Imagine that you discover a microbial deep-sea organism that can derive energy from (inorganic) hydrogen gas (h2). in addition, this microbe can synthesize organic compounds from carbon-containing inorganic molecules in the ocean. this microbe is a:

Microorganisms are involved in each of the following processes excepta. smog production.b. food production.c. infection.d. o2 production.e. decomposition of organic material.

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.

Why has two different alleles for the same trait?
