Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
Answer:
In an experiment, the researcher needs to have a control group with an experimental group where both groups are identical in every way except that the controlled group does not gets the experimental treatment.
Sometimes, it is not possible to do a test or the experiment utilizing a controlled trial (due to ethical reasons or no practical method available). All things considered, a researcher may test a theory by making predictions about outcomes or patterns that ought to be found in nature if the hypothesis is right.
