Answer:
The plasma membrane is selectively permeable; hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot. Integral membrane proteins enable ions and large polar molecules to pass through the membrane by passive or active transport.
Explanation:
Thank you for posting your question here at brainly. The reason why packets of protein collected in a vacuole might merge with lysosomes is <span>because the vacuole cannot contain the proteins being collected so it overpowers and leak onto to merge with lysosomes.</span>
The results will most likely be valid because the scientists kept getting the same results after REPEATED experiments. If they just conducted one experiment then they would not have been sure if what happened was a fluke or if another thing would happen after another experiment.<span />
