Was the height difference like max height of plant 2- max height of plant 1?

what about the meiosis MC question. the 3rd one i think. with the human females

was the answer producing 4 gametes bla bla bkla

No females produce 1

As far as I could remember, the bipedal footprint fossils were mainly identified as bipedal due to having a non-opposable big toe, allowing more efficient walking.

No females produce 1

dont they originaly produce 4 eggs or whatever and then only 1 gets the nutrients and the othe 4 die out.

First splits in 2, then 1 survives 1 dies, then the 1 survives splits 1 die 1 survive (egg). I think.

DNA microarray technology has been used to survey the p53 gene because a mutation of this gene is present in about 60% of all cancers. the position of a mutation in the p53 gene of a patient, patient x, who has breast cancer, can be determined.

No females produce 1

Do they produce one gamete or one functional gamete?

[gwood21]

they produce 4 daughter cells, 3 of them are polar bodies, 1 is an egg. not sure if these polar bodies are still called 'gametes' though

[simpak]

The fact that it specified 'female' was interesting.
It inferred to me that that answer was incorrect, and that the correct answer was I think B?

thats what i thought. they produce one functional gamete but the product at the beginning of meiosis is 4 gametes for each cell. i dnt remember anything of female only producing 1

There was 1 answer that was quite appropriate too. Something "it relies on..." was it spindle fibre contraction?

[biolstar]

q3 meiosis in human females
a. involves the separation of homologous chromosomes before DNA replication
b. relies on contraction of protein fibres in the spindles formed within cells
c. results in 4 gametes for each cell that undergoes the process
d. involves haploid cells giving rise to diploid cells

that question was pretty stupid i think. like could have been either of the two answers

[gwood21]

no but its not the contraction of spindle fibres that creates the movement, its the contraction of the proteins in the centromere of the chromosome. just another quality ambiguous question from VCAA
