The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro
DaniilM [7]

Answer:

The correct answer to the question is: the level of liquid in Side A will rise.

Explanation:

  • Sucrose is formed of two molecules of glucose but the membrane is impermeable to it.
  • The given membrane is said to be permeable to water and glucose.
  • Through a semi-permeable membrane, molecules tend to move from a region where its concentration is high to another region where its concentration is low by the process of diffusion until its concentration in the two regions becomes equal. This phenomenon is known as Osmosis.
  • Concentration gradient of a molecule can be defined as the difference in the concentration of the molecule in two different regions separated by a semi-permeable membrane.
  • Considering glucose, the concentration of glucose is low in side A (1M) and high in side B (2M), so it will tend to move from side B to side A down its concentration gradient.
  • Considering sucrose, although its concentration is high in side A (2M) but low in side B (1M), it is unable to move as the membrane is impermeable to it.
  • Water tend to move from a region where the concentration of solute is low (or water concentration is high) to a region where the concentration of solute is high (or water concentration is low).
  • Due to the movement of glucose from side B to side A, the concentration of total solute concentration becomes high in side A as compared to side B. Therefore, water would move from side B to side A.
  • Hence the level of liquid in Side A will rise after sometime.

Can you please help me!? ​

Answer:

You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.

Explanation:

I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.
