruses do not possess metabolism. This option is right answer.

Evolution by natural selection is exhibited by only those organisms which having their metabolism. Hence it is not right option.

Genetic material and protein found in viruses hence both options are wrong.

5) False because theory of natural selection proposed earlier and proved by different types of evidences, thus this theory is not speculative.
