If a sample originally had 120 Adams of carbon 14 how many atoms will remain after 17,190 years

Biology

7 0

Answer:

15 atoms

Explanation:

About 15 atoms out of the 120 Adams would remain.

<em>Generally, the half-life of a substance is the time it takes for one-half of that substance to disintegrate.</em>

Carbon 14 has a half-life of approximately 5,730 years. 17,190 years means that the sample had stayed for 17,190/5,730 which is equal to 3 carbon-14 half-lives.

Out of 120 Adams,

  • <em>the first half-life will reduce 120 to 60 Adams</em>
  • <em>the second half-life will reduce 60 Adams to 30 Adams</em>
  • <em>the third half-life will reduce 30 Adams to 15 Adams.</em>

<em>Hence, at the end of the 17,190 years, approximately </em><em>15 Adams</em><em> would remain.</em>

Umnica [9.8K]

Rough endoplasmic reticulum, Golgi apparatus, cell membrane are structures that a protein that is destined to leave the cell would interact with on its journey from synthesis to exile from the cell of his birth.

The ribosomes, which are the molecules in charge of producing proteins, are what give the rough endoplasmic reticulum its name. A specific RNA fragment may instruct a ribosome to move to the rough endoplasmic reticulum and embed itself if it comes across there. The protein produced from this region will wind up inside the rough endoplasmic reticulum, where it will fold and be marked for transport to the Golgi apparatus through the process of glycosylation, which involves the addition of a tag molecule (often a carbohydrate).

Near the nucleus, the rough endoplasmic reticulum, which is continuous with the nuclear membrane, resembles a network of canals. Rough endoplasmic reticulum-produced proteins are either meant to form a membrane or to be released from the cell membrane. It would be much more difficult to discern between proteins that should exit the cell and proteins that should remain if there were no rough endoplasmic reticulum. As a result, the rough endoplasmic reticulum promotes cell specialization and increases organism complexity.

Colt1911 [192]

Answer:

Amygdalin

Explanation:

Amygdalin is a compound present in the apple seeds which contains sugar macromolecule and cyanide. When Amygdalin broken down by the action of enzymes, the sugar part is removed and only cyanide left which decomposes and produces poisonous gas of hydrogen cyanide. This is only be done if the animals crushed the apple seeds while eating apple.
