 Cancer cells can survive without being attached to other cells or to a substratum. This feature contributes to their ability to ________.
   
   attach to healthy body cells.
   spread to other parts of the body.
   grow rapidly.
   contribute to an increased blood supply.

I am thinking grow rapidly. What do you all think? Also, here is another question:


 Intercalated disks are cell-cell junctions found between cardiac muscle cells. A feature of intercalated disks is a large number of gap junctions. This means ________.
   
   an extension of smooth endoplasmic reticulum goes through the gap junction, making it continuous from one cardiac muscle cell to the next.
   the plasma membrane encompasses multiple cardiac muscle cells.
   RNA from one cardiac muscle cell can be transported into an adjacent cell through the gap junction.
   water and small ions can readily pass from one cardiac muscle cell to the next.

What do you all think? I think water and small ions can readily pass...also, nucleotides, amino acids, etc. Please help. thanks!

While this property does help them grow rapidly, another correct answer is that this property helps the cancer spread to other parts of the body.

Correct.  Small molecule (~<1000 Da) can easily pass through gap junctions.

Im a 400Level student in Lagos state university Nigeria and im reviewing an article on cadmium positivity and cancer.I would be very grateful if anybody can be of help to me or better still if we can work together on this project.
It would help save the world as all edibles are packed in plastic containers which most time releaes cadmium into the food itself.

ANYBODY?

Cancer cells can survive without being attached to other cells or to a substratum. This feature contributes to their ability to ________.
   
   attach to healthy body cells.
   spread to other parts of the body.

While this property does help them grow rapidly, another correct answer is that this property helps the cancer spread to other parts of the body.

Isnt attachment to healthy body cells a more probable answer? The loss of anchorage dependancy of the cancerous cell and the lack of density dependant inhibition enables cancerous cells to stack on each other and other cells, enabling cell proliferation without attachment to other cells. Cancerous cells in benign tumour are localised and do not spread while metastasis only occurs in maglinant tumour (or for other cancerous cell type such as those which originates from the bone marrow, lymphatic system). And thus spreading to other parts of the body may not exactly be the answer..

I disagree, you are being asked how "survival without being attached to other cells" contributes to their ability to ________.

"spread to other parts of the body" is the correct answer, "attach to healthy body cells" would occur after the distribution. The question deals with survival of unattached cells not their ability to reattach to healthy cells after distribution.

[AhmedEzatAlzawalaty]

the correct answer is spread or metastasis.
