Answer/Explanation:
If a protein has a quaternary structure it is formed when many subunits get together.
- true. The quaternary structure of a protein is the final stage in its assembly, when structures from multiple polypeptides come together, forming a multi-subunit protein (e.g. a dimer if 2, a trimer if 3 and so on)
Monomers form the secondary structure of proteins.
- false, they form the tertiary structure
The charges on the functions groups of the amino acids creates the beta pleated sheets and alpha helix structures that are the secondary level of structure in proteins.
- false, it is mostly the peptide backbone that causes the alpha helices and beta sheets to form
The order of the amino acids is the primary structure of proteins. - true. The amino acid sequence linked together by peptide bonds is the polypeptide sequence, which then forms increasingly complex structures when folded.
The tertiary structure of proteins is formed when the B sheets and alpha helices organize themselves into a more complex shape. - true. These complex structures can further interact with one another to form increasingly organized domains. The amino acid side chains possess different properties that form different bonds with one another.
The primary structure of proteins is formed from the amino groups on the proteins. - false, the primary structure is formed by the sequence of amino acids in the chain, determined by the mRNA sequence from which the protein is synthesised.

The answer is <span>B. meiosis.
All cells in an organism are diploid (2n). Only reproductive cells are haploid cells (n). Mitosis is a division of a cell into two daughter cells identical to the mother cell. Meiosis is a cell division during which the number of chromosomes is reduced by half (from 2n to n). So, reproductive cells (n) are created by meiosis.
Cytokinesis is the phase during mitosis and meiosis.</span>
-Viruses can't reproduce by themselves. They require a host animal to do so.
-Viruses are not made of cells
-They can't keep themselves in a stable state (regulate temperature)
-They don't grow
-They can't make their own energy
Hope this helps :)
