Complete the following concept map to review some of the concepts of gas exchange.
To complete: The given map to review some of the concepts of gas exchange.
Introduction:
The respiratory system is a biological system that ensures the transport of air by the process of inhalation and exhalation, that is, in and out the body with the help of the lungs.
Answer to Problem 1CC
Fig.1 shows the completed map to review some of the concepts of gas exchange.
Pictorial representation: Some of the concepts related to gas exchange are presented in the concept map given in Fig.1.
Fig.1: Concepts of gas exchange.
Explanation of Solution
a.
Correct answer: Respiratory surface.
For gas exchange to occur, the respiratory surface should be thin and moist. Hence, the correct answer is the respiratory surface.
b.
Correct answer: Circulatory system.
Gas exchange relies on the circulatory system as the exchanged oxygen and carbon dioxide travel in the blood to the heart and different body cells. Hence, the correct answer is the circulatory system.
c.
Correct answer: Lungs
It is the main organ for the exchange of gases consisting of air sacs that carry out gaseous exchange and the blood carries the exchanged gas to the tissue cells. Hence, the correct answer is the lungs.
d.
Correct answer: Hemoglobin.
Hemoglobin is a blood pigment present inside the red blood cell, which helps in the transport of oxygen and carbon dioxide by binding with it and also maintains the pH of the blood. Hence, the correct answer is hemoglobin.
e.
Correct answer: Cellular respiration.
In cellular respiration, oxygen is used to convert glucose into carbon dioxide, water, and energy in the form of ATP. Hence, the correct answer is cellular respiration.
f.
Correct answer: Negative pressure breathing.
This type of breathing is regulated by the “breathing control center of the brain”. In negative pressure breathing, the air pressure inside the lungs drops during the contraction of the diaphragm, and the lower portion of the chest cavity rises; this allows the movement of air from outside to inside. Hence, the correct answer is negative pressure breathing.
g.
Correct answer: Oxygen.
Hemoglobin pigment in the blood binds with the oxygen present in the lungs, and this oxygen is utilized to form energy. Hence, the correct answer is oxygen.

- Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females.

What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected.
