After a cell has become a haploid cell through meiosis, it becomes an individual by way of mitosis, since it has now had its correct number of chromosomes restored upon fertilization. Can a haploid cell itself go through meiosis? Is there any other fate of a haploid cell other than becoming an individual after fertlization? What about in plants? Thanks, I have searched everywhere and all examples of diagrams of cell reproduction are always with diploid cells, and nothing is said of haploid cells after they become haploid cells.

I know that H2O is bonded because O has 6 electrons on the last shell.. and the H2 has 2 electrons to share with O giving it 6 and H getting 2.

However, when I think about Ag2O I don't see how the shells can be filled.

Can any one explain this (without using valence electrons and the dot diagram thing?)

1: In a square pyramid the edge of the base is 24 inches, the slant height is 20 inches, and the altitude is 16 inches. Find the lateral area (the surface area of the triangular sides only).
850 sq. in
900 sq. in
960 sq. in
990 sq. in


2: In a square pyramid the edge of the base is 24 inches, the slant height is 20 inches, and the altitude is 16 inches. Find the total surface area (the surface area of all sides of the pyramid).
960 sq. in
1115 sq. in
1230 sq. in
1536 sq. in


3: In a square pyramid the edge of the base is 24 inches, the slant height is 20 inches, and the altitude is 16 inches. Find the volume.

I am a walking electricity bolt! Granted, I live in the desert but I mean nobody believes how this is affecting my life. I am terrified to touch practically anything. My car has turned into a monster I have learned to open and close the car doors with my feet, but when I turn on the ignition I get a pretty hard shock. I can't touch anything. I have tried anti-static sprays and carrying static sheets with me but no luck. This static is taking over my life and I need help to live normally again. Somebody please help!
