I assume the answer is growth or maybe excretion. To be honest, I'm not quite sure which one is the correct the answer.
I hope it gave you a hint, at least, of what the answer going to be.
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>
Answer;
-Spinal cord may be affected
Explanation;
-If the caudal portion of the Neural tube failed to develop properly, the spinal cord may be affected.
-The neural tube is the embryonic structure that develops into the brain and spinal cord.
-Its defects arise from failure of embryonic neural tube closure by the fourth week of pregnancy, causing malformations of the brain and spine.
