Which cell create antibody-producing plasma cells?

i thought it was B cell, but the answer says it's cytotoxic T cells. (it doesn't give explanation) - can anyone clarify this? i googled it too, but am still confused....

And

"Although entropy continually increases within the universe as a whole, developing organisms gradually become more organized. Which of the following are these organisms capable of doing to aid this process?"
a) using external sources of energy
b) creating energy.

I thought it was (a) because that's what autotrophs do w/ sunlight energy... But the answer says it's (b).. Why?? Isn't this against thermodynamics law?

Thanks

cytotoxic t-cells through the release of interleukins can also stimulate the proliferation of B-cells and plasma cells etc

don't dwell on this one, i think you have the correct logic, don't dwell on the wording. DAT doesn't trip you up like that.

Energy is the main source of order in all living organisms so to aid this increase in entropy aka disorder organisms must input energy to organize themselves and their biological systems~!
