It doesn't have a galactic value for Ca, but the solar system estimates are fairly close to the average expected values for stellar systems that are around the same age as the Sun. Younger systems will generally have slightly higher proportions of everything heavier than hydrogen. | |

| Jan 5, 2022 at 9:50 | comment | added | dnatech | I am going by an adage, "Where's there is smoke, there is fire." As my moniker indicates, I have done work in the biological sciences, and as such the reason I am making this question is that calcium is more than just a vital mineral for biological systems...it is involved with channeling ions through cell membranes, signalling for protein replication, signaling for hunger, signaling for sex drive, pulsed release for trauma, staged reproduction in mitosis, and more. I would say every living organism on Earth utilizes calcium in important functions. | |

| Jan 4, 2022 at 22:31 | comment | added | uhoh | Hi @dnatech I've cast the fifth and final close vote. Don't worry, questions can be reopened after they are improved. If you look around this Stack Exchange site (or any of the almost 200 other SE sites) you'll see that questions are generally asked in a well-developed state. While sites like Quora have single sentence questions, here it's generally necessary to include some explanation of the question and what the answer should include, and ideally some evidence of research. | |

| Jan 3, 2022 at 11:15 | comment | added | dnatech | I'm trying to say something to the effect that are there stars richer in calcium as compared to other stars...is our sun, for example, richer in calcium as compared to most other stars... | |

| Jan 3, 2022 at 0:11 | comment | added | uhoh | I don't understand the drive-by pile-on down-voting on a new user's first question. It's unnecessary, unhelpful and very unwelcoming. Give the OP time to improve their question! You want how to ask a good SE question to be what new users learn first, not "this site is unwelcoming"! | |
