Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate
The answer is B- the forces air puts on the area around it.
By left I guess that you mean the western side of the Pacific Basin. There is no longer a spreading ridge on the western side of the Pacific Basin--so the floor is no longer spreading. The seafloor and the paleomagnetic stripes on the seafloor of the Western Pacific were actually created many millions of years ago. In fact, the western side of the Pacific Basin is being subducted--so, the western ocean floor is actually disappearing beneath Japan, New Zealand, etc.
<span>In the southeastern part of the Pacific, there is still a spreading ridge, the East Pacific Rise, off of Central and South America. And there are little remnants of spreading ridges just off the the Northwest coast of North America </span>
<span>The Atlantic Basin, on the other hand, which has a spreading ridge right down its middle, and has only insignificant subduction along its margin (beneath Caribbean plate), is still getting wider. </span>
