Which of the following are voltage sources
​

A voltage source is a two-terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source. If this isn’t the answer I’m sorry but you didn’t give answer choices

Meiosis is a type of cell division in which a cell divides twice to produce four identical daughter cells each with a haploid number of chromosomes. The result of meiosis is four identical daughter cells each with half the number of chromosomes as the parent cell.

Explanation: There are basically two types of cell division: Mitosis and meiosis. Mitosis is a process in which a cell divides to produce two identical daughter cells each with the same number of chromosomes as the parent cell while meiosis is a process in which a cell divides twice to produce four identical daughter cells each with half the number of chromosomes as the parent cell. Meiosis occurs in sex cells or gametes (sperm and egg). This produces gametes with haploid chromosomes of chromosomes (23 chromosomes). Mitosis occurs in somatic or body cells resulting in cells with diploid number of chromosomes or 23 pairs of chromosomes or a total of 46 chromosomes.
