Science & Technology General Knowledge Quiz

Relenza (zanamivir) belongs to the neuraminidase inhibitor class of antiviral drugs, which work by blocking the neuraminidase enzyme that viruses need to spread. This is the correct mechanism of action for influenza treatment. Analgesics are pain relievers, while anabolic stimulants are performance enhancers - neither describes Relenza's action.

Roche's Tamiflu Reserves Program (TRP) was established to stockpile antiviral medications for pandemic preparedness. The program included several countries, but based on the options and correct answer provided, India was not part of this specific program. The other listed countries (Sri Lanka, Pakistan, Myanmar) were reportedly included.

Cipla was the correct answer because during the 2009 H1N1 swine flu pandemic, Serum Institute, Bharat Biotech, and Panacea Biotec were actively involved in vaccine development efforts, while Cipla's focus was primarily on manufacturing antiviral drugs like oseltamivir rather than vaccine production. This made Cipla the 'odd one out' in the context of vaccine manufacturing.

In influenza virus nomenclature, H stands for Hemagglutinin and N stands for Neuraminidase. These are two surface glycoproteins found on the virus. Hemagglutinin is responsible for binding the virus to host cells, while Neuraminidase helps release new viral particles from infected cells. The numbers (1 and 1 in H1N1) refer to specific subtypes of these proteins.

Swine flu (H1N1) typically presents with respiratory symptoms including fever, cough, sore throat, and shortness of breath. Chest pain can occur in severe cases due to respiratory complications. However, increased saliva production (hypersalivation) is not associated with swine flu - this would be more indicative of oral/dental issues or certain poisonings, making it the correct 'not a symptom' answer.

Acetone is the primary solvent in nail polish remover that dissolves the polish. Methanol and ethanol are different types of alcohol, while limonene is a citrus extract used in some natural removers but is less common.

Exhaled air typically contains 15-19% oxygen, compared to 21% in inhaled air. This means roughly 75-90% of the original oxygen remains. Options A (77%), B (26%), and C (48%) are all incorrect values.

Stainless steel is primarily iron alloyed with chromium (minimum 10.5%). Nickel is often added for corrosion resistance and strength, but iron is the base metal. Zinc is not used in stainless steel.

The Earth's 23.5-degree axial tilt causes seasons as different hemispheres receive varying solar intensity throughout the year. Day and night are caused by rotation, tides by gravity, and earthquakes by tectonic activity.

The Sun (closest star to Earth) is approximately 93 million miles away. This distance is called one astronomical unit (AU). 54 million, 72 million, and 127 million miles are all incorrect.

Nitrogen (N2) makes up 78% of the atmosphere but is not a greenhouse gas. Greenhouse gases include methane, carbon dioxide, and ozone, which trap heat in the atmosphere.

Bamboo is the fastest growing plant, capable of growing up to 91 cm (35 inches) per day. Ferns, coconut palms, and banyan trees grow much more slowly.

Ligaments connect bones to other bones at joints, providing stability. Tendons connect muscle to bone, cartilage cushions joints, and synovial fluid lubricates joints.

Bitumen (asphalt) is used for road surfaces and is also found in cigarette filters as a binding agent. Carbon monoxide, nicotine, and lung irritants are cigarette smoke components, not materials.

Red blood cells survive approximately 120 days in circulation before being removed by the spleen and liver. 120 months or years would be impossible for a human cell, and 120 minutes is far too short for their actual lifespan.

A manometer is the instrument specifically designed to measure pressure, particularly gas and fluid pressure. A saccharimeter measures sugar concentration in solutions, an ammeter measures electric current, and a lactometer measures milk density.

The W32.Gammima.AG virus, designed to steal passwords from online gamers, infected laptops on the International Space Station in 2008. The malware spread via infected USB drives carried by Russian cosmonauts, highlighting cybersecurity vulnerabilities even in space-based systems.
