Are neurons haploids or diploids?

Which cell is considered a haploid cell? (has half the number of chromosomes?) Why?

3) At the completion of meiosis, how many sets of chromosomes does each daughter cell contain?     1     2     3     4   4) Imagine that a cell within a tissue is expressing a protein that leaves the cell and can “signal” to other cells. Which cells will respond?   A) Cells that are within range of the signaling molecule and have protein receptor that binds the signaling molecule   B) Cells that are within range of the signaling molecule   C) Cells that are within range of the signaling molecule and are expressing their own signaling molecules   D) Cells that are within range of the signaling molecule and are the same type of cell

What would happen to the chromosome number in gametes and offspring if ​gametes were formed by the mitotic process instead of the meiotic process?

What is the haploid and diploid chromosome number in the cell below?

When is a tetrad specifically formed?  Would it be found in a haploid or diploid cell?  What event caused the mosaic (mixed) appearance of the 2 inside chromatids?
