Some data suggest that the average global
temperature will increase by 1°c–2°c by the
year 2050. if this occurs, a major concern for
humans would most likely be that
(1) sea levels might rise enough to flood some
coastal areas
(2) long-term stability of the climate will benefit
ecosystems
(3) the availability of salt water for agricultural
use will increase
(4) the threat of extinction of land organisms will
decrease

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
