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: A PEDIGREE is a family-tree like representation of how organisms are related based on ANCESTRY. It shows genetic relatedness or blood relationship between individuals or organisms.
Explanation: Pedigree can be used to determine
1. Family history or genealogy.
2. Genetic or blood relationship.
3. Coefficient of relationship.
4. Degree of relationship.
5. Proportions of shared genes.
6. Mode of transmission of diseases.
7. Risk evaluation or determination.
Genetic counseling.
8. Linkage analysis.
Pedigree symbols are used in constructing pedigree.
Answer: -plants
-animal waste
Explanation:
Fossil fuels are the fuels which are generated after a long time taking geological process over the buried organic matter obtain from dead animals, animal dung and plants. The organic matter remain under the heap of earth crust under intense heat and pressure. The heat and pressure generate fuels which are valuable for the entire society as when they are burned they produce huge amount of thermal energy. These includes the crude oil like petroleum, natural gas and coal.
A. is the answer, the closer the peaks are to eachother, the higher the frequency and energy.
Answer:
D: There is no wind on the moon
