Introduction: The distribution of nutrients and the transportation of gases take place by using the body fluid. A pumping organ pushes the fluid to various parts of the body. The presence of hemolymph is observed in the organisms having an open circulatory system.
Answer to Problem 1TY
Correct answer: The hemolymph differs from the blood as it is a mixed fluid present in the hemocoel. Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
In an open circulatory system, the combination of interstitial fluid that surrounds the cells gets mixed with the fluid carried by the blood vessels in a single chamber. The mixed fluid is known as hemolymph and the body cavity is known as hemocoel.
Option b. is given as “is a mixed fluid found in the hemocoel”.
The blood differs from the hemolymph. Blood circulates in the blood vessels while hemolymph is a mixed fluid present in the hemocoel. Hence, the correct answer is option b.
Reason for incorrect answer:
Option a. is given as, “does not contain blood cell”.
Hemolymph is responsible for the transportation of the gases to various organs of the body. The transportation of gases takes place by blood cells. Hence, option a. is incorrect.
Option c. is given as, “circulates through the closed circulatory system only”.
The hemolymph is the combination of blood and lymph. The fusion of both fluids takes place in the open circulatory system inside the hemocoel. Hence, option c. is incorrect.
Option d. is given as, “functions only in defense of the body and not transport”.
The hemolymph is responsible for the transportation of gases to the tissues. The transportation of gases is also a function of hemolymph. Hence, option d. is incorrect.
Option e. is given as, “does not pass through the heart”.
Each body fluid needs pressure for its circulation in the body, which is provided by the heart. Every circulation that occurs in the body of the organism will pass through the heart. Hence, option e. is incorrect.
Hence, the options a., c., d., and e. are incorrect.
Hemolymph is a mixed fluid found in the hemocoel which differs from the blood.

- Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to. What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?arrow_forwardDoes the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo? Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?arrow_forwardUsing quail and chicken embryos, what kind of experiment would you conduct to test if rib forming somites have their axial identity specified before segmentation? How do we know this phenotype is due to axial identity being specified before segmentation and not due to our experimental method?arrow_forward

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid.

- You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?arrow_forwardYou decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.arrow_forwardYou implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forward
