1. 20% of Earth’s oxygen is produced by the Amazon rainforest?
20% of Earth’s oxygen is produced by the Amazon rainforest
Our atmosphere is created from roughly seventy-eight percent nitrogen and twenty-one percent oxygen, with varied different gases present in little amounts. The vast majority of living organisms on Earth need oxygen to survive, changing it into CO2 as they breathe. Thankfully, plants frequently replenish our planet’s oxygen levels through photosynthesis. throughout this method, CO2 and water are converted into energy, releasing oxygen as a by-product. Covering 5.5 million sq. kilometers (2.1 million sq. miles), the Amazon rainforest cycles a major proportion of the Earth’s oxygen, absorbing massive quantities of CO2 at a similar time.
2. Men are more likely to be colorblind than women?
Men are more likely to be colorblind than women
The genes responsible for the most common kind of colorblindness are found on the X chromosome. even though girls have the genes on one of their 2 X chromosomes, a properly functioning gene on the other one makes up for that loss. If men inherit the gene on their only X chromosome, they’ll become colorblind.
3. Some metals are so reactive that they explode on contact with water?
Some metals are so reactive that they explode on contact with water
There are certain metals – including potassium, sodium, lithium, rubidium, and cesium – that are therefore reactive that they oxidize instantly once exposed to air. they will even produce explosions once dropped in water! All elements strive to be chemically stable – in different words, to have a full outer electron shell. to achieve this, metals tend to shed electrons. The alkali metals have only 1 electron on their outer shell, creating them ultra-keen to pass on this unwanted passenger to another element via bonding. As a result, they form compounds with different elements therefore readily that they don’t exist independently in nature.
4. The Eiffel Tower can be 15 cm taller during the summer?
The Eiffel Tower can be 15 cm taller during the summer
When a substance is heated up, its particles move more and it takes up a bigger volume – this can be called thermal expansion. Conversely, a drop in temperature causes it to contract once more. The mercury level inside a thermometer, for example, rises and falls because the mercury’s volume changes with the ambient temperature. This effect is most dramatic in gases, however, happens in liquids and solids like iron too. For this reason, Big structures like bridges are built with expansion joints which permit them some leeway to expand and contract without causing any damage.
5. About half of your body is bacteria?
About half of your body is bacteria
That’s right. A 2014 study estimates that the human body consists of thirty-nine trillion bacteria and thirty trillion human cells. within the past, researchers thought we were additional bacteria than human with a ratio of 10:1. whereas this new calculation is maybe nearer to the true numbers, it’s not a tough fact.
