845. A four-chambered heart with a right systemic arch only is present in?

• A. Amphibians
• B. Reptiles
• C. Birds
• D. Mammals

Explanation: A four-chambered heart with a right systemic arch is present in BirdsBirds have a unique circulatory system in which they possess a four-chambered heart with complete separation of oxygenated (left side) and deoxygenated (right side) blood, but they have a right systemic arch. This adaptation allows them to meet the high oxygen demands of their active lifestyles, such as flying. Mammals (Option D) also have a four-chambered heart, but they typically have a left systemic arch. Amphibians (Option A) and reptiles (Option B) generally have three-chambered hearts with varying degrees of mixing of oxygenated and deoxygenated blood.

846. Which of the following is not present in the fish?

• A. Middle ear
• B. Internal ear
• C. Gills
• D. Fins

Explanation: Option A: Middle ear and external ear are not found in fishes. All tetrapods i.e. amphibians, reptiles, birds, and mammals have a middle ear with a tympanic membrane. Option B: Fishes do have internal ears that pick up sound through their body. Many fishes rely on their ears to find habitat and mates, swim and avoid predators. Option C: Gills are present in fishes as they have a major role in respiration as well as osmoregulation, excretion of nitrogenous waste, pH regulation, and hormone production. Option D: Fins are also present in fishes and they help in swimming (locomotion), balance, and stability.

847. Vertebrate with one occipital condoyle is:

• A. pigeon
• B. frog
• C. monkey

• A. Typhlosole
• B. Intestinal caeca
• C. Esophagus
• D. Pharyngos mass

Explanation: The pharynx of an earthworm, particularly the pharyngeal mass, is where various digestive enzymes are secreted. These include protease, which breaks down proteins into amino acids, and mucin, which aids in softening the food. The other structures mentioned, such as the typhlosole, intestinal caeca, and esophagus, have roles in the digestive process but are not primarily responsible for enzyme production. The typhlosole increases absorptive surface area, the intestinal caeca have a minor role in digestion, and the esophagus is merely a passageway for food.

849. Organs of locomotion in earth worm are:

• A. Papillae
• B. Setae
• C. Pseudopodia
• D. Cuticle

Explanation: Organs of locomotion in earth worms are setae. Setae are present on parapodia on the body wall or embedded in sacs.
