Question 9, when it was asking about why the males show more courtship behavior towards longer snakes :confused:
more unsaturated fatty acids detected be male snake and it related it to a longer snake secreting those acids.

ill start:
Question 1
a) Centromer
b) centromere splits as spindles contract pulling chromatids to opposite poles, producing 2 identical cells.
c) different alleles
d) chromosomes not replicated into sister chromatids as figure 2 is prior to synthesis. ( I put only contains sister chromatids idk)
e) 3 chromosomes- 1 from each homologus pair( ie. one long,1 medium and one short)

Question 2
a)similar organisms capable of breeding to produce fertile offspring belong to the same gene pool
b) groups withing larger groups with no overlap
c) groups based on evolutionary relationships
d)cant remember

some one please quote me and continue...

Hmm....I'm kinda surprised at the response to the exam. My prediction of 6 marker was true!

Few questions

Why was diffusion higher when water from tracheoles in insects was removed? Higher SA:VR?

Species diversity was 6 something?

Tick boxes: quaternary structure was haemoglobin? Nitrogen present in starch and cellulose? Can't remember other box...


Posted from TSR Mobile
diffusion is more rapid in air than in water!

what was the number of N and n for the species diversity question in order to work it out?? I got 0.1 definitely have done something wrong...

2d was species diversity increasing question,

Greater number of habitats/ niches
Greater variety of food sources
Greater number of species, and number of individuals survive

Something like that...

I think he was on about the one below that one.

I put, put filter paper without the lipids.
Ah. Same.

diffusion through membrane faster when gas dissolved in water (thats why alveoli are moist)
