Answer: (1) photosynthesis occurred
Explanation: The photosynthesis process in cianobacteria changed the composition of earth's atmosphera, rising oxygen levels. This could be possible since photosynthesis used energy from the sun to produce energetic intermediaries to synthesize sugars, and as byproduct due to water photolisis, is oxygen.
The answer for the given question above would be TRUE. It is true that bacteria on a green salad <span>can create a food borne illness outbreak. In fact, based on some researches, bacteria found in salad is more dangerous compared to those found in meat. Hope this answers your question. </span>
The answer would be A. 500g because the candle would not lose mass despite being melted. Melting the candle is only a physical change and not a chemical change resulting in no change in the mass.
<span>microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes.
</span>FULL ANSWER<span>Archaebacteria, or archaeans, are single-celled organisms. Although they were first classified with bacteria, they have since earned their own category. While they have a simple structure much like bacteria, there are many differences. They have a unique type of rRNA that sets them apart from their fellow prokaryotes. Furthermore, they do not cause sickness in people.Archaebacteria are considered extremophiles because they live in a variety of harsh environments and can tolerate extreme conditions such as, acidity and salinity. They are divided into three main groups: crenarchaeota, euryarchaeota and korarchaeota.Crenarchaeota consist of hyperthermophiles and thermoacidophiles that thrive in very hot, cold or acidic environments. Euryarchaeota consist of halophiels and methanogens that thrive in salty and oxygen-free environments. For example, euyarchaeota often live inside in the guts of animals. Compared to other the other groups of archaebacteria, less is known about korarchaeota. Scientists do konw that they are thermophilic and live in hot springs.</span>
