Types of Safety Capacitors: 1  There are two major types of interference-suppression / AC line filter safety capacitors; namely, type X and type Y. The purpose of these capacitors is to reduce radio frequency interference and to ensure safety from shock and fire. In AC/DC (radios that do not use power transformers) radios where a line filter capacitor is connected between the hot and ground side of the power line, that capacitor is known as an across-the-line capacitor. 2  Across the line capacitors serve to keep RF noise disturbances from affecting the receiver.
Asexual Reproduction for Eukaryotes Eukaryotes use a complex method of cell division to duplicate their chromosomes. As we have learned, when a prokaryote divides, it duplicates its loop of DNA and divides into two cells. This works for prokaryotes, but eukaryotes are more complex, Eukaryotes have their DNA in chromosomes in a nucleus in the cell. Eukaryotes can also reproduce themselves by division, but they have a problem to solve.
Almost all multicellular eukaryotic organisms that undergo sexual reproduction use gametes, or sex cells, to create offspring. Since two parents are necessary to create individuals for the next generation of the species, gametes are typically haploid cells.
