The process of protein synthesis involves two steps such as transcription and translation. In the process of transcription the encoded information in the DNA is transcripts or encoded into messenger RNA or mRNA inside the nucleus. This mRNA then comes out of the nucleus to the cytoplasm. In the process of translation the mRNA molecule attach with the ribosomes and tRNA molecules to synthesise the protein.
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
There's the cumulus, the stratus, cirrus, and nimbus.
Hello! My name is Zalgo and I am here to help you out on this amazing day. Organisms grow, but only certain organisms are capable of growing. The meaning of growing is "to get bigger/expand" and the way that multicellular cells grow is by making more cells. Plants also have special tissues called "Meristems" where the growing process happens. Single celled organisms (unicellular organisms) increase their numbers by "dividing" and making more cells like themselves.
I hope that this helps! :3

The right answer is the first phase of the general adaption syndrome.
The concept of stress was introduced by Hans Selye. He describes the mechanism of the adaptation syndrome, that is to say all the modifications that allow an organism to bear the consequences of a natural or operative trauma.
In fact, it is the double-perception of a state of divergence between a demand for adaptation at a given moment and the ability to cope with it. It is an energy expenditure. It can be positive or negative.
The stress syndrome evolves in three successive stages:
*"Alarm reaction": the defense forces are mobilized
*"Resistance stage": adaptation to the stressor
*"Stage of exhaustion": inexorably reached if the stressor is sufficiently powerful and acts a long time.
