Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.
Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.
Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones
Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.
Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.

The main difference between organ and organelle is that organ is a large part of an organism, composed of tissues which perform similar functions whereas organelle is a specialized structure found inside cells, which carries out a specific life process. ... Organelles occur in all eukaryotes. They are microscopic
Answer:
It lacks a nuclear membrane and resides inside the nucleus.
Explanation:
The nucleus is considered as controlling centre of the cell. The parts of the nucleus includes nucleolus, nuclear pore, chromatin, and nuclear envelope. Nucleolus is the part of the nucleus which is present inside the cell and lacks a nuclear membrane and its function is producing and assembling of ribosomes.
The reason for not considering other statement as true are as follows:
1. Nucleolus is found only in Eukaryotas.
2. Nucleus is the control centre of the cell.
3. It lacks a nuclear membrane and resides inside the nucleus.
