Which of the following conclusions might a scientist make when fossils of two different species of very similar organisms are found in different layers of rock? Question 2 options:

A. Both organisms had similar behaviors.

B. One organism was prey for the other organism.

C. One organism was ancestor of the other organism.

D. Both organisms lived around the same time.

c) should be the answer.

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.
