Respiration is a process, in which food is broken down into simpler components by releasing energy. The respiratory system consists of organs that participate in the exchange of gases. Respiration includes two processes; breathing (external respiration) and cellular respiration (internal respiration). The organs included in the respiratory system are lungs, trachea, nasal cavity, nose, pharynx, larynx, bronchi, bronchioles, and alveoli.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Expert Solution & Answer

Answer to Problem 1DYB

Correct answer:

Respiration normally requires nervous system, muscular system, and respiratory system. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

Option d. is given as “All of these are correct”. Respiration involves inhalation and exhalation. Lungs, nostrils, nasal cavity, and windpipe are parts of the respiratory system that are involved in respiration. Respiration also involves muscular system. Muscle cells function in the contraction and relaxation of the diaphragm and thoracic cavity. Muscle contraction is promoted by stimuli. These stimuli are transmitted through neurons. Hence, respiration normally requires nervous system, muscular system, and respiratory system.

Hence, option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “respiratory system”. Apart from the respiratory system, respiration also requires muscular and nervous system. Hence, option a. is incorrect.

Option b. is given as “muscular system”. Apart from muscular system, respiration also requires nervous system and respiratory system. Hence, option b. is incorrect.

Option c. is given as “nervous system”. Apart from the nervous system, respiration also requires muscular system and respiratory system. Hence, option c. is incorrect.

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

Conclusion

Respiration involves the functioning of the respiratory system, nervous system, and muscular system. All these systems function simultaneously to perform respiration.

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:
