The graph below is derived from coastal tide and satellite data. It shows how much sea level changed from about 1870 to 2018. Items with pluses (+) are factors that cause global mean sea level to increase, while minuses (-) are variables that cause sea levels to decrease. These items are displayed at the time they were affecting sea level. According to the graph, melting ice sheets and glaciers combined with thermal expansion as factors increasing sea level rise. What additional variable may have caused the rate of sea level rise between 2000 and 2020?

- More global dams
- Refreezing Arctic
- Ocean circulation
- Cooler Antarctic

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.

hope this   and an i get brainlsiest
