Answer:
1. Protein - build lean muscle and strengthen tendons
2. Lipids - insulation and long-term energy
3. Carbohydrates - provides quick, easily digested energy
4. Nucleic Acids - repair and replicate DNA and RNA
Explanation:
a. Think of protein as what helps your muscles grow and strengthen
b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)
c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.
d. nucleic acids - think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.

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.
Answer:
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. In Darwinian terms the phrase is best understood as "Survival of the form that will leave the most copies of itself in successive generations."
