Recently, over 3000 pigs have died in the Assam due to African Swine Fever (ASF). Regarding this, consider the following statements:
1. It can be transmitted to humans through poorly-cooked pork products.
2. It can be spread through either contaminated fomites or biological vectors.
3. As of now, there is no approved vaccine against this disease.
Which of the statements given above is/are correct?
Exp:
• Statement 1 is incorrect. African swine fever (ASF) is a highly contagious haemorrhagic viral disease of domestic and wild pigs. It is caused by a large DNA virus of the Asfarviridae family, which also infects ticks of the genus Ornithodoros. It does not affect humans but can be catastrophic for pigs.
• Statement 2 is correct. There is no approved vaccine against African swine fever (unlike classical swine fever (‘Hog Cholera’) which is caused by a different virus).
• The epidemiology of ASF is complex and varies depending on the environment, types of pig production systems, the presence/absence of competent tick vectors, human behaviour, and the presence/absence of wild pigs.Routes of transmission can include:
I. direct contact with infected domestic or wild pigs;
II. indirect contact, through ingestion of contaminated material (e.g. food waste, feed, or garbage);
III. contaminated fomites, or biological vectors (soft ticks of the genus Ornithodoros) where present. Hence, statement 3 is correct.

Regarding Infrared Waves, consider the following statements:
1. Humans can detect it as heat.
2. A typical television remote control and thermal scanner use infrared energy.
3. Cool objects such as planets, cool stars, nebulae which are faint to be detected in visible light can be detected in the infrared.
Which of the statements given above is/are correct?
Exp:
• Statement 1 is correct. Infrared waves, or infrared light, are part of the electromagnetic spectrum. We encounter Infrared waves every day; our eye cannot see it, but we can detect it as heat.
• Statement 2 is correct. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.
• Some objects are so hot they also emit visible light—such as a fire does. Other objects, such as humans, are not as hot and only emit only infrared waves. Tools such as night-vision goggles or infrared cameras–allow us to "see" the infrared waves emitting from warm objects such as humans and animals.
• Thermal scanners are the latest technology being deployed to detect the coronavirus. It is a non-invasive (uses no radiation) a procedure that detects, records, and produces a careful analysis and image of skin surface temperature patterns (body heat) as a reflection of normal or abnormal human physiology.
• Statement 3 is correct. Many objects in the universe are too cool and faint to be detected in visible light but can be detected in the infrared. Scientists are beginning to unlock the mysteries of cooler objects across the universe such as planets, cool stars, nebulae, and many more, by studying the infrared waves they emit. The Cassini spacecraft captured this image of Saturn's aurora using infrared waves. The aurora is shown in blue, and the underlying clouds are shown in red.

The satellites meant for monitoring weather, communications and surveillance are stationed at geosynchronous equatorial orbit because
Correct Answer: A
Exp:
• A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth's rotation. Located at 22,236 miles (35,786 kilometers) above Earth's equator, this position is a valuable spot for monitoring weather, communications and surveillance.
• Geostationary orbits help us to find a solution to the disadvantages of LEO (low Earth orbit). Low Earth Orbit is used for things that we want to visit often with the Space Shuttle, like the Hubble Space Telescope and the International Space Station. This is convenient for installing new instruments, fixing things that are broken, and inspecting the damage. It is also about the only way we can have people go up, do experiments, and return in a relatively short time.
• There are two disadvantages of LEO:first is that there is still some atmospheric drag and the second is, unlike GEO satellites, LEO satellites fly at a much faster pace because of their proximity to Earth. Due to which weather satellite wouldn't be very effective for us in India if it does not have a long dwell time over the Indian subcontinent. Dwell time = the time a satellite sits over one part of the globe.
