Answer:
Phytoplanktons are microscopic creatures that are primary producers of oceans. Phytoplanktons take carbon dioxide from atmosphere to make their food and then they are eaten by some other animals of oceans.
Phytoplanktons are present in huge numbers in oceans and have a great contribution to the carbon cycle because it is responsible for the transfer of carbon dioxide from the atmosphere to the oceans.
Most of the carbon is released through combustion by animals that eat phytoplanktons but some accumulate in the ocean floor because some dead phytoplanktons settles down in the ocean.
The retina and optic nerve are part of the central nervous system, as they are derived from the neural tube. We know that oligodendroglia provide myelin for the central nervous system and Schwann cells provide myelin for the peripheral nervous system. Therefore, oliogodendroglial cells must provide the myelin for the optic nerve.
The blue whale! It’s actually not only the biggest animal in water but also the biggest animal in the world! :)
A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor. In other words, it’s when very different animals have bones that appear very similar in form or function and seem to be related<span>

According to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.
<h3>What is the
hydrological cycle?</h3>
It is the water cycle that allows water to pass from the earth's surface to the atmosphere so that it can then return to its liquid and solid phases. .
In this process, therefore, sublimation, evaporation and transpiration play an essential role where 70% of the earth's surface is covered by liquid water, of which 97% is salt water that forms the oceans.
Therefore, we can conclude that according to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.
