If you are asking about the myths of the Bermuda Triangle, which involve a portal to another universe or flying saucers, then the answer is: that has been disproven.

While, allegedly, ships and planes disappear on clear days and without a trace, neither statement is true. Most disappearances happen in bad weather; and the disappeared ships and places have been found on the bottom of the sea.

It is possible that a phenomenon known as “blue holes” may explain some of the ships disappearing. Blue holes are submarine limestone caves of incredible depth. There is reason to believe that blue holes can engender whirlpools, which could account for ships disappearing.

It has been suggested that a freak magnetic phenomenon can account for the planes going down. That has not been proven.

But the most likely explanations involve bad weather, and possibly blue holes. All of which are natural and terrestrial phenomena. There is no reason to assume the supernatural or the extraterrestrial.

So: yes, it exists. No, there’s nothing special or supernatural about it.

And ships and planes routinely sail and fly over the Bermuda Triangle. Most of them reach their destination

Christmas is a termination event of a 12-day long festival. Many people don’t know the preceding events and only focus on the main festival. The 12 days of Christmas are all about fasting and penance to commemorate the suffering faced by Jesus.

The last day of the 12-day series is known as Christmas and is celebrated on December 25 every year. It falls on the winter solstice day in the Roman calendar and is the darkest day of the year. The birth of Jesus comes as a ray of hope and marks the beginning of a journey towards enlightenment. Christmas is all about decorating Christmas trees, eating with families and friends, and having lots of fun. The core values of sharing are instilled in children from the beginning, and they learn to have a deep sense of moral values.

Christmas shouldn’t be used only to have fun. It is the time when we should think about the plight of those people who are less fortunate than us. It is the time when charity works are organized all across the globe, and the revenues generated from them are used for the betterment of the poor and the needy. People use this time to reconnect with their family and friends over a delicious dinner; they play games and give them gifts. This fosters the familial ties between people and makes them happier and joyful.

Tin is less reactive than zinc. It is less likely to dissolve in the liquid stored in the food cans. Tin reacts only with powerful acids whereas zinc can easily react even with tomatoes, so it is not safe to store food in zinc-plated cans.

The primary function of respiration is to provide energy to the living things. Living things obtain oxygen by respiration, which is used for the oxidation of food to release energy. This energy is used by living things to perform all functions.

Precipitation reaction is a chemical reaction occurring in an aqueous solution where two ionic bonds combine, resulting in the formation of an insoluble salt which are called precipitates.

Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. A precipitate is a solid that forms out of solution.

Example:

The precipitate Silver Chloride is formed when Aqueous silver nitrate (AgNO3) is added to a solution containing potassium chloride (KCl) .

AgNO₃(aqueous) + KCl(aqueous) —–AgCl(precipitate) + KNO₃(aqueous)

The food has stored energy, which is released during respiration. Therefore, all living organisms respire to get energy from food by breathing the air. During heavy exercise, fast running, cycling, walking for many hours or heavy weight lifting, the demand for energy is high.
