Answer:
Metaphase ⇒ Chromosomes line up in the middle of the cell
Prophase ⇒ DNA condenses to form chromosomes
Anaphase ⇒ Each chromosome separates and moves to opposite ends of the cell
Telophase ⇒ Nuclear membranes form around each set of chromosomes
Answer: To have enough DNA for each gamete, the DNA in the germ cell must be <u>Doubled (x2).</u>

<span>The fluid flows through the interventricular foramen into the third ventricle, is augmented by fluid formed by the choroid plexus of this ventricle, and passes through the cerebral aqueduct to the fourth ventricle, which also possesses a choroid plexus. The CSF from all theses sources , as well as any formed in the central canal of the spinal cord, escapes from the fourth ventricle into the subarachnoid space through the median aperture and lateral aperture.</span>
<span>Meiosis is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.This process occurs in all sexually reproducing single-celled and multicellular eukaryotes, including animals, plants, and fungi. Errors in meiosis resulting in aneuploidy are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilitiesdiploid two copies of each type of chromosome (2N)
zygote
cell produced by fusion of a male gamete and female gamete (sperm and egg cells)
haploid
individual with one copy of each chromosome. also what the gametes are like when a diploid nucleus undergoes meiosis. (N)
genome
complete set of genetic information in the haploid set of chromosomes
homologous chromosomes
chromosomes that have the same arrangement of genetic loci, identical in visible structure and pair during meiosis, each member is called a homolog.</span>
Andrew Knoll's idea about prokaryotic metabolism from fundamental ecological circuity of life the bacteria but not the mammals, underpin the long-term and efficient functioning of the biosphere, it relates to the nitrogen cycle because of the bacteria is not emitting any nitrogen at all.
