7Stem cells are important in medicine because:
Answer: B - They can differentiate into various cell types
Stem cells are undifferentiated cells capable of self-renewal and differentiation into specialised cell types. Embryonic stem cells are pluripotent (can form any body cell). Adult stem cells are multipotent (limited range). Induced Pluripotent Stem Cells (iPSCs) are reprogrammed adult cells. Medical applications include treatment of blood disorders, spinal injuries and diabetes.

9Photovoltaic cells convert which energy into electricity?
Answer: C - Solar (light) energy
Photovoltaic (PV) cells convert solar light energy directly into electricity through the photovoltaic effect - when photons (light particles) knock electrons loose from atoms in a semiconductor material (usually silicon), generating an electric current. India has one of the world's largest solar power programmes under the National Solar Mission.

10The Human Genome Project was completed in:
Answer: B - 2003
The Human Genome Project (HGP) was an international scientific research project that sequenced and mapped all human genes (approximately 20,000-25,000 genes, 3 billion base pairs). Initiated in 1990, it was formally completed in April 2003. It has revolutionised medicine, enabling genetic testing, personalised medicine and understanding of genetic diseases.
