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

Biology

adelina 88 [10]3 years ago
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>

Explain how and why different parts of a plant are sinks for the translocation of sucrose at different times of the year in a co
rusak2 [61]

Answer:

The sucrose is transported around the plant in phloem vessels. It needs to be able to reach all cells in the plant so that the sucrose can be converted back into glucose for respiration. The movement of sucrose and other substances like amino acids around a plant is called translocation .

Belowground organs of plants (e.g. roots and rhizomes) are sinks during plant growth since they cannot perform photosynthesis. Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing

A pod of bottlenose dolphins is showing signs of stress in the Gulf of Mexico. Why would it be important for scientists to study
anyanavicka [17]
<span>Age structure would help scientists determine if the problem exists with young or old dolphins.

The age structure shows the distribution of the ages of the individuals in a population. This not only shows the type of change taking place in the population (increasing, decreasing or staying the same) but also is able to help us relate problems to ages. By determining the which age group is more stressed, the scientists will be able to narrow down the causes of the stress and create more accurate hypotheses.
