Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream or river, resulting in better water quality. [2]
Injuries while swimming are rare; self-rescue is usually easy but group assistance may be required to avoid long swims. Rapids that are at the lower or upper end of this difficulty range are designated Class III- or Class III+ respectively. Class IV: Advanced Intense, powerful but predictable rapids requiring precise boat handling in turbulent ...
An obligate aerobe is an organism that requires oxygen to grow. [1] Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. [1] [2] In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. [1]

It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of ...
The two-domain system is a biological classification by which all organisms in the tree of life are classified into two domains, Bacteria and Archaea. [ 1 ] [ 2 ] [ 3 ] It emerged from development of knowledge of archaea diversity and challenges the widely accepted three-domain system that classifies life into Bacteria, Archaea, and Eukarya . [ 4 ]
The scientific name of a species is a binomial or binomen, and comprises two Latin words, the first denoting the genus and the second denoting the species. [5] The scientific name of a subspecies is formed slightly differently in the different nomenclature codes.
