Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically. The meridians are equally spaced parallel vertical lines, and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as their distance from the Equator increases. This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps, however, because the scale is distorted; areas farther away from the Equator appear disproportionately large. On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula.
Regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.
- Stem cells are specific cells capable of generating new specialized types of cells, thereby allowing the regeneration of damaged tissues.
- For example, hematopoietic stem cells can be used to generate new red blood cells whose function is to transport oxygen in the bloodstream.
- Regenerative cells can be used in tissue engineering in order to restore the function and structure of damaged organs.
In conclusion, regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

Answer:
Instead of a brain, echinoderms have a ring of nerves located around their mouth area that governs their nervous responses. This ring coordinates their motion, their eating, basically anything that requires nerve control.

Answer:
As one goes up the other does as well for the first 2 but they aren't proportional (it is not simple cause and effect as there is a lot of factors)
The last question is to decrease their emissions as rising temperature is being effected by rising CO2 levels and rising temperature can cause a feedback loop causing more rising temperature
