The atmosphere, climate, etc, the answer could be a great number of things, it isn't just one specific answer.
Perhaps there is a set of vocab that you can choose from? If so, then please list it.
An integral membrane protein is a kind of membrane protein, which is perpetually combined with the biological membrane. All transmembrane proteins are integral membrane proteins, but not all integral membrane protein are transmembrane proteins.
These proteins are anchored in the lipid bilayers and only non-polar, hydrophobic amino acid residues would be found in the part of the protein, which crosses the membrane. In the interior of the bilayer, these residues would be hidden from the water solvent and associate with the non-polar lipid tails.
Answer:
Energy can pass from one trophic level to the next when organic molecules from an organism's body are eaten by another organism. ... On average, only about 10% of the energy stored as biomass in one trophic level—e.g., primary producers—gets stored as biomass in the next trophic level—e.g., primary consumers
B) Proteins
Lipids and Carbohydrates only contain carbon, hydrogen, and oxygen.
Unsaturated fats are a type of monomer for lipids, meaning they as well are only made up of carbon, hydrogen, and oxygen.
