Q71. Consider the following animals: 1. Sea cow 2. Sea horse 3. Sea lion Which of the above is/are mammal/mammals?
Explanation
Mammals are warm-blooded animals with hair and vertebrates, or backbones. Unlike other classes of animals, female mammals produce milk to nourish their young. Almost all mammals give birth to live young (except for the platypus and echidna, which lay eggs). Statements 1 is correct: Dugong belongs to the order Sirenia and is a marine mammal found in warm coastal waters. The Dugong (Dugong dugon) is the sea cow found in Indian waters. They are herbivorous and are known for their gentle nature. They give birth to live young and nurse them with milk, characteristic of mammals. They are found in over 30 countries and in India are seen in the Gulf of Mannar, Gulf of Kutch, Palk Bay, and the Andaman and Nicobar Islands.
Statement 2 is incorrect: The Sea Horse is not a mammal but a fish, part of the genus Hippocampus. Despite its name, the sea horse is a small marine creature, known for its unique horse-like head and upright swimming posture. It is an ectother-mic species (cold-blooded) and lays eggs, unlike mammals which give birth to live young Statements 3 is correct: Sea Lion is a mammal. It belongs to the family Otariidae and is a type of pinniped (a group of fin-foot-ed mammals). Sea lions are marine mammals that live in coastal areas and are known for their external ear flaps and ability to "walk" on land using their front flippers.

Q72. Consider the following organisms: 1. Agaricus 2. Nostoc 3. Spirogyra Which of the above is/are used as biofertilizer/biofertilizers?
Explanation
Bio-fertilizers are living or biologically active products or microbial inoculants of bacteria, algae and fungi (separately or in combination) which are able to enrich the soil with nitrogen, phosphorus, organic matter etc.
Statement 1 is incorrect: Agaricus refers to a genus of fungi, commonly known for species like Agaricus bisporus, the common button mushroom. While it is used in culinary and medicinal contexts, it is not used as a biofertilizer. They are not involved in nitrogen fixation or other activities that promote soil fertility, which are characteristic of biofertilizers.
Statement 2 is correct: Nostoc is a genus of cyanobacteria (blue-green algae) that can fix atmospheric nitrogen. It is often used as a biofertilizer because of its ability to enhance soil fertility by converting atmospheric nitrogen into a form that plants can utilize. Nostoc is commonly found in rice paddies and is used to improve nitrogen content in the soil, especially in organic farming.
Statement 3 is incorrect: Spirogyra is a genus of green algae that primarily plays a role in freshwater ecosystems. While it is important for oxygen production and can contribute to the aquatic environment, it is not used as a biofertilizer. Unlike Nostoc, Spirogyra does not have significant nitrogen-fixing capabilities.

This rift valley naturally channels the river westward, distinguishing it from most other peninsular rivers that flow eastward.
Statement 2 is incorrect: Though the Narmada does flow between the Vindhya and Satpura ranges but it not the cause of its westward flow. The ranges themselves are remnants of older folded mountains.
Statement 3 is incorrect: While most rivers in the Indian peninsula flow eastward towards the Bay of Bengal. This is due to the region’s natural slope to the west from Central India. But the Narmada River’s westward course is dictated by its unique geological setting within a rift valley.
