Question

an example of a biomarker is
a cholesterol.
b any dna sequence.
c sodium chloride.
d hydrogen.

question 46
conformation is
a the three - dimensional shape of a molecule, such as a protein.
b the energy held in the bonds of an organic molecule, such as a protein.
c the ability of dna to copy itself.
d the amino acid sequence (primary structure) of a protein.

Explanation:

First Question (Biomarker Example)

A biomarker is a measurable indicator of a biological state. Cholesterol levels are used as biomarkers for cardiovascular health. Option B is incorrect as not all DNA sequences are biomarkers. Sodium chloride (C) and hydrogen (D) are not typical biomarkers.

Conformation refers to the three - dimensional shape of a molecule. Option B is about bond energy, C is DNA replication, and D is the primary structure of a protein (amino acid sequence), not conformation.

Answer:

A. cholesterol.
