1 diploid cell (2n) cell becomes 4 haploid (n) germ cells (eggs or sperm). During meiosis, chromosomes are replicated once in S phase (just like mitosis), but the cell divides twice. ... The result: chromosomes after meiosis are genetically unique and have combinations of DNA derived from both parents.
Answer:The electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. The electron transport chain is built up of peptides, enzymes, and other molecules

Answer:
Label A: Nucleus
Nucleus can be described as the organelle in which the DNA is enclosed. The nucleus is found in every eukaryotic cell.
Label B: Vacuole
Vacuole can be described as an organelle which is used to store material such as waste. Hence, vacuole is known to be the storage house of a cell.
Label C: Ribosomes
Ribosomes can be described as structures which are present usually on the rough endoplasmic reticulum. The process of translation occurs in the ribosomes and they are hence known to be the protein manufacturing units if a cell.
Label D: Centrioles
A centriole is a cylindrical organelle which is usually made up of the protein tubulin.
