A corpse with flesh intact, found in the Alps in 1991, was dated by the carbon-14 method and showed a parent-daughter isotope ra

tio of approximately 1:1, with slightly more parent material than daughter material. The half-life of carbon-14 is 5,730 years. Which of the following statements is TRUE?
A. Since the body was still organic and had not been petrified, it was inappropriate to use the carbon-14 process.
B. The age could logically be 6,730 years.
C. The age could logically be 5,300 years.
D. The age could logically be 6,000 years.

Answer:

C. The age could logically be 5,300 years.

Explanation:

"One half-life after a radioactive isotope is incorporated into a rock there will be only half of the original radioactive parent atoms remaining and an equal number of daughter atoms will have been produced." The ratio of parent to daughter after one half-life will be 1:1. After two half-lives, half of the remaining half will decay, leaving one-quarter of the original radioactive parent atoms. Those transformed atoms bring the tally of daughter atoms to three-quarters of the crop of parent plus daughter atoms. The ratio of parent to daughter atoms after two half-lives is therefore 1:3 (one-quarter to three-quarters)".

A ratio 1:1 leads to 5300 years, the closest option to half-life to the carbon-14.

What happens to an animal cell that is placed in a hypotonic solution
ipn [44]

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Please help me! <br> how can invasive species change an ecosystem?
nlexa [21]

Answer:

by introducing an invasive species it can drastically change the ecosystem. let's say you have the manatee, it has no natural predators, if you add an invasive species that eats manatees it may cause other things to start eating them too. this would cause the population to dwindle until there are few to none left because the invasive species population will go unchecked because nothing is accustom to eating them
