Answer:
C. 50%
Explanation:
One of the grapefruit plant is fully white, while the other is heterozygous red:
fully white: bb (If it was BB, then the heterozygous would be white, as it would take on the dominant trait).
heterozygous red: Bb (Red is the dominant trait, denoted by <em>B</em>).
Create the Punnett square:
![\left[\begin{array}{ccc}&b&b\\B&Bb&Bb\\b&bb&bb\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26b%26b%5C%5CB%26Bb%26Bb%5C%5Cb%26bb%26bb%5Cend%7Barray%7D%5Cright%5D)
As such, the fully white (bb) takes up 50% of the Punnett squre offsprings, which makes your answer C.50%

Answer:
The given blank can be filled with histones.
Explanation:
The family of basic proteins, which associate with the DNA in the nucleus and assist in condensing it into chromatin are known as histones. The nuclear DNA does not come in the form of free linear strands, it is heavily condensed and enveloped around the histones so that to get fit within the nucleus and take part in the generation of chromosomes.
These are the basic proteins, and because of their positive charge, they get associated with the DNA. Under the microscope, chromatin appears like beads on a string. The beads are known as nucleosomes. Each nucleosome comprises DNA wrapped around the 8 histone proteins, which works like a spool and is known as a histone octamer.
