If a live earthworm is pricked with a needle on its outer surface without damaging its gut, the fluid that comes out isA. excretory fluidB. coelomic fluidC. haemolymphD. slimy mucus |
|
Answer» Correct Answer - B The body cavity of earthworm is true coelom(schizocoel) as it is formed by the division of mesoderm. The coelom is filled with milky, alkaline coelomic fluid, which contains different types of corpuscles. Thus, if alive earthworm is prickled with a needle on its alive earthworm is prickled with a needle on its outer surface, the coelomic fluid will come out. Excretory fluids Excretory system regulate the chemical composition of body fluids by removing metabolic waste substances. Haemolymph It is a fluid in the open circulatory system of arthropods, e.g. spiders, crustaceans etc. It is analogous to the fluids and cells making both blood and interstitial fluid. slimy mucus Mucus trap bacteria cell debris and prevents it from entering into lungs and in their body parts. |

Assertion : Endostyle is present at the pharyngeal groove of the midventral wall of the pharynx of Amphioxus. Reason : Endostyle has an important role in respiration.A. If both the assertion and the reason are true and the reason is a correct explanation of the assertionB. If both the assertion and reason are true but the reason is not a correct explanation of the assertionC. If the assertion is true but the reason is falseD. If both the assertion and reason are false |
|
Answer» Correct Answer - C In the mid ventral wall of pharynx is a shallow groove called endostyle. The endostyle is lined with glands cells which secrets mucus. The larval endostyle is lost during metamorphosis of lamprey, it contributes to the formation of a thyroid gland in the adult. Like thyroid it concentrates radioactive iodive in itself. Similar endostyle is found in urochordate and the ammocoete larve of lampreys. |

Assertion : Respiration in Amphioxus is done by both water and blood. Reason : Amphioxus is aquatic and possesses bloodA. If both the assertion and the reason are true and the reason is a correct explanation of the assertionB. If both the assertion and reason are true but the reason is not a correct explanation of the assertionC. If the assertion is true but the reason is falseD. If both the assertion and reason are false |
|
Answer» Correct Answer - A In Amphioxus, some exchange of `O_(2)` and `CO_(2)` occurs between the water current and blood through the gillclefts, but this appears doubtful since the blood contains no respiratory pigment. The pharyngeal wall of Branchiostoma is richly vascular cavity brings `O_(2)`. The blood flows so close to the surface that some exchange of gases occurs over the whole surface of the body and particularly in the walls of atrium. |

Assertion : Amphioxus has a simple organization compared to vertebrates. Reason : Many important craniate structure are lacking in Amphioxus.A. If both the assertion and the reason are true and the reason is a correct explanation of the assertionB. If both the assertion and reason are true but the reason is not a correct explanation of the assertionC. If the assertion is true but the reason is falseD. If both the assertion and reason are false |
|
Answer» Correct Answer - A Amphioxus is devoid of heat, head kidneys and paired limbs. Paired sense organs are absent here receptors are of primitive types. A complete notochord is persistant with no vertebral column. This shows that it has a simple organization compared to vertebrates because many important craniate structures are lacking in it. But it is definitely a simple chordate such as a notochord, dorsal hollow nerve cord, and gill clefts. |
