No. Yes phenotypes are important for example those with longer legs can run faster and hence escape predators
But genes also code for unseen proteins
For example, if a disease is introduced those with long legs won't survive but those who have the genes which code for the complimentary antibody have the ability to kill the pathogen and hence survive.
Answer:there are many
Explanation: adhesion, surface tension, heat of evaportation
Autotrophs get energy from photosynthesis.
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!!
