Answer:
Dark colour occurs.
Explanation:
The amino acid changes in the MC1R protein may change the structure and function of the protein because the amino acids are the building blocks of proteins. This change in amino acid leads to increased production of eumelanin, which results in the dark color of the protein. So we can say that change in the amino acids leads to the change in the structure and function of MC1R protein.
Answer:
The correct answer is: catalysts lower the activation energy of the reaction.
Explanation:
Catalysts are substances that in our bodies are commonly represented by enzymes (specialized proteins) and that are used in chemical reactions to speed them up.
In order to achieve this, catalysts lower the activation energy of chemical reactions, which is a value of energy that must be obtained for the reaction to actually happen.
Catalysts are constantly used in our bodies and are responsible for the proper functioning of every organ. These catalysts can be used over and over again because they are not consumed in the reaction.
The answer is A i believe
These organelles group together to eventually form cells, or the basic units of all living things.
Organelles are specialized structures in the cytoplasm of cells which provide essential cell functions and are composed of different molecules (macromolecules). Cells as the smallest basic units of life are then grouped in tissues (similar cells which provide a specific function), layers of different tissues work together to provide specific function and form organ, organ group in organ systems which then compose the whole organism.
i would say that the student is incorrect. temperature can flucuate but that doesnt indicate error
