Hey there!
It is mostly like "B". A new area of science promotes experimentation from a different point of view because everything else is explains why the development of the new area of science which could lead to change in a particular theory but they aren't quite the "best" one
SO, that is why
is mostly likely your result
Good luck on your assignment and enjoy your day!

The answer, I believe, is all of the above.
Hope this helps!!
There are multiple energy source in the ocean. The one thats probably the most common one are Dams. Although Dams can cause some serious flooding. Another one is Tidal energy. Tidal energy is something that turns the energy of tides into energy through Kinetic motion.<span />

Answer:
The macromolecules that forms pumps and channels in the cell membrane, allowing the entry and exit of molecules to the cell are protein.
Explanation:
Membrane integral proteins are a type of macromolecule attached to the structure of the membrane and have ends in contact with the cytoplasm and the extracellular medium.
These <u>protein molecules can act as channels and transporters or pumps</u>, to facilitate the passage of substances through the membrane. An example of transmembrane channels are ion channels, while a protein transporter is the sodium potassium ATP-ase pump.
Membrane proteins can also act as surface receptors and enzymes linked to the cell membrane.
The other options are not correct because
:
- <em><u>Carbohydrates</u></em><em> can be found on the membrane bound to other molecules, such as glycoproteins and glycolipids, but they do not act as pumps or channels.
</em>
- <em><u>Lipids</u></em><em> have the function of being the main component of the cell membranes.
</em>
- <em><u>Nucleic acids</u></em><em> are found in the nucleus, and are not part of the cell membrane.</em>
