platelets gather in the cut region
secrete thrombin
which converts soluble fibrogen to insoluble fibrin
which forms a mesh over the wound
which traps RBCs and more platelets
which forms a scab over the wound
uve got tht wrong.....platelets secrete thrombokinase which converts prothrombin to thrombin
den thrombin converts fibrinogen to fibrin which traps rbcs to form a scab...

it
s D that is 1.oo becuase recessive characterstic is always homozygous if it would be hetrozygous the dominant one will show its effect so it is always homozygous!
Furthermore, 1.oo probability means a 100% chance so D is the correct choice!!..:)
Thanks alot, but Ashiqbal did the explanation earlier! However your reply is appreciated

dis is the most easiest way to learn it:p
http://kidsgrowingstrong.com/germination
note:light is not necessary for seed germination
n the radicle is the embryonic root of the plant and the plumule is from where the shoot emerges
check this http://www.google.com.pk/imgres?um=...w=173&start=0&ndsp=15&ved=1t:429,r:3,s:0,i:75
