How cockroach can live without head ?

A cockroach can live for a week without its head. Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst.

Why do flamingos stand on one leg?

Flamingos often stand on one leg, the other leg tucked beneath the body. The reason for this behaviour is not fully understood. Recent research indicates that standing on one leg may allow the birds to conserve more body heat, given that they spend a significant amount of time wading in cold water.

Can a shark swim backwards?

Unlike fish, sharks cannot stop suddenly or swim backwards. A shark's pectoral fins cannot bend upwards like a fish, limiting its swimming ability to forward motion. If a shark needs to move backwards, it uses gravity to fall, not swim backwards.

What are vaccine passports?

News- Vaccine passports for international travel? Why you may need one soon?

The idea is modelled on the proof of vaccination that several countries required even before the pandemic. Travellers from many African countries to the US or India are required to submit proof that they have been vaccinated against diseases such as yellow fever.

Even though the nomenclature comes from passports, most vaccine passports have been envisaged as digital documents. They are supposed to function as proof that the holder has been vaccinated against Covid-19 and is, therefore, “safe”.

What is 'Twilight Zone' of oceans?

Twilight zone in oceans is the part at the depth of 200 to 1000 metres. These depths are given such a name because water at these depths receive less sunlight. A study by Cardiff University has revealed that global warming is adversely affecting life in the twilight zone of oceans.

As one goes deeper in ocean, organisms obtain nutrition via different modes. One of them is the 'marine snow'. Marine snow is simply food and nutrient particles sinking deeper in water after they fall into it from air.

Will the coronavirus ever go away?

No one knows for sure. Scientists think the virus that causes Covid-19 may be with us for decades or longer, but that doesn't mean it will keep posing the same threat.

The virus emerged in late 2019 and it's difficult to predict how it will behave over the long term. But many experts believe it's likely the disease will eventually ease from a crisis to a nuisance like the common cold.

That would happen as people build up immunity over time, either through infection or vaccination. Other viruses have followed a similar path.

The 1918 flu pandemic could also offer clues about the course of Covid-19.

What is Sandstorm or Dust Storm?

News: Beijing witnesses worst sandstorm in a decade, causing severe air pollution

A dust storm, also called sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another.

Drylands around North Africa and the Arabian peninsula are the main terrestrial sources of airborne dust.

The term sandstorm is used most often in the context of desert dust storms, especially in the Sahara Desert, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles are blown closer to the surface. 🌪
