Answer:
Structurally, proteins are different from carbohydrates because all proteins contain nitrogen (option C).
Explanation:
The basis of the chemical composition of proteins is carbon, hydrogen, oxygen and nitrogen, so all proteins have nitrogen in their structure. Some proteins also possess phosphorus and sulfur atoms, among others.
Proteins are biomolecules formed by the union of multiple amino acids through carboxyl-amino bonds, called petidic bonds. Their content of nitrogen and other atoms in their structure is what makes them different from carbohydrates.
The other options are not possible because:
- <em>Only some proteins contain </em><u><em>iron</em></u><em> in their composition.</em>
- <u><em>Potassium and helium</em></u><em> are not part of the protein structure.

The sky is blue due to Rayleigh scattering.
Particles in our atmosphere split the white light that the sun emits to the shortest wave length
(Blue)
Skies becomes red during the sunset since an angle forces the light to travel through more dust particles making it a longer wavelength
(Red)
Water in the clouds are not small enough to split light into a specific colour so it remains the same
(White)
I would appreciate a brainliest.
Answer:
Rudolf Virchow's most widely known scientific contribution is the cell theory, which built on the work of Theodor Schwann. He was one of the first to accept the work of Robert Remak, who showed the origins of cells was the division of pre-existing cells.
