Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances. Consequently, genetic variation is often considered an advantage, as it is a form of preparation for the unexpected.
The debate<span> you refer to is about the ethics of embryonic </span>stem cell research<span>. And, of course, since ethics is involved many would tend to oppose further research on this area because to them it violates and does not respect life. Hope this helps. Have a nice day.</span>
Explanation:

Yea that is true but more stuff is maybe made more
Answer:
Dendrochronologists have shown that tree-ring data produce a remarkably accurate history of droughts and other climate changes.
Explanation:
The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age. In dry environments, such as the Middle East or U.S. Southwest, tree rings typically record wet or dry years, and in cooler areas (high latitudes or high elevation), the ring widths are often a proxy for temperature.
