Like eukaryotic cells, prokaryotic internal structures, such as those of eubacteria, are surrounded by a cytoplasmic membrane consisting mainly of phospholipids. However, the cell membrane of prokaryotes is less rigid than that of many eukaryotes. That’s because they lacksterols(except forMycoplasmath...

the organism can survive unfavorable conditions, including depletion of nutrients, water, and oxygen, or when the organism is exposed to extreme heat or toxic chemicals. The cyst can also protect protozoa outside the host since some parasitic protozoa are excreted from one host to infect the ...
The living components of the biosphere, also known as the biota, plays an integral role in providing us with the raw material we need to survive: food, fuel, and fiber. 4. Cleans the Earth of Toxic Substances The natural cycles of decomposition and biological modification, which take place ...
and irrigation systems is a potential threat to the environment. These techniques can place high demands on freshwater sources and have the potential for introducing toxic contaminants and excess nutrients into streams and rivers or promoting soil erosion.
