What are three ways that biochemists study biological organisms?
Biochemists study 1) the relationship between structure and function of biomolecules, 2) chemical reactions of organisms (metabolism), and 3) communication within and among organisms.
What is the definition of biochemistry?
Often referred to as the chemistry of life, biochemistry asks how the remarkable properties of organisms relate to their molecules.

What is the bond angle associated with trigonal pyramidal
107.5 degrees
Are transition metals commonly found in biological organisms?
Yes. They are trace elements in organisms. See Figure 1.3 for examples.
True or false: Water can make up 85% (by mass) of a living organism. True. Some plants are made up of 90% water by mass.
Question 9 pts
True or false: Large elements tend to make the strongest covalent bonds. Question 11 ptsQuestion 10 pts

Bulk elements (three of these): H, C, N, O, Na, P, S, Cl, K, and Ca Trace elements: Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Mo, I, and W.
The following statement is incorrect. Rewrite the statement to be correct.
Statement: Organic chemistry is the study of metal compounds, while inorganic chemistry is the study of carbon compounds.
Organic chemistry is the study of carbon-based compounds,
while inorganic chemistry is the study of all other compounds,
including metals, minerals, and other non-organic compounds.
Is H2O an organic molecule? How about CO2? C100H202?
Water is not organic; it does not contain carbon. Both CO 2 and C100H202
are organic compounds.
The next row of Table 1 would be the 6-carbon alkane, hexane. Write out its chemical formula and condensed formula.
