Answer:
The correct answer is A. control the movement of substances in and out of the cell.
Explanation:
All cell membranes are made up of lipids and proteins. Lipids are organized in two closely adjoining sheets that form a lipid bilayer. This bilayer provides the basic structure of the membrane and acts as a permeability barrier (impermeable) for most water-soluble molecules. Cells live and grow by exchanging molecules with the surrounding environment and the plasma membrane acts as a barrier that controls the transit of molecules into and out of the cell. As the interior of the membrane (the lipid bilayer) is hydrophobic, the membrane tends to block the passage of almost all water-soluble molecules (which dissolve in water). Protein molecules, which are normally “dissolved” in the lipid bilayer, act as mediators or facilitators of almost all membrane functions, either by transporting specific molecules through it or by catalyzing membrane-associated reactions, such as synthesis of ATP.
Once car production was becoming more efficient and cars became more affordable to American families the growth of suburban areas around urban centers increased.
There are good arguments on both sides as to when and how fast to reopen the economy. In my view, the answer will vary state by state and industry by industry. There’s also an enormous amount of uncertainty as to exactly how to determine the optimal policy. In that environment, there’s a great advantage to having these decisions be made at as local a level as possible. Thus, while I suspect that Sweden’s current policy is not optimal, that Nordic country is doing a great service to Europe by providing evidence on the consequences of an alternative policy path.
Giving too much power to any one person is dangerous, especially when that person might be influenced by political considerations that go beyond the best interest of the country as a whole:
That’s not to say Trump’s views are necessary wrong; rather that the procedure he uses to reach decisions is not reliable. Thus I’d still favor local control even if in one particular case you could convince me that the views of the person who happened to be president at the time were superior to the views of the average mayor or governor. In the long run, competition between states will produce better governance than central planning.
