Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment. Ice cores drilled through glaciers and ice sheets like in Antarctica tell us about such things as the concentration of greenhouse gases like carbon dioxide (as bubbles in the ice layers) and also about climatic conditions in glacial and interglacial periods.
Mitosis: producing body cells
Meiosis: producing sex cells
Prophase and anaphase both occur, but meiosis produces 4 cells and mitosis produces 2.
The answer to the given question above would be the second option. Based on the given scenario above, the reason why the new rodent with the nearby rodents and gets viable but infertile offspring is that the <span>new rodents probably derive from fairly recent ancestors that experienced dispersive allopatric speciation. Hope this helps.</span>
<h3>
NEUTRONS AND PROTONS</h3>
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.
