Q. 33. The ‘Uttar Poorva Transformative Industrialization Scheme (UNNATI)’ aims to boost industries in which region?
Ladakh
North-Eastern states
Andaman & Nicobar
Left-Wing Extremism-affected districts
Answer:
(B) North-Eastern states
Explanation:
The UNNATI (Uttar Poorva Transformative Industrialization Scheme) was specifically approved by the Union Cabinet to promote industrial development and employment generation in India’s North-Eastern Region.
Q. 34. Which of the following cell organelles is responsible for synthesizing phospholipids and detoxifying drugs in the liver?
Mitochondria
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
Lysosome
Answer:
(C) Smooth endoplasmic reticulum
Explanation:
The Smooth Endoplasmic Reticulum (SER) lacks ribosomes on its surface and is primarily responsible for lipid (including phospholipid) synthesis and the detoxification of harmful chemicals and drugs, especially in liver cells.
Q. 35. Biofertilizers like Rhizobium are used to
Fix nitrogen
Increase pH
Kill pests
Improve drainage
Answer:
(A) Fix nitrogen
Explanation:
Rhizobium is a symbiotic bacteria found in the root nodules of leguminous plants that converts atmospheric nitrogen into ammonia (nitrogen fixation), which the plant can use for growth.
Q. 36. Stem cells can differentiate into various cell types because they are
Pluripotent
Prokaryotic
Radioactive
Apoptotic
Answer:
(A) Pluripotent
Explanation:
Stem cells (especially embryonic ones) are pluripotent, meaning they have the capacity to develop and differentiate into almost any cell type in the human body.
Q. 37. RNA interference (RNAi) technology is used in
Making antibiotics
Pest-resistant crops
Food preservation
Fermentation
Answer:
(B) Pest-resistant crops
Explanation:
RNA interference (RNAi) is a biological process where RNA molecules inhibit gene expression. It is heavily utilized in agricultural biotechnology to engineer pest-resistant crops (e.g., against nematodes).
Q. 38. Cry genes used in GM crops are originally obtained from
Agrobacterium tumefaciens
Bacillus subtilis
Bacillus thuringiensis
Escherichia coli
Answer:
(C) Bacillus thuringiensis
Explanation:
Cry (crystal) genes encode for toxins that are lethal to certain insects. These genes are originally isolated from the soil bacterium Bacillus thuringiensis (Bt).
Q. 39. Which of the following is a bioindicator of air pollution?
Earthworm
Lichen
Amoeba
Mango tree
Answer:
(B) Lichen
Explanation:
Lichens are incredibly sensitive to atmospheric pollution (especially sulfur dioxide), making them excellent, natural biological indicators of air quality.
Q. 40. The term bioremediation refers to
Use of microbes to clean up polluted sites
Use of chemicals to treat water
Use of radiation in medicine
Use of fungi to make cheese
Answer:
(A) Use of microbes to clean up polluted sites
Explanation:
Bioremediation is an environmental technology that utilizes biological agents like bacteria, microbes, or fungi to degrade, break down, or remove pollutants and toxins from soil and water.
