How do Plants Breathe?

-
Like any other living organism, plants also breathe. They take in oxygen and release carbon dioxide by the process of respiration. The oxygen taken in is used for breaking down sugars that the plant makes during photosynthesis, and energy and carbon dioxide are released. This energy is used by plant for its growth and reproduction. About 40 per cent of the energy released is used up and the rest is lost as heat.

What Would Permanent Daylight Saving Time Change?

Permanent daylight saving time would mean keeping clocks one hour ahead of standard time throughout the year instead of moving them forward in spring and backward in autumn. The idea is intended to provide more daylight during the evening, but it would also produce later sunrises, especially during winter. Supporters argue that a fixed clock would remove the disruption caused by changing time twice a year. Longer evening daylight may also support outdoor activities, shopping, tourism, and after-work recreation. However, the amount of economic or energy benefit remains debated, and daylight saving time does not create additional sunlight—it only changes how the hours of daylight are labeled. Sleep researchers and health organizations have raised concerns about permanent daylight saving time because darker winter mornings can affect sleep schedules, school commutes, and the body’s natural circadian rhythm. Some experts therefore support permanent standard time instead, while others focus...

T he black box is the common name for the flight data recorder, a device carried in an aircraft. Its purpose is to give the cause of faults if these develop in flight . It gives information about a plane's heading, height, air speed, rate of descent , etc. This recorder is encased in a crash proof, fireproof, floatable box. In case of a casualty, the black box remains safe and is recovered later. The information are recorded in binary code. Besides a flight recorder, a plane also carries a cockpit voice recorder which records the conversation going on in the cockpit. In case of a crash, both the recorders prove to be very useful for analysing the cause of crash and helping designers to produce safer planes.

Caleb Williams is an American professional football quarterback who plays for the Chicago Bears of the National Football League.
