Please correct answer and don't use hand rating Choose the true statements about amyloid fibrils.Proteins that convert to an amyloid structure form soluble fibrils.☐ Amyloid fibrils have a high amount of α-helical structure.☐ Nucleation of amyloid structure may be triggered when two ẞ-sheet regions from two partially folded proteinsassociate.☐ Proteins that form amyloid fibrils are normally soluble.Some amyloid fibrils are formed from proteolytic fragments that self-assemble into extended ẞ-sheet structures.

Which statements accurately describe soap? Select one or more: Soaps are a mixture of fatty acid salts and glycerol. Soaps react with ions in hard water to create a precipitate. Soaps should be weakly alkaline in solution. aps work in solutions of any pH. Soaps are both hydrophobic and hydrophilic.
Which of the following accurately describes why specific material uses a protein to cross the membrane? Material can only cross the membrane via a protein. The membrane will allow any substance to cross it if the concentration of solute is high enough on one side of the membrane. The hydrophilic core of a membrane will only allow hydrophilic (i.e., polar) substances to cross without a membra protein. The membrane will allow any substance to cross it as long as it moves from a high concentration to a low concentration. The hydrophobic core of a membrane will only allow hydrophobic (i.e., non-polar) substances to cross without a membrane protein.
Which statement about the lipid bilayers around cells is TRUE? They are single layers of molecules that allow only water molecules to pass through freely. They are permeable membranes that allow ions and water molecules to freely pass through. They are semipermeable membranes made of a double layer of molecules. They are double layers of molecules that do not allow any substance to pass through.
