The monocot is the plant that has only one cotyledon in the embryo, whereas dicot is the plant that has two cotyledons in the embryo. ... The other big difference between the monocot roots and dicot roots is the presence of some xylem and phloem. In monocot roots, the xylem and phloem are numerous in numbers.
Answer:
They know that layering, or bedding, is the most obvious feature of sedimentary rocks. This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air. That is kinda easy :D
Explanation:
Liquid water evaporates from lakes when heated by the sun.
Answer:
The two main reasons are nonpolar core of the bilayer and the active transport.
Explanation:
The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.
If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.
One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>
