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

Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.

MrRissso [65]

Answer:

c. have changed the behavior of elk.

Explanation:

Wolves were reintroduced into Yellowstone Park in 1995. Prior to this time, they were a major predator in the park. Their reintroduction after a decade resulted in a change in the behavior of the Elk which now had a large population in the park and appeared in large herds.

The Elk's behavior has also changed as they do not move into farther thickets so as not to be attacked by wolves. Also, they no longer move to open fields where they grazed as herds to avoid being preyed upon by lions. Vegetation is now restored due to this change in behavior of the Elk.
