<span>LD
means lethal dose. LD50 is the amount of a material, administered at once to
cause the death of half (50%) of a group of test organisms. A test which shows that LD50 of a certain
chemical is 20 mg per kg means that 20 milligrams of that chemical for every 1
kilogram body weight of the test animal when administered in one dose, causes
the death of 50% of the test group.</span>
The stages of mitosis are:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase<span>
Prophase
This is when the </span><span>centrioles separate and move to opposing sides of the cell.
Metaphase
This is when the chromosomes line up in the center of the cell and become connected.
Anaphase
This is when the</span><span> "sister" chromatids separate into individual chromosomes and are pulled apart.
Telophase
This is the last phase of mitosis, when chromosomes gather at opposite ends of the cell and new nuclear membranes form.
The answer is metaphase, because that is when the chromatids line up in the center of the cell.
