Cell Cultivations Balanced growth is defined as cultures undergoing balanced growth while maintaining a constant chemical composition balancing the growth while controlling the pH balancing the growth while changing the nutrient composition balancing the growth while controlling the temperature cultures undergoing balanced growth while maintaining a constant chemical composition balancing the growth while controlling the pH balancing the growth while changing the nutrient composition balancing the growth while controlling the temperature ANSWER DOWNLOAD EXAMIANS APP
Cell Cultivations The cell mass can be measured optically by determining the amount of light scattered by a suspension of cells. The measurements are usually at a wavelength of 600-700nm 400-500nm 300-400nm 500-600nm 600-700nm 400-500nm 300-400nm 500-600nm ANSWER DOWNLOAD EXAMIANS APP
Cell Cultivations The archaebacterium Halobacterium, an extreme halophile, and Sulfolobus, a thermoacidophile, can be cultured in the presence of antibiotics such as streptomycin and chloramphenicol because All of these they contain ether-linked isoprenoids in their plasma membrane they contain 80S, as opposed to 70S, ribosomes they lack murein in their cell wall All of these they contain ether-linked isoprenoids in their plasma membrane they contain 80S, as opposed to 70S, ribosomes they lack murein in their cell wall ANSWER DOWNLOAD EXAMIANS APP
