Answer:
Option 3, Chromatids remain attached to one another until anaphase
Explanation:
Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.
Hence, option 3 is correct

Answer:
200 meters
Explanation:
A kilometer is 1,000 meter. 0.2 x 1,000 is 200 meters.
You can also think of it this way, 0.2 is 1/5. We need to find 1/5 of a kilometer. We know the conversion is 1,000 meters/kilometer. 1,000/5 is 200. Therefore you must walk 200 meters to hatch the egg.
In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.
