I believe this is the best one:
B. The volume of water will increase if cooled from 3°C to 2°C.
I don't think D) because water expands from 4°C to 0°C
"When liquid water is cooled, it contracts like one would expect until a temp of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point."
it has an electrons in a fixed path together on energy levels.
Answer:
Primary structure is the correct answer.
Explanation:
- The primary structure is the simple level of protein structure.
- Primary structure is a basic amino acids sequences in a protein.
- In the primary structure, amino acids are attached together by a covalent bond.
- Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains
- Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.
Explanation:
Composed of molecules formed by atoms of two or more different elements.
Most atoms do not. For those atoms that do not have a full valence shell (which usually would contain eight electrons, except for hydrogen and helium, where it would contain two), something has to change. So nature's tendency toward a full valence shell will lead to one of two things: The gain or loss of electrons.
