Only d is wrong
Explanation:
(a) correct. Karnataka has the world’s largest population of lion-tailed macaques (LTMs) with 41 groups of 730 individuals, according to a study by the Karnataka Forest Department and Coimbatore-based Salim Ali Centre for Ornithology and Natural History (SACON).

(b) Correct. Lion-Tailed Macaques are indeed indicators of evergreen forests and are known for preferring the canopy, making them rarely visible on the ground. “It revealed that Uttara Kannada has been a significant and potential site for the conservation of LTMs, considering the sizable canopy and undisturbed habitat as compared to the north of Sharavathi,”
(c) Correct. This statement accurately reflects the recent conservation efforts focusing on the Sharavathi Valley Sanctuary, particularly in the Shivamogga circle.
This is the first integrated LTM assessment exercise for the Sharavathi Valley Sanctuary, covering both Canara and Shivamogga circles. Earlier, the study focussed only on Canara circle. LTMs are the indicators of evergreen forests as they prefer canopy and are rarely seen on ground.

(d) Incorrect. Lion-Tailed Macaques are not extinct; they are an endangered species endemic to the Western Ghats but still have surviving populations.
The lion-tailed macaque is an endangered primate endemic to Western Ghats.

The report conducted by Salim Ali Centre for Ornithology and Natural History, Coimbatore and the Karnataka Forest Department states many anthropogenic activities have been a major concern in the area.
Karnataka has the world’s largest population of lion-tailed macaques (LTMs) with 41 groups of 730 individuals, according to a study by the Karnataka Forest Department and Coimbatore-based Salim Ali Centre for Ornithology and Natural History (SACON).
29. Go through the following four statements given below:
(a) Root pressure provides a moderate push in the overall process of water transport.
(b) Most plants meet their water needs by transpiration pull.
(c) The greatest combination of root pressure may be to re-establish the continuous chains of water molecules in the xylem vessel which often break under enormous tension created by transpiration.
(d) Guttation is the cause of transpiration pull.
Choose the correct answer from the options given below:
(a) and (b)
(b) and (c)
(a), (b), and (c)
(a), (b), (c), and (d)
Answer:(a), (b), and (c)
Explanation:
(a) Root pressure provides a moderate push in the overall process of water transport: Correct. Root pressure helps in pushing water up through the roots, but it is not the primary mechanism for water transport in tall plants.
(b) Most plants meet their water needs by transpiration pull: Correct. Transpiration pull, due to the evaporation of water from leaves, creates a negative pressure that helps in drawing water upwards through the xylem.
(c) The greatest combination of root pressure may be to re-establish the continuous chains of water molecules in the xylem vessel which often break under enormous tension created by transpiration: Correct. Root pressure can help to re-establish water columns in xylem when breaks occur, but it is not the primary driver of water transport.
(d) Guttation is the cause of transpiration pull: Incorrect. Guttation is the exudation of water droplets from the edges of leaves, typically occurring at night, and is not related to the transpiration pull which occurs due to water evaporation.
Therefore, the correct answer is (3) (a), (b), and (c).
34. Which of the following are true about nanomaterials?
(a) The properties strongly depend on the surface atoms.
(b) They have a large surface area.
(c) Nanoparticles have typical sizes > 100 nm.
(d) We cannot see particles of nanomaterials from the naked eye.
Select the correct answer using the code given below:
(a), (b), and (c)
(a), (c), and (d)
(b), (c), and (d)
None of the above
Answer:3. None of the above
Based on this, the correct answer is:
(a), (b), and (d)
Explanation:
Let's assess each statement about nanomaterials:
(a) The properties strongly depend on the surface atoms.
Correct. For nanomaterials, surface-to-volume ratio is significant, and many of their unique properties arise from the surface atoms.
(b) They have a large surface area.
Correct. Nanomaterials have a large surface area relative to their volume due to their small size.
(c) Nanoparticles have typical sizes > 100 nm.
Incorrect. Nanoparticles typically have sizes ranging from 1 nm to 100 nm. Particles larger than 100 nm are generally not classified as nanomaterials.
(d) We cannot see particles of nanomaterials from the naked eye.
Correct. Nanoparticles are so small that they cannot be seen with the naked eye.
Based on this, the correct answer is:
(a), (b), and (d)
Given that option (c) is incorrect
46. Which of the following statements are correct with reference to the Blue Flag Certification?
(a) This certification is issued to beaches, estuaries, and deltas.
(b) The certification is issued based on 33 criteria and it is an internationally recognized eco-label.
(c) BEAMS is India's own eco-label for beaches launched in 2020.
(d) Two sites from Karnataka, Kasarkodi Beach and Padubidri Beach, have received Blue Flag Certification.
Choose the correct answer from the options given below:
All of the above
(a), (b), and (c) only
(c) and (d) only
(a), (b), and (d) only
Answer: All of the above
Explanation:
(a) This certification is issued to beaches, estuaries, and deltas: Correct. The Blue Flag certification is typically awarded to beaches and marinas that meet stringent environmental, educational, safety, and accessibility criteria.
The Blue Flag certification is an eco-label certification awarded to beaches, marinas, and sustainable boat tourism operators that meet some prescribed requirements. Blue Flag Certification provides insight into the health of the coastal ecosystem. Blue flag certification is given by international jury consisting of members of the United Nations Environment Programme (UNEP), United Nations World Tourism Organisation (UNWTO), Denmark-based NGO Foundation for Environmental Education (FEE), and International Union for Conservation of Nature (IUCN).
It is an internationally recognised eco-label that is accorded based on 33 criterias. These criterias are divided into 4 major heads namely,
Environmental education and information
Bathing water quality
Environmental management
Conservation and safety services in the beaches
(b) The certification is issued based on 33 criteria and it is an internationally recognized eco-label: Correct. The Blue Flag certification is awarded based on compliance with 33 criteria covering environmental education, water quality, environmental management, and safety.
(c) BEAMS is India's own eco-label for beaches launched in 2020: correct. BEAMS (Beach Environment & Aesthetic Management Services) is a project under the Integrated Coastal Zone Management (ICZM) aimed at sustainable development, but it is not an eco-label similar to Blue Flag.
On the lines of Blue Flag certification, India has also launched its own eco-label BEAMS (Beach Environment & Aesthetics Management Services) in 2020.
(d) Two sites from Karnataka, Kasarkodi Beach and Padubidri Beach, have received Blue Flag Certification: Correct. These two beaches in Karnataka have been awarded the Blue Flag certification for meeting the required environmental and safety standards.
Kasarkod and Padubidri are two of the most mesmerizing, clean, and well-maintained beaches in Karnataka. The experience is quite different from other beaches, the environment is much more peaceful and serene, truly deserving the Blue Flag label.
