Haematology is the branch of medicine concerned with the study of blood, blood-forming organs, and blood diseases. It covers red and white blood cells, platelets, bone marrow, and conditions like anemia, leukemia, and clotting disorders.

Phycology (or algology) is the branch of biology that studies algae, including their classification, physiology, ecology, and uses. Algae range from microscopic diatoms to giant kelp forests and are crucial for oxygen production and aquatic ecosystems.

Mycology is the branch of biology concerned with the study of fungi, including their genetics, biochemical properties, taxonomy, and uses. Fungi include yeasts, molds, mushrooms, and are essential for decomposition, medicine (antibiotics), and food production.

Vinod Dham (often spelled Dahm) is known as the 'father of the Pentium chip' for his key role in leading the Pentium processor development team at Intel. Sabeer Bhatia founded Hotmail, Vinod Khosla co-founded Sun Microsystems, and Ranchor Das is not a known figure in tech.

Vinod Khosla was a co-founder of Sun Microsystems in 1982 along with Scott McNealy, Bill Joy, and Andy Bechtolsheim. Vinod Dahm worked on the Pentium chip, and the other names listed are not Sun Microsystems founders.

Albert Einstein acknowledged the foundational contribution of Indian mathematicians who developed the decimal numeral system and concept of zero, which are essential to all modern mathematics and science. This quote recognizes that without place-value notation and zero, complex calculations and scientific discoveries would be nearly impossible.

Sabeer Bhatia, an Indian-American entrepreneur, co-founded Hotmail in 1996, which became the world's first web-based email service. Hotmail revolutionized communication by allowing users to access email from any computer with internet access, and was later acquired by Microsoft for $400 million.

India, along with Japan, is among the few countries that have developed supercomputers indigenously (without importing complete systems). India's PARAM series and Japan's various supercomputers demonstrate indigenous capability in high-performance computing, placing both nations in an elite technological group alongside the United States.

Apiculture is the honey industry - beekeeping for honey and other products. Arachnology is spider study (not option A), Herpetology studies frogs (option B is incorrect), and Ornithology studies birds (option D is incorrect).

Ornithology is the scientific study of birds. Ichthyology studies fish (option B incorrect), Sericulture is silk production (option C incorrect), and Craniometry studies skulls (option D incorrect).

Araneology is the study of spiders. Ichthyology studies fish (option A), Pomology studies fruits (option B), and Herpetology studies frogs (option C). The term comes from 'araneae' - the spider order.

Batracology is derived from Greek 'batrachos' meaning frog, referring to the scientific study of frogs and other amphibians. Ornithology studies birds (B), seismology studies earthquakes (A), and cryptography deals with secret writing (D).

Pisciculture comes from Latin 'piscis' meaning fish and refers to fish farming or breeding. Pedology studies soils (A), sericulture is silk production (C), and pomology studies fruits (D).

Earth is visible from space because it reflects sunlight - it doesn't produce its own light. The Sun is the closest star to Earth, and its light reflects off Earth's surface (oceans, land, clouds) back to observers. Option A is wrong because Earth doesn't generate light. Option B is incorrect - crust heat doesn't produce visible light. Option D uses 'refracted' incorrectly - reflection is the correct phenomenon.
