If the 14C level of fossils is 73% compared to living organisms. It will be 2602 years.
<h3>What is radiocarbon dating? </h3>
This method is used to estimate the relative age of carbon-based materials. This is done usually for fossils which originate from living organisms.
This age is estimated by estimating the percentage of carbon-14 isotopes in the fossil. This is done by comparing this percentage to a reference standard used internationally. This method is of tremendous use in palaeontology. It has also found its use in hydrology, oceanography, geology etc.
Fossil age is determined by
At = (Ao) x (1 - 0.5)^(t/h)
Here, At/Ao = 0.73
So, 0.73 = 0.5^(t/5730)
Therefore, t = 2602 years

Yes A is the correct answer
Eurythermic: (of an organism) able to tolerate a wide range of temperatures.
Stenothermic: <span>A </span>stenothermic<span> is a species or living organism only capable of living or surviving within a narrow temperature range.
</span> Euryhaline<span>: (of an aquatic organism) able to tolerate a wide range of salinity.
</span>Stenohaline: <span>(of an aquatic organism) able to tolerate only a narrow range of salinity.

Answer:
haploid
Explanation:
Sexual reproduction involves the production of haploid gametes by meiosis, followed by fertilization and the formation of a diploid zygote.
Long eyelashes is the dominant trait because, in the last sentence, donna mentioned how nearly everyone in the family had long eyelashes, while barbara and her had short ones. this proves that long eyelashes are much more common in the family than short eyelashes, which means long eyelashes would be dominant, while short eyelashes would be recessive.
