Inner membrane of the chloroplasts
Explanation:
The present day eukayrotes are all considered to be derived from its original ancestor – the cyanobacteria.
Earlier, photosynthesis by the first photoautotrophs took place utilizing hydrogen sulphide as the electron donor. However, it was later when the cyanobacteria, which were originally residing in the mitochondria of an eukaryotic cell under an endosymbiotic relationship, developed into true chloroplasts, the use of water as electron donor to perform photosynthesis began.
The cyanobacteria were aerobic in nature and required oxygen to survive. They evolved the chloroplasts covered with an external protective membrane and an internal membrane. It is the internal membrane which contains all the necessary organelles or components necessary for photosynthesis like thyllakoids, stroma etc which helped them to utilize water as an electron donor during photosynthesis like all the eukaryotes.
The answer is; warming of ocean water in the east of the Pacific Ocean close to the western coasts of South America.
The warming of the oceanic waters causes a current that pushes the warm waters eastwards of the Pacific Ocean at the equator. This counters and overpowers the prevailing trade winds that blow westwards. The currents bring in storms on the West coast of South America as the currents exchange heat with the atmosphere .
They are all made of eukaryotic cells and have a nuclei
