Answer:
The correct answer is "cleaves the Holliday intermediate by replacing one RuvA with RuvC".
Explanation:
RuvABC is a three proteins complex that is critical for DNA repair in bacteria. RuvAB is a helicase that is comprised of two of the tetramers of the complex that besides mediating branch migration, cleaves the Holliday intermediate by replacing one RuvA with RuvC. RuvAB perform its molecular activity by by localized denaturation and reannealing.

Before we answer your question, let's put your data into a Punnet square. The problem says that two heterozygous individuals will mate, so that means their phenotype is Pp.
P p
P PP Pp
p Pp pp
When you read a Punnet square to look for gentoypic ration, it refers to the Genotype, or let's just say the code and just count how many genotypes combinations you see out of the total, which in this case is 4.
PP = 1 out of 4 = 25%
Pp = 2 out of 4 = 50%
pp = 1 out of 4 = 50%
When we look at phenotype, we look for the trait that is expressed. If that is the case, you should remember that the dominant trait is ALWAYS expressed over the recessive. So if the genotype is Pp, the trait of the P is going to be expressed.
Polka-dot (P) = PP and Pp = 3 out of 4 = 75%
Solid (p) pp = 1 out of 4 = 25%
So looking at the result, the answer would then be B. 75% chance of a polka-dot tail and 25% chance of a solid tail (25%PP, 50%Pp and 25%pp).
Answer: Option D.
Crystalline and rigid.
Explanation:
When liquid freezes to ice, it becomes solid and this is crystalline and rigid because a solids for crystals which means solid atoms, molecules or ions are orderly arranged in structures which form of crystal lattice in all sides. The structure of solid becomes rigid , it does not take the container shape like liquid and it does not expand also like liquid. it volumes reduces.
