Answer to Problem 1TY

Correct answer: The hemolymph is the fluid that circulates in the body cavity of the animals like Arthropods and Molluscs. This cavity is called hemocoel. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

The hemolymph enters the blood vessels in the Molluscs, while in Arthropods it directly enters the heart of the organism.

Option b. is given as, “is a mixture of fluid in blood vessels and the hemocoel”.

Hemolymph is the fluid present in the cavity called the hemocoel in Arthropods. In Molluscs, it enters the heart through blood vessels. Hence, the correct answer is option b.

Reasons for the incorrect answer:

Option a. is given as, “does not contain blood cells”.

Hemolymph is the fluid that contains the blood cells. It is required to transport nutrients and waste materials in the body of an animal. Hence, option a. is incorrect.

Option c. is given as, “circulates through closed circulatory systems only”.

The hemolymph is a feature of the open circulatory system present in the Arthropods and Molluscs. Hence, option c. is incorrect.

Option d. is given as, “functions only in defense of the body and not transport”.

Hemolymph is used to transport waste material to the excretory organs and nutrients to the rest of the body. Hence, option d. is incorrect.

Option e. is given as, “does not pass through a heart”.

The hemolymph enters the heart directly in Arthropods, and through blood vessels in Molluscs. Hence, option e. is incorrect.

Hence, the options a., c., d., and e. are incorrect.

Conclusion

The Arthropods and the Molluscs have a unique feature of an open circulatory system where the hemolymph is present freely in the hemocoel (body cavity) and is not confined to unique vessels.

*Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
