Answer:
A homozygous recessive pea plant would have genotype rr and the heterozygous plant would have genotype Rr. So after the crossing between these two individuals occurs the two offspring produced would be heterozygous and the other two would be homozygous recessive.
R r
r Rr rr
r Rr rr
Therefore the genotype ratio would be 1:1 and the phenotypic ratio would also be 1:1 in the F1 generation because half would be round and half would be wrinkled.
All starfish limbs are designed to do have the same function, which means that in case a limb is severed, the other arms can make up for it until the arm regrows, which it does after a while. They are all connected to the center of the starfish which should not be damaged.
When the electron wavefunction is bound in a stable state in an atom it stretches into a 'orbital' form. There was a mistake. When attached in a stable atomic state, an electron often acts like a three-dimensional oscillating wave, i.e. the orbital vibrates. It's sort of like a vibrating chord.
Answer:
I think it is C but I'm not 100% sure
