Plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exists in bacterial cells, and they also occur in some eukaryotes. The genes carried in plasmids provide bacteria bacteria with genetic advantages, such as antibiotic resistance. To know whether the cell carry recombinant plasmids; only cells with a plasmid will reproduce and also the color of the colonies in E. coli plasmid recombination experiments allows scientists to distinguish colonies with recombinant plasmids from those without.
Answer:
b. glycolysis
Explanation:
Anaerobic glycolysis is a catabolic route used by many types of cells for the degradation of glucose in the absence of oxygen. That is, glucose is not completely oxidized to carbon dioxide and water, as is the case with aerobic glycolysis, but fermentative products are generated.
It is called anaerobic glycolysis since it takes place without the presence of oxygen, which in other cases functions as the final acceptor of electrons in the mitochondrial transport chain, where large amounts of energy are produced from the processing of glycolytic products.
I think stratus clouds indicate possible precipitation
Soil pH affects nutrients available for plant growth. In highly acidic soil, aluminum and manganese can become more available and more toxic to plant while calcium, phosphorus, and magnesium are less available to the plant. In highly alkaline soil, phosphorus and most micronutrients become less available.
