A means of water erosion would not be C. natural water springs. Erosion occurs when water or wind removes rock, dissolved material, and soil from one location to another. All the other options describe water moving from one location to another, which accurately describes what erosion does.
Answer:
1. Kingdom Protista
2. Kingdom Eubacteria
3. Kingdom Archaeabacteria
Explanation:
1. Kingdom Protista is one of the the six kingdoms. It consists of organisms called PROTISTS that are eukaryotic i.e. possess a membrane-bound nucleus and mostly single-celled (unicellular). Protists are eukaryotic organisms like plants, animals and fungi but their characteristics do not fit into any of these three eukaryptic groups. Protists include; algae, amoeba, etc.
2. Kingdom Eubacteria, as their name implies, are known as true bacteria. The constituent organisms of this kingdom are prokaryotic i.e. lack a membrane-bound nucleus and single-celled (unicellular). They possess a cell wall, in addition to their cell membrane, that is made up of PEPTIDOGLYCAN. Examples of organisms in this kingdom are Streptococcus, Bacillus etc.
3. Kingdom Archaebacteria were once grouped together with the true bacteria as kingdom Monera but were split because of their obvious differing characteristics. Archeans are single-celled prokaryotic organisms characterized majorly by their ability to live and thrive in extreme environmental conditions e.g hot conditions, anoxia conditions (no oxygen).
The answer is D because it contains transitional fossils
66 million years ago at the end of Cretaceous period. It was called The Cretaceous- Palestine extinction event.
While studying bases in the DNA of organisms, Chargaff discovered that the ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.
