Which is the National Aquatic Animal of India?
It is one of the most ancient species of aquatic mammals and is known for its intelligence, playfulness, and ability to adapt to various habitats.
The Ganges River Dolphin (also known as the Susu) is the National Aquatic Animal of India.
The national aquatic animal of India is the Ganges River Dolphin (Platanista gangetica).
Hence, option A) is the correct answer.
The river dolphin (Ganges river dolphin) is India's National Aquatic Animal. The Gangetic Dolphin is found in the river systems of the Ganges, Brahmaputra, and Indus and is considered an indicator species of the health of these rivers.
The Correct Option is A) River dolphin. The Gangetic dolphin was been declared the National Aquatic Animal of India by the Ministry of Environment and Forests on 18th May 2010.
This was done to preserve the species from extinction and to maintain the purity of the holy Ganga river as these dolphins can only survive in pure and freshwater sources.
Ganges River Dolphin, also known as Platanista Gangetica, was declared as the National Aquatic Animal of India in 2010.
Therefore, the River dolphin is the National Aquatic Animal of India.
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector
\(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
In the light of the above statements, choose the correct answer from the options given below :
The output (Y) of the given logic gate is similar to the output of an/a :
The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.
Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
