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>
Answer A. If the tectonic plates continually move then they change earth’s crust constantly.
- Radiation
- Convection
- Conduction
According to the research, the correct option is B. A <u>theory</u> is the element of the scientific process that would include the greatest amount of information about living things.
<h3>What is a theory?</h3>
It is a set of ideas or proven hypotheses that explain some phenomenon studied or a scientific description based on a set of observations or experiments.
In this sense, it is a logical system that is established from observations, axioms and postulates, and is formed by the set of concepts, propositions and definitions that are related to each other with the aim of explaining the given phenomenon.
Therefore, we can conclude that according to the research, the correct option is B. A <u>theory</u> is the element of the scientific process that would include the greatest amount of information about living things.
