I need help for d.

Shadow:

I'm pretty sure the major distinction between cancerous and regular cells is that the former does rapid growth, which would point to the distinction in time in favor of the cancerous chicken.

silvernight269:

Sorry. For d, I can answer the 1st question. I need help on the second. Should’ve been more specific. My bad.

Sazzie:

Invasiveness—Normal cells listen to signals from neighboring cells and stop growing when they encroach on nearby tissues (something called contact inhibition.) Cancer cells ignore these cells and invade nearby tissues. Benign (non-cancerous) tumors have a fibrous capsule

Shadow:

This sounds like the article for you.

silvernight269:

......

Shadow:

hmm nothing on stages. I'll keep looking

Shadow:

https://www.cyclacel.com/research_science_cell-cycle.shtml "Genetic mutations causing the malfunction or absence of one or more of the regulatory proteins at cell cycle checkpoints can result in the "molecular switch" being turned permanently on, permitting uncontrolled multiplication of the cell, leading to carcinogenesis, or tumor development." For further info on the cycle, it's in the bottom paragraph.

silvernight269:

I see what that means. Is there another explanation?

Shadow:

Like more differences? I don't know. This is a good example though.

Shadow:

I took biology 4+ years ago so this isn't really my area. @Vocaloid may know of something

silvernight269:

Sorry

Sazzie:

Shadow trynna sound smart....lowkey you read online...

silvernight269:

Vocaloid is busy

Shadow:

Something to look into would be how cells can tell when they bump into other cells, and would then thus stop dividing. So this would likely be another mutation where the cells don't know to stop when they are bumping into other cells.

silvernight269:

I think it’s supposed to be based on the data that we are given

Shadow:

Lol, just say they grow faster then.

Shadow:

Look at the times for each cell stage

silvernight269:

Cancer cells?

Shadow:

By the way you are missing two answers for c

silvernight269:

??

silvernight269:

Would it be interphase and prophase?

silvernight269:

Shadow, would regular cells grow faster or cancer cells?

Shadow:

look at the graphs and see which ones had smaller numbers in the cancer row than the normal cell row

silvernight269:

Prophase and telaphase

silvernight269:

Ok so I guess that’s a yes, and what about my 2nd question?

Shadow:

That's mitosis right, cell division. What is different? They took less time in blah, blah, and blah stage.

silvernight269:

Yes
