When the pair is Tt, T is expressed and when the pair is tt, t is expressed. hence b and c both are correct. but genes are present in chromosomes, not the chromosomes in the gene. hence a is incorrect.
Which of the following is anhydride of perchloric acid?
Question no 16 can you give me the structure of anhydride of perchloric acid
As the particles have different velocities their masses are different. Considering this as a SUPER ELASTIC COLLISON we get. m1v1=m2v2, as,v1:v2=8:1 ;hence m1:m2=1:8, also nuclear density is constant, let it be=D,let the volume of the particles be v1 and v2 respectively. now, v1:v2=m1/D:m2/D=1:8, as volume of a sphere=4/3 pie Rcube, R1cube:R2cube=1:8; hence,R1:R2=1:2
