Some scientists claim that the gene that controls the production of
hemoglobin, a protein responsible for the binding of oxygen to red blood
cells in humans, is found in a specific location on a specific chromosome.
Which of the following observations would provide the best evidence for
this claim? *

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
