Textbook Question

Chapter 33, Problem 1SA

All vertebrates have _______ .

a. a closed circulatory system
b. a two-chambered heart
c. lungs
d. hemolymph

Expert Solution & Answer

Summary Introduction

Introduction:

The vertebrates are the organisms that are characterized by the presence of the solid backbone which is a bony structure that extends from the neck to the abdomen. It is absent in the invertebrates which makes them easily distinguishable from the vertebrates.

Answer to Problem 1SA

Correct answer:

All vertebrates have closed circulatory system. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as, “closed circulatory system.”

The invertebrates have an open circulatory system in which the blood is present freely in the body cavity while in the vertebrates, it is confined to the blood vessels.

Reason for incorrect answer:

Option b. is given as, “two-chambered heart.”

The vertebrates can have two, three or four-chambered heart. The number of chambers in the heart is not the defining feature of vertebrates. Hence, option b. is incorrect.

Option c. is given as, “lungs.”

Not all vertebrates have lungs. The fishes respire through gills, and they are members of vertebrates. So, the presence of the lungs does not define the vertebrates. Hence, option c. is incorrect.

Option d. is given as, “hemolymph.”

Hemolymph is the mixed fluid present in animals like Arthropods and Molluscs. It is an important constituent of their unique open circulatory system. The hemolymph helps to exchange the nutrients and the waste products from the body. It is not present in vertebrates. Hence, option d. is incorrect.

Hence, the options b., c., and d. are incorrect.

Conclusion

The presence of a closed circulatory system is a unique character of vertebrates. The vertebrates contain blood vessels, capillaries and a pumping organ known as the heart in their circulatory system. Thus, the correct option is a.

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:
