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:
centromere.
explanation:
the contromere is the structure that joins the two chromatids to make a chromosome.
The anterior and the posterior fontanelles is made up of the MESENCHYMAL CONNECTIVE TISSUES.
The anterior and the posterior fontanelles are two areas that are normally found on infant heads; at these areas, the skull bones did not cover the brain completely. The anterior fontanelles is located towards the front of the head while the posterior fontanelles is located at the back of the head. As the baby grow older, the mesenchmal tissues of the fontanelles turns into bone tissues.
