How did scientists determine SM0313 is the oldest star ever discovered?

Biology

levacccp [35]3 years ago

i think it has to do with how old it looks, because a star starts off as a baby little star, a different color and size. its also in a nursery with a lot of other stars, which is called a nebula. as the stars grow older and larger, they change color and drift apart. the scientists must've seen that the star has a totally different color from the baby ones, way brighter and much larger, also seeing that stars grow apart, it has not really many stars living around it for miles and miles. they must've guessed that it was probably really old.

REALLY NEED HELP WITH HOMEWORK! VERY URGENT!!!! DUE IN AN HOUR!! Do you think all the cells in an animal are exactly alike? Why
Marianna [84]

Answer:

No I do not think that all of the cells in an animal are the same. All of the cells complete different things. For example, Mitochondria cells break down sugars and other compounds into celluar energy, while the skin cells are busy producing Keratin. This shows that no two cells are exactly the same.

Hope this helps!

Generally, glycogen is a main source of energy for the body
