The drawing shows two long rod-shaped structures with horizontal light and dark bands. how do these structures function in the inheritance of traits? the two long structures are genes made up of dna and the bands are chromosomes that can make individual proteins. b the two long structures are genes that contain dark rna bands that carry information for manufacturing proteins to the cytoplasm of the cell. c the two long structures are chromosomes that are made up of dna, and the bands include genes which carry information concerning how to make proteins. d the two long structures are made up of rna, and the light bands are made up of dna which carries information to the cytoplasm of the cell from the nucleus to make proteins.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.
