Introduction:
Lymphatic system comprises of cells, tissues and other organs which defend our body against infections and disease. It is also comprised of lymph-a clear fluid which is found outside the cells. Lymphatic system has lymphatic capillaries, vessels, ducts, and trunks. Lymphatic system is also comprised of lymphatic tissues or organs like, tonsils, lymph nodes and nodules, spleen, and MALT.

Answer to Problem 1DYKB
Correct answer:
The lymphatic system is a part of the circulatory system and immune system that have interconnected lymphatic vessels which contain a clear fluid called lymph. Therefore, option b. is correct.
Explanation of Solution
Reason for the correct statement:
Option b. is given as “cardiovascular and immune”. The circulatory and immune systems are supported by the lymphatic system. The lymphatic fluid is consists of immune system cells that protect against infection and also the circulatory fluid blood is filtered by the spleen. Hence, immune and cardiovascular systems are the body systems which are supported by the lymphatic system.
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as “cardiovascular and urinary”. Lymphatic system supports cardiovascular system but does not have any role with the urinary system. Hence, option a. is incorrect.
Option c. is given as “respiratory and cardiovascular”. Lymphatic system supports cardiovascular system but it does not supports the respiratory system. Hence, option c. is incorrect.
Option d. is given as “respiratory and urinary”. Lymphatic system supports circulatory and immune systems in body but does not have any function in either respiratory or urinary system. Hence, option d. is incorrect.
Hence, options a., c., and d. are incorrect.
Lymphatic system supports both circulatory and immune systems as they are interconnected. Lymphatic system provides immunity to cells, tissues and other organs which helps to defend the body against infections and disease. Lymphatic system also returns the fluid leaked from the blood back into the circulation.

How so?arrow_forwardUse 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. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above.

- 24) 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. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group?

Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forward
