Some species of Sphingomonadaceae are known to degrade some aromatic compounds.This makes the bacteria of interest to environmental remediation. [8]The diverse metabolic capacity of genera within the Sphingomonadaceae family, such as Sphingobium, Novosphingobium, [a] and Sphingopyxis enable these genera to adapt to and be abundant in the presence of bisphenol A.
Within the diatoms (Bacillariophyta), harmful effects can be due to physical damage or to toxin production. Centric diatoms like Chaetoceros live as colonial chains of cells with long spines (setae) that can clog fish gills, causing their death.
Similar to plants, diatoms convert light energy to chemical energy by photosynthesis, but their chloroplasts were acquired in different ways. [ 19 ] Unusually for autotrophic organisms, diatoms possess a urea cycle , a feature that they share with animals , although this cycle is used to different metabolic ends in diatoms.
Stentor coeruleus, used in molecular biology (its genome has been sequenced), [5] and is studied as a model of single-cell regeneration.; Dictyostelium discoideum, used in molecular biology and genetics (its genome has been sequenced), and is studied as an example of cell communication, differentiation, and programmed cell death.
You might've thought zombies were the creation of science fiction writers, and while that may be true for human zombies, animals are a whole other story. 10 'zombie' animals that really exist Skip ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
This category lists some of the species that have become extinct due to human activity, whether intentionally or unintentionally. If a more specific reason is known, the species should also be assigned to a subcategory of Category:Species by threat. They may also need to be placed in Category:Extinctions since 1500.
It is the second largest of the human body and made of various bacteria, viruses, fungi and protozoa. [14] These organisms play an important role in oral and overall health. Anthony Van Leeuwenhoek was the first to view these organisms using a microscope he created. [ 14 ]
