hey I solved it like I assumed the starting was "x" so "x"-(21%ofx)=120 so --> x- 0.21x = 120 so we get 0.79x=120 therefore, x=120/0.79 which is equal to 151 cm3 approx. I hope you got the way I used :)- Lujain M.

because for parents to get a male child it should always be "XY" females always have XX chromosomes and males XY so obviously males will give the "Y" while females will be "X" "XX" and "XY" are sex cells not chromosomes :) I hope you got it ! :)- Lujain M.

yes it's A because the shoot "showed a response to gravity" which is negative because shoots always grow away from gravity while radicle always grows towards gravity :)- Lujain M.

Q 25 : the question is about shoot not radicle... and shoot responded away from gravity (negative geotropism) Q40: because green is the chlorophyll pigment..no chlorophyll-->no photosynthesis-->plants die ! :)- Lujain M.
