Okay Just A Simple Question

i've just been doin some revision on cells (i don't go to college yet but i am next year) and found out something that struck me.
when we damage cells, they have to be replaced right?
i did have 4 angelfish, a dominant pair and two smaller ones. the smaller ones were the same age as the other two etc but because they were being attacked over and over, they have become alot smaller.
is this because the cells have been working to replace the damaged ones instead of working on growth?
will my small angels start growing once they're fully healed?

ohh and btw, i removed the dominant pair so the little ones are on the mend

this is just a topic of curiosity as well lol

thanks

couldn't say for definate but it sounds plauisble

It is tough to say for sure. Some of the energy that would otherwise be toward gorwth would have to go to regeneration. But, if the fish were more apt to grow, it would replace those cells with a larger cell or more cells meaning that growth would just occur while regeneration. I'd actually put a little more weight on the fact that they are stressed from being picked on so much. That is a growth inhibitor as well. Finally, just like people and all other living creatures, sometimes individuals just grow slower and/or end up smaller. Such is life.

Definitely not: I may not be a full biology major but I can tell you that. What causes the growth retardation is the stress factor(release of chemicals into the system), together with a smaller share of the food: darwinian selection.

ahhh i get it now. thanks. i'd rather now than stick it in an exam lol

Hmm i wonder, do fish require hte use of mitosis(cell division for growth and regeneration) seeing as there being used for regenereation instead of growth, possibly, also id agree with the abovecomments
