what was the answer of the mcq in which they asked when the male reproductive gamete enters a pollen tube in a plant

it was the ovule..
nd it wasnt "when it enters the pollen tube" it was "when is it released from the pollen tube"

 

[Anonymous-BLEH!]

both were ez. i think the down syndrome one was A, due to mutation in the chromosome of ova? i cant remember exactly.

i think the same but most of my friends said something else.... they said C i think.... dont quite remember right now... but i think A is the answer probably..

what is the oxygen nf magnesium ion content in a chloroplast??
oxgen high nd magnesium ion high or
oxygen low nd magnesium high
(please explain ur answer briefly)

Oxygen low

what is the oxygen nf magnesium ion content in a chloroplast??
oxgen high nd magnesium ion high or
oxygen low nd magnesium high
(please explain ur answer briefly)

and magnesium high. Oxygen was low as compared to other parts of cell because photosynthesis needs carbon dioxide. Magnesium was high because chloroplasts need magnesium to manufacture cholorophyll and carry photosynthesis

Both were high.. as it was day time as the question stated so there was active uptake of ions so magnessium ions were present..
and at day plant photosynthesise.. producing Oxygen.. so it was there..

Thats what i think :/
