Did anyone else find that all the multiple choice questions harder than usual?

yes they were normally thy are easy marks :frown:

ok will these get me 1 mark for the last question ?
1)Reintroduce the species far away from each other to reduce the competition
2) Introducing a new prey will help to increase their survival chances

is it interphase or cytokinesis?

the paper was tooo long no time i swear

do plants cells contain centrioles then?

No, plant cells lack centrioles. Don't know how they organise their spindles.

for the question was about whether the cell is in interphase or cytokinesis, a lot of people are saying that it is interphase because the chromosomes were not visible which means it must be in interphase

however, if u look in the textbook, it states that the chromosomes unravel during telophase so during cytokinesis they are invisible so thats why i personally believe it is cytokinesis

correct me guys, in the taxonamy question I wrote about that organisms are grouped according to their morphology and molecular phylogency.
also the question of the difference between totipotent and pluripotent, i wrote totipotent all genes are switched on while pluripotent some are on and off.also i wrote totipotent can give rise to all 216 cell types and pluripotent to all types but fewer the totipoten.is that right because i didnt stated extra embyrionic cells.

Except the q was which stage of the cell cycle it is undergoing...Cytokinesis is just the splitting of the cytoplasm, not a stage of the cycle. It must be interphase.

No, cytokinesis is just the splitting of the cytoplasm and is part of late telophase. The q asked which stage of the cell cycle so it must be interphase

WHat about the WIlliam WIthering q? I know he made the Digitalis soup but is that the same as isolating digitalis? :confused:

Yes and i remember those 2 cells were the only ones that were attached together, all others with a nucleus was seperate. Hopefully both interphase and cytokinesis will be accepted provided a valid explanation is given.

you might get 1 marks for the toti and pluri questions and I put the same answer for the taxonomy question, that is correct but i'm unsure if that will give us the full 2 marks :s

2 ticks and a cross in the box where it said he tested on healthy individuals

Cytokinesis is very much a part of the cell cycle mate.

For the naming of the other 2 domains if i put bacteria/ prokaryote would i get the mark?
