Answer:
The correct answer would be - zero miles, 600 miles.
Explanation:
She started from the same point and after the trip, she ended it on the same point in Philadelphia therefore the displacement is expected to be zero.
The distance she traveled would be 2 into 300 miles as she traveled to her sister and traveled back from there so
Distance = 2*300
= 600 miles.
Thus, the correct answer would be - 0 and 600 miles.
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>
the highest humidity would be texas i know that for sure but on here i'd say it is arizona
The difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.
