Which statement best explains why correct protein folding is critical in the transmembrane protein shown above?
amid [387]

The statement 'interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane' explains why protein folding is critical. This process is fundamental for the function of transmembrane proteins.

Protein folding refers to the process by which a polypeptide (i.e., a protein) adopts its final tridimensional 3D shape (conformation).

In a protein, some amino acids contain hydrophilic R groups, whereas other amino acids contain hydrophobic R groups.

During protein folding, hydrophobic amino acids are arranged so they can interact with the long chains of the fatty acids in the internal region of the lipid bilayer, whereas hydrophilic amino acids are arranged so they interact with water on the surface of the cell membrane.

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hea
Ronch [10]

Answer:

Diffraction

Explanation:

Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.

Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

hope this helps :)

Why does the nuclear membrane need to dissolve at the start of mitosis?
Molodets [167]

Answer:

The nuclear envelope does not disappear in metaphase of mitosis, because it already did in prophase. ... The nuclear envelope needs to be broken apart so that the chromosomes can be found, aligned in the middle of the cell, and then pulled apart.
