Answer:
As taxon is part of the taxonomic category it is constructed by individual biological objects. -Species contains a group of individuals with same morphological characters and they can breed among themselves whereas taxon is a group of one or more population of an organism in taxonomical form.
Explanation:
If the pH/temperature fluctuates, the enzyme conditions would no longer be favorable, meaning the enzyme would no longer be able to perform its assigned function. If the conditions become too unfavorable, the enzyme would change shape (denature).
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.
