It’s cool that you found that! You can try identifying it by its luster, color, breakage, etc, Try getting a piece of paper or something, scrap it on the paper, and see what it leaves behind. That’s a way many scientists identify rocks/crystals. You can also google types of rocks and see if you find a match. You always need to look at its color, as the color is the most distinctive feature of a rock. If you’ve since all of these things and your very serious about it, you can try calling somewhere or someone who would know (like a scientist who studies rocks).

If an organism has 8 chromosomes in each of its sperm cells, how many chromosomes would you expect to find in its liver cells?
mafiozo [28]

Answer:

The correct answer would be - 16 chromosomes or 8 chromosome pairs per cell.

Explanation:

In the body of an organism, all the somatic cells have the same number of chromosomes irrespective of their location in the body which is 2n or diploid. Liver cells would also have 2n number of chromosomes. The diploid number of cells are produced by the mitosis type of cell division or by fusing the sex cell that are egg cells and sperm cells. These sex cells are haploid of n number of cells or haploid.

If a sex cell as given in question sperm cells have 8 chromosomes then the liver cell would be 2n because sex cells after forming a zygote develooped to all other somatic cells including liver cells.

Sex cell = n = 8 chromosomes

liver cell - 2n = 2×8 = 16 chromosomes.
