Answer:
C) Rr Only
Explanation:
The genotype of true breeding red parent plant is "RR" and that of the true breeding white parent plant is "rr". The red parent plant with "RR" genotype will form all the gametes with "R" allele while the white parent plant with "rr" genotype will form all the gametes with "r" allele. The random fusion of these gametes will form all the progeny with "Rr" genotype.
Since "R" is incompletely dominant over "r", the progeny with "Rr" genotype would have pink flowers.
Answer:
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host.
So life itself is an emergent, complex state, but it is made from the same fundamental, physical building blocks that constitute a virus. Approached from this perspective, viruses, though not fully alive, may be thought of as being more than inert matter: they verge on life.

Answer:
Animal cells have a cleavage furrow which will pinch the cytoplasm into two nearly equal parts. While plant cells have a cell plate that forms halfway between the divided nuclei.
