Answer:
"If two populations of cells that are expressing different levels of P-cadherin are mixed and the cells sort out into a ball of cells, the cells expressing the lower levels of P-cadherin will end up on the inside of the ball."
Answer:
False
Explanation:
This is because the level of expression of Cadherin on cell surface membrane determines the sorting out of cells when mixed or adhere together. Evidently if two cells expressing the the same P-cadherin but at different levels are mixed, cells expressing low levels which populated the outer cells membrane(check the attachments( diagram. B) are generally sorted out, while cells with higher levels are inside the ball of cells.(check the attachments diagramme B.).
This display may attributed to (1) differences in adhesive activity of low levels to high levels, of P-cadherin and(b) to the differences in the levels of affinity of the Cadherin to the cell membrane of the two cells.
However, if the cells contains same levels but of different different P-cadherin, the diagramme A , in the attachments gives the answer.
