Nuclei of atoms that make up the newborn baby were made in :?

Question

A - in the mother's body. B - ancient stars. C - the food the mother eats before giving birth. C - the Earth

Answer 1

Supernova:

from wikipedia:

Supernova nucleosynthesis refers to the production of new chemical elements inside supernovae. It occurs primarily due to a neutron capture process known as the r process. However, there are other processes thought to be responsible for some of the element generation, notably a proton capture process known as the rp process and a photodisintegration process known as the gamma (or p) process

for more detail see the link below.

Answer 2

B is more or less the answer, at least for the heavier elements (anything above helium). The requirements for the production of larger elements requires move energy that what a typical star generates in nuclear fusion. This occurs whenever a star begins to collapse and the temperature of the star becomes so hot that heavier elements are formed from fusion. They are released when the star achieves a critical mass and explodes in the form of a supernova.

The earth and its solar system are in a second generation, being comprised by the remnants of an ancient supernova. Heavier elements coalesced into orbiting matter, e.g. planets and asteroids. That is why we see the larger elements, which are constantly being recycled through various means, including human reproduction. Indeed, we are truly the children of the stars.

Answer 3

B - ancient stars is closest to correct. The hydrogen is abundant in stars and is the fuel for the fusion reaction that powers stars. This fusion within stars can form the lighter elements, up to somewhere around iron. Formation of heavier elements takes more energy, so the supernova nucleosynthesis process mentioned earlier is probably the source of most of them. Finally, fission of heavier elements into lighter ones by radioactive decay is the dominant (perhaps the only) way an atom changes from one element into another on a planet. Outside the high-energy environment of a star or supernova, the changing of an atom from one element into another (by changing the number of protons in the nucleus) is rare.

Answer 4

B- ancient stars
Heavy elements are born by nuclear fusion within stars.
Some of those elements formed into the earth when our solor system was formed.
Since the beginning of the earth, those elements have passed through different complex forms, at one time being plants, at others being animals.
At one point the mother absorbed those elements, either from her mother, or through digestion, and passed them on to the newborn.

Answer 5

B- ancient stars. this is for the majority.

although it is possible that some of the nuclei have changed since then and given that C A and D all happen after that event then it is concievable that some of these nuclei have been created in the described procesees

Answer 6

B - Those of us that are true scientists (or science lovers) got this one quick. Yes we were all once part of a star before it blew up. (So was the computer you are sitting at.) Even if our atoms never again become part of another super nova (Our sun isn't big enough) ...it's nice to know that the sub atomic particles which make up each of us, will still be spinning on their axis, billions of years from now. Matter and energy can never be destroyed. We have each already been in existence for 13.7 billions years so far. (Since the Big Bang.) Welcome to immortality.

Answer 7

B - ancient stars is correct, for all elements except hydrogen, which dates from the Big Bang. None of the other proposed answers is correct.

Answer 8

B - the relevant part is atomic nuclei. It doesn't matter where they are, the nuclei of atoms are made in stars (hey that kind of rhymes).

Answer 9

A - in the mother's body

Answer 10

b-ancient stars. unless the mother can create fusion through mating.
