In mitosis, when do the sister chromatids align with centrosomes in the cells?
USPshnik [31]

Answer:

The answer is probably B. Metaphase

Explanation:

In mitosis, the sister chromatids align in the "center" of the cell as the centrosomes are at the poles of the cell. They do this, moving on to the next phase Anaphase - where they will eventually split. Interphase isn't part of mitosis - it describes the period in which the cell is just growing and copying DNA.  If you textbook says it is, then thats ok, sometimes its included as part of it (even though technically its not).

Which of the above molecules would be least soluble in water?<br><br>(See attached image)​
weqwewe [10]

C

Explanation:

Molecule C would be least soluble in water because it is not a polar compound/molecule. It also lacks any unit that can combine with water to form a good hydrogen bond.

  • The general rule of solubility is that like dissolves likes.
  • Polar molecules will only dissolve in polar solvent.
  • Water is a polar solvent with hydrogen bonds in them.
  • Hydrocarbons typically have weak london dispersion forces between them and they are not polar.
  • Other compounds have functional groups that can form hydrogen bond with water.
