How would you differentiate between Protostomia and Deuterostomia ? |
|
Answer» Large number of animals have tube-within-tube body plan. This planis of two types `:` protostomous and deuterostomous. In protostomous plan, mouth is derived from the blastopore of the embryo and the anus is formed at the opposite end. This plan is found in most nonchrodates ( flatworms, roundworms, annelids,molluscs and arthropods) . These animals form the group termed Protostomia. In deuterostomous plan, anus develops from the blastopore and the mouth arises at the opposite end. This plan is seen in the echinoderms, hemichordates and chordates. These animals constitute the group deuterostomia. |

“All vertebrates are chordates but all chordates are not vertebrates”. Justify the statement. |
| Answer» The characteristic features of the phylum, Chordata, include the presence of a notochord and paired pharyngeal gill slits. In sub-phylum Vertebrata, the notochord present in embryos gets replaced by a cartilaginous or bony vertebral column in adults.

Statement 1 is incorrect but statement 2 is correctD. Both statements 1 and 2 are incorrect |
|
Answer» Correct Answer - A Amphibians are poikilothermic animals, i.e. they cannot regulate body temperature. Their body varies with the enviroments. Therefore, they hibernate in winter (winter sleep) to keep their body warm and aestivate in summer (summer sleep) to keep their body cool. |

| 1693. |
Assertion : Amphibians are poikilothermal Reason : Amphibians often undergoes summer sleepA. 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 Amphibai is cold blooded or ectothermal animal as its body temperature does not remain constant but fluctuates with that of enviroment. Thus it is called poikilothermal animal. In winter the temperature of the body activities ceases down. In this condition it can not hibernation in underground. Similarly during the summer it once again goes undergoes to sleep as its all body activities are slowed down due to high temperature. This is known as summer sleep. |
