Answer:
D: Carbon
Explanation:
Carbon is the sixth element with a total of 6 electrons in the periodic table. Hence the atomic number Z = 6. The ground state electron configuration of carbon is 1s2 2s2 2p2. An excited state electron configuration of carbon is 1s2 2s1 2p3.
The shape of a protein molecule resembles BEADS ON A STRING.
Proteins are macro molecules that are formed from amino acids. There are different types of amino acids, thus, different amino acids combine together to form different types of protein. This means that, proteins are formed from sequences of amino acids; they are long chains of different amino acids, that is why, they are likened to beads on string.
The structures of proteins are in three dimensions, they are primary, secondary and tertiary structures. The primary structure refers to the sequence of the amino acids in a protein. The amino acids in the primary structure are linked together by peptide bonds.
Answer:
Its properties remain unchanged as it is undergoing physical changes.
Explanation:
Hello.
In this case, since aluminum foil is made up of aluminum leaves having a 0.2-mm thick it is widely known that is deformed when wrinkled due to its tiny average thick. Moreover, when cut half over and over again smaller pieces are obtained every time it is done. Nevertheless, even when its shape and size can be modified via physical actions, its properties remain unchanged because cutting is a physical change which is not affecting its chemical composition.
Best regards.
