A And R type MCQ A = The body of the Aschelminthes is circular in cross-section. R = The also known as round worms
Both the assertion and reason are true, and the reason correctly explains the assertion. The body of Aschelminthes (Nematoda) is circular in cross-section, which is why they are also known as roundworms.
A And R type MCQ A = Fertilisation is internal and development maybe direct or indirect in round worm. R = Females are longer than males
Both the assertion and reason are true. Fertilization is internal and development may be direct or indirect in roundworms (Nematoda). Additionally, females are generally longer than males, but this reason does not directly explain the assertion. Hence, both statements are true but the reason does not explain the assertion.
A And R type MCQ A = Arthropods have Respiratory organs like gills, book gills, book lungs or tracheal system. R = Excretion takes place through malpighian tubule is in Arthropods.
Both the assertion and the reason are true. Arthropods do have respiratory organs like gills, book gills, book lungs, or a tracheal system. Excretion in arthropods occurs through Malpighian tubules. However, the reason is not the correct explanation of the assertion because the respiratory and excretory systems are separate functions.
A And R type MCQ A = The space between the hump and the mantle is called the mantle cavity in which feather like gills are present. R = They have respiration and excretory functions.
Both the assertion and the reason are true, and the reason correctly explains the assertion. In mollusks, the space between the hump and the mantle is called the mantle cavity, which contains feather-like gills. These gills are responsible for respiration and also play a role in excretion.
A And R type MCQ A = Water vascular system is found in Aves R = They help in blood circulation
Both the assertion and the reason are false. The water vascular system is not found in Aves (birds); it is characteristic of Echinoderms like starfish. Additionally, the water vascular system is not involved in blood circulation but rather in locomotion, feeding, and respiration in echinoderms.
A And R type MCQ A = Excretory organs is gills in balansoglossus R = Respiration takes place through proboscis
In Balanoglossus, the excretory organs are not gills; instead, they possess glomerulus for excretion. Additionally, respiration in Balanoglossus occurs through gill slits and not through the proboscis. Therefore, both the assertion and the reason are false.
A And R type MCQ A = Cyclostomata have an elongated body bearing 6-15 pairs of gill slits. R = They help in digestion
Cyclostomata, such as lampreys and hagfishes, do have an elongated body with 6-15 pairs of gill slits, but these gill slits are not involved in digestion. They are involved in respiration. Thus, the assertion is true, but the reason is false.
A And R type MCQ A = Heart is usually three chambered in reptillia. R = Heart is two chambered in crocodiles
A And R type MCQ A = The hind limbs generallyhave scales and are modifided for walking, swimming or clasping. R = The short bones are hollow with posseses air cavities.
Symmetry is cnidaria is (AMW-2009)
Cnidarians, such as jellyfish, corals, and sea anemones, exhibit radial symmetry. This means their body plan is arranged around a central axis, allowing them to interact with their environment from all directions equally. Hence, the correct option is o1: Radial.
