You analyze a sample of Martian soil and determine there are microscopic, unicellular organisms that possess a nucleus, cannot p
hotosynthesize, and are heterotrophs. You can be reasonably certain that these are very similar to members of the: A. archaea B. algae C. fungi D. bacteria E. plants
In the given question, the characteristics given are:
1. Nucleus is present: confirms that the organism is a eukaryote as prokaryotic do not possess nucleus therefore the organism is neither bacteria nor archaea.
2. Do not perform photosynthesis therefore the organism is neither a plant nor algae as both are photosynthetic.
3. Is heterotrophic: the fungi are heterotrophic as its mode of nutrition that is they obtain the nutrients from the external environment.
The answer would be transitional forms like Archaeopteryx make
available DNA confirmation that demonstrates how organisms are related. Transitional
fossils establish the middle forms that happened over the evolutionary
trail taken by a single genus. A case in point of a transitional fossil is
archaeopteryx, which relates the evolution of dinosaurs (from jaws and claws)
to birds (feathers).
