The norm is to place the independent variable on the “x”or horizontal axis and the dependent variable on the “y” or vertical axis.
<span>One characteristic of most of the tropical open oceans that is directly responsible for the low chlorophyll levels in these waters is </span>Low nutrient concentrations.
<span>Part
a the adaptation that made possible the colonization of dry land environments
by seed plants is most likely the result of the evolution of pollen.</span>
The main advantage of seed plants
(Gymnosperms and Angiosperms) is the evolution of the seed which, unlike
spore-producing plants, was not limited to wet environments. Pollen grains are
male gametophytes (sperm) which are protected from desiccation and can reach
the female organs without dependence on water. The sperm is transferred from
the pollen through the pollen tube: an extension of a cell within the pollen
grain. The process is called pollination.
