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.
Sexual reproduction in Eukaryotes. In most eukaryotes, especially higher animals, individuals normally exhibit one or two sex phenotypes; female or male. In such species, females produce the female gametes-eggs, ovules or macrospores and males produce the male gamets-sperm, pollen or microsproes.
