Cyanobacteria also known as one of the first organism on earth are responsible for producing nearly 80% of the oxygen on earth.
Answer:
recombination occurs during meiosis in homologous chromosomes
Answer:
Chromatin
Explanation:
I'm pretty sure this is the answer, let me know if it isn't.
The common bile duct is formed by the union of the cystic duct and the common hepatic duct.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unit to form single cell for sexual reproduction. During reproduction, when the sperm and egg unit to form a single cell, the number of chromosome is restored in the offspring.
Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
