3. The Genetic Engineering Appraisal Committee (GEAC) functions under which ministry?
Correct Answer: B [Ministry of Environment, Forest, and Climate Change ]
Notes:
The Union Ministry of Environment, Forest, and Climate Change has amended the rules for selecting experts for the Genetic Engineering Appraisal Committee (GEAC). GEAC is a statutory committee under the 1989 rules for hazardous and genetically engineered organisms framed under the Environment (Protection) Act, 1986. It was renamed from the Genetic Engineering Approval Committee to Genetic Engineering Appraisal Committee in 2010. GEAC operates under the Ministry of Environment, Forest, and Climate Change (MoEF&CC).

4.Which institute has recently developed bacteria to combat soil pollution and boost agriculture?
Correct Answer: C [IIT Bombay]
Notes:
IIT Bombay researchers developed a solution to tackle soil pollution using bacteria that consume toxic pollutants and produce essential nutrients. These bacteria degrade harmful substances, boost plant growth hormones, inhibit harmful fungi, and improve nutrient availability for plants. This innovation can reduce reliance on chemical pesticides and enhance soil health and fertility. The bacteria, mainly from the genera Pseudomonas and Acinetobacter, were isolated from highly toxic environments and contaminated soils. They effectively break down aromatic pollutants like carbaryl, naphthalene, and phthalates, commonly found in pesticides and industrial by-products. The research offers an eco-friendly alternative to expensive traditional soil remediation methods.

5. The Brazilian Velvet Ant species is mainly found in which habitat?
Correct Answer: B [Shrub desert ]
Notes:
Scientists discovered that the dark markings on the Brazilian Velvet Ant absorb nearly all visible light, reflecting less than 1%. Velvet ants, a group of parasitic wasps, are known for bright coloration and a powerful sting. They are wingless, with distinct black and white markings, and are mainly found in Brazil’s Caatinga shrub desert. Velvet ants are highly mobile, covering long distances to find hosts, and are most active in early morning and late afternoon. The ultra-black pigmentation helps them absorb light and enhances their unique appearance in the animal kingdom.
