Neanderthals is the closest relative to modern human. According to the study of evolution of man, neanderthals are the one with the closes facial structure and body structures to human.
Their higher classification is already considered as human.
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.
</em>
Answer:
the branch of science concerned with the chemical and physicochemical processes and substances that occur within living organisms.
Explanation:
Answer:
4
Explanation:
If we have the expression, 3/3/4.
Then this is the same as 3 × 4/3
Which is the same as 12/3
Which is the same as 4
Hence the value of the expression 3/3/4 is 4
Answer:
Oxidative Phosphorylation
The mitochondria is one of the double membrane organelles with specialized energy-producing functions, that is, reduced nucleotides to finally form the cellular energy currency that is ATP. The 5'-triphosphate adenosine molecule (ATP) is synthesized in the inner mitochondrial membrane as a subsequent step to the electron transport chain through oxidative phosphorylation. This process takes advantage of the flow of protons or proton motive force, detected by an electrochemical differential of H +, to produce ATP through the complex V of the mitochondrial inner membrane. Together with photosynthesis, it is one of the most important energy transduction processes in the biosphere.
Oxidative phosphorylation: Synthesis of ATP
The mitochondria, in its inner membrane, is the place of the electron transport chain and oxidative phosphorylation, | Mitochondrial electronic transport and oxidative phosphorylation are the mechanisms that aerobic organisms use to synthesize ATP from reduced organic molecules.
