The anther is a kind of tissue-covered pouch that… Continue reading Where Do the Pollen Grains of Flowering Plants Develop?
The sun itself is a huge nuclear mechanism. It releases every day an amount of energy equal to that of millions of atomic bombs. A nuclear bomb will not leave the slightest trace on the sun and will not alter its activity. Moreover, since the solar atmosphere has a temperature of thousands of degrees, the… Continue reading What If We Shot a Nuclear Bomb Into the Sun?
We will start by explaining the physical phenomenon on which the temperature that something can have depends. When the particles of an object move a lot, they generate heat, and the entity has a higher temperature. When particles move less, there is less heat, and the thing is colder. We can imagine a point where… Continue reading Highest and Lowest Temperature in the Universe?
