Gametes have half the number of chromosomes that most cells in the organism have. Most human cells have 46 chromosomes, but eggs and sperm have 23 chromosomes each.

Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
The reproductive cells of an organism each contribute half of the required genetic material to create the offspring. This means that each reproductive cell has 1n, while the organism has 2n chromosomes.
nothing, the nucleus just relaxes to a lower energy state that is more stable
During meiosis I, each nucleus will have half the number of chromosomes as the original parent cell. This is because meiosis I involves the separation of homologous chromosomes, resulting in two daughter cells with a haploid number of chromosomes.
Yes, that's correct. The number of chromosomes in a nucleus is specific to each species and can vary significantly. For example, humans have 46 chromosomes in each nucleus, while dogs have 78, and fruit flies have 8.
It varies from species to species. The human nucleus contains 46 chromosomes.
During animal mitosis, each nucleus contains a diploid number of chromosomes. This means that each nucleus in the cell will typically have two sets of chromosomes, with one set inherited from each parent. In humans, for example, this would mean that each nucleus contains 46 chromosomes (23 pairs) during mitosis.
After DNA duplicates, there are twice the number of chromosomes present in the nucleus.
The number of chromosomes is independent of where in the body a given cell is located. It depends instead on the animal in question. For example, a human has 46 chromosomes in each cell that has a nucleus.

Each new nucleus in Telophase 1 contains a haploid number of chromosomes. This means that each nucleus will have half the number of chromosomes as the original parent cell.
The number of chromosomes in the nucleus before mitosis is dependent on the species. The exact number is called the ploidy of the animal.
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
No, 29 chromosomes is not a normal number for a female. Typically, females have 46 chromosomes, consisting of two copies of 23 chromosomes.
The diploid number of chromosomes in humans is 46. This is identified by counting the number of chromosomes in a cell's nucleus, which contains two sets of chromosomes - one set from each parent.
