dammit you beat me to it!

I did the artificial ones both increase genetic diversity and limit them (that was my 'discussion'). Cloning just decreases. I'm not saying that's correct, just what I wrote.

Yeh i said that artificial insemination/pollination, transgenic species, hybridisation, cloning limit genetic diversity, but i also said that all of them (apart from cloning) could increase genetic diversity if used in the right way. (i explained obviosuly with examples)

not bad

that macrophage tho

looked like googly eyes

They're trolling us. I swear. The exam makers are high.

Wasn't a macrophage tho

ur right woopsie

I believe 17 is B

As cytotoxic T cells do not release cytokine. In biology in focus it says th helper cells release cytokine as a form of interaction when the macrophage presents the antigen.

Cytokines are the chemicals released by T-cells and they do more than just that, like prompting B-cells to clone and differentiate.

Really, this is another shit MC question, could technically be either one. But I think the most obvious is C.

Why would it not be C? I can understand thinking it's B, and I can't prove that B is wrong, but I don't believe you can prove C is wrong at all.

Haha exactly right! Thats the problem. You can prove so many questions that may seem wrong. I swear...dont know what bostes was drinking this year.

Yeah it's ridiculous. I hope most of them they are forced to accept more than 1 answer.

It's confusing tbh. Pretty much all leukocytes produce cytokines, and usually a macrophage activates a t helper cell and then the helper tcell activates the macrophages if it's an appropriate immune response. Unless you think about CD8 cells. Pretty poor question.

I think it's a cytotoxic T cell.

 

[Khan.Paki]

Really? That sucks. I never learnt that cytotoxic T cells could release cytokines. Oh well.

Yeah... I don't think it would be a cytotoxic T cell. Cytokines do not equal cytotoxins (chemicals that cytotoxic cells produce), right?


Anyway I truly believe it's C because that it the answer you cannot correctly argue against. The other answers you can all argue it's not the answer.

Plus...

I think its a cytotoxic T cell!

 

[BlueGas]

I think its a cytotoxic T cell!

I doubt it, I put B but I also think that's wrong.

I think it's not D because it's showing the "interaction" rather than the "action" of the cells, and I think it's not B because the wording is weird, "activation of a macrophage", it's actually the opposite, a macrophage activates a T-helper cell which then stimulates the growth of the B-cells.

I'm 99.5% sure it's C. The diagram above is literally where they got that picture/diagram in the test.

100% sure it's C b/c the antibodies on the B cell is a dead giveaway...cannot be more than 1 possible answer

Screenie the question. I will decide
