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:
Antibodies develop to fight off the virus.

L-cysteine and L-valine
Penicillin is a secondary metabolite commonly found in the filamentous
fungi and they are synthesized from the amino acid precursors L-cysteine, L-valine and l-α-aminoadipic
acid. β-lactam antibiotic penicillin are antibiotics commonly used for the
treatment or therapy of infectious diseases.
