The respiratory zone is the site of 02 and CO2 exchange with the blood;
site of gas exchange.
The equator receives about the same amount of sunlight all year long.
Ocean acidification reduces the amount of carbonate, a key building block in seawater. ... Some algae and seagrass may benefit from higher CO2 concentrations in the ocean, as they may increase their photosynthetic and growth rates.
The specific term to characterized the downward
growth of roots in response to earth’s gravity pull is called positive geotropism.
The word geotropism was derived from two words, “geo” which means ground and “tropism”
which describes a plant movement elicited by a gravitational stimulus.
In addition, the root cap makes the roots turn
downward as they grow for they have specialized cells with sensors called
statoliths that settle to the lowermost part of the root cap in response to the
pull of gravity and help the cell multiply more rapidly in a downward direction.
