Answer:
t= 3886.18 years old
Explanation:
Whenever an animal dies de C14 and N14 begin to disintegrate in such a way that the proportion between C14 and C12 decreases, with a semi-disintegration period of 5.730 years, T. To get to know how long it takes an element to disintegrate, we must use this semi-disintegration period, which is the time it takes until the amount of the element is reduced to its half.
We can find the age of the fossil, t, by using the next formula:
t = - (T x ln (C14))/ ln (2)
t = - (5730 x ln (0.625)/0.693
t= - (-2693.12)/0.693
t= 3886.18
Answer:
Fur color that closely matches the eucalyptus bark color
Explanation:
In terms of evolving from land dwellers to tree dwellers, the number of offspring does not matter. Although the ability to run faster is a good evolution for escaping predators, it does not help the koalas evolve to be better tree dwellers (how would you run using only the trees?). Communicating with their peers would be convenient for survival, but it does not help koalas become better tree dwellers. What does help koalas survive better by traveling through the trees is camouflaging with the bark of the tree to hide from predators.
The generalization that all organisms are composed of cells was established through multiple observations in various kinds of animals and plants. A controlled experiment of finding cells in all the kinds of living organisms is not possible or is infeasible as it will require prior knowledge of all the kinds of organisms inhabiting Earth and the effort to catch and bring them in the controlled environment of the lab for testing.
