On any given blank there are a number of genes but not all the genes will be coding for patients

The right answer is B. Chromosome

In its most scientifically rigorous definition, a chromosome is a fully condensed structure of chromatin.

In optical microscopy, condensed regions formed of heterochromatin and decondensed regions of euchromatin are distinguished on the chromosomes. The genes expressed are located mainly at the level of euchromatin.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
