Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years
The half-life of carbon-14 is 5730 years.
In this manner, after
1 half-life there is 50 % = 1/2 of the first amount left.
2 half-lives there is 25 % = 1/4 of the first amount left.
25% is two half-lives.
Every 50% of life requires 5730 years.
So two half-lives require 2 × 5730

Answer:
Forests. Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis
Explanation:
Plants are involved in the Carbon Cycle by absorbing Carbon out of the atmosphere in order to photosynthesize. The Carbon is used during the photosynthesis. It gets back in the environment by a plant's breathing process.
Answer:
if there was no photosynthesis, then we won't have plants. Plants will die out, and we will not get the oxygen needed to survive.
Answer:
The process of reuptake occurs when the sending neuron normally reabsorbs excess neurotransmitter molecules.
Explanation:
The process of reuptake takes place when a cell that initially produced and emitted a particular substance reabsorbs it again. Serotonin is one of the secretions affected by this process since it can be reabsorbed if it sticks to receptors located in the original nerve where it was produced to be then released once again.
