Expert Solution & Answer

Summary Introduction

Introduction:

The respiratory system consists of a network of organs that work concertedly to bring about the gaseous exchange. It primarily involves two parallel processes namely inspiration (intake of gases) and expiration (exhalation of gases). These two processes help to maintain a proper gaseous homeostasis that is essential for the survival of an organism.

Answer to Problem 1MC

Correct answer:

Expiration begins at the gaseous exchange site of alveolus followed through bronchiole to bronchus, reaching to trachea then larynx, and is finally expired through nasal cavity through pharynx.

Explanation of Solution

Explanation for the correct answer:

Option (d) states the expiration route as alveolus, bronchiole, bronchus, trachea, larynx, pharynx, and nasal cavity. Expiration removes gases from the system and it follows the pathway governed by respiratory anatomy. The organ sequence in the respiratory anatomy in expiration is alveolus, bronchiole, bronchus, trachea, larynx, pharynx, and nasal cavity. Hence option (d) is correct.

Explanation for incorrect answers:

Option (a) mentions that the expiration occurs through larynx followed by trachea, which is incorrect because larynx lies downstream of trachea in expiration anatomy. So, it is an incorrect option.

Option (b) explains the expiration route through trachea followed by bronchus. This statement contradicts with the actual anatomical position of trachea, which is downstream of bronchus. So, it is an incorrect option.

Option (c) mentions that bronchus lie upstream of bronchioles in respiratory anatomy. The precise anatomical position of bronchus is downstream of bronchioles. So, it is also an incorrect option.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

Expiration is involved in the removal of excessive gaseous materials from the body, which ensures that a balance between gaseous contents is maintained so, as to suit the physiology of an organism. The path of expiration is strictly under the control of respiratory anatomy and physiology.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
