Question
Chapter 17, Problem 1SQ
Summary Introduction
Concept introduction: The most basic and ancient branches of the tree of life defines three domains. All the life forms in the environment belong to one of this domain system. The domains are again divided into kingdoms.
Expert Solution & Answer
Answer to Problem 1SQ
Correct answer: Archaea, Bacteria, and Eukarya are the groupings that list only domains. Therefore, option c. is correct.
Explanation of Solution
Reasons for the correct statement:
The three-domain system organizes all the lifeforms on the Earth into three large categories or domains. The three domain systems are Bacteria, Archaea, and Eukarya.
Option c. is given as “Bacteria, Archaea, and Eukarya”. As Bacteria, Archaea, and Eukaryaare the three domain systems, option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “Eukarya, Bacteria, and Animalia”. Animalia is not one among the three domain systems. Therefore, option a. is incorrect.
Option b. is given as “Plantae, Protists, and Archaea”. Plantae and Protists are not included in the three domain systems. Therefore, option b. is incorrect.
Option d. is given as “Bacteria, Archaea, and
Hence, options a., b., and d. are incorrect.
Conclusion
The three domain systems include Bacteria, Archaea, and Eukarya.

6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in
relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in
diving humans.
• How might the location and slope of the O2 line differ for diving marine mammals such as
whales and dolphins?
•
How might the location and slope of the CO2 line differ for diving marine mammals such as
whales and dolphins?
•
•
Draw in predicted lines for O2 and CO2, based on your reasoning above.
How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line
differ for diving marine mammals?
What physiological mechanisms account for each of these differences, resulting in the ability
of marine mammals to stay submerged for long periods of time?
How much ATP will be produced during the following metabolic scenario:
Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA.
Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
