Answer:
24555 years
Explanation:
Data provided in the question:
Half life of carbon 14 = 5700 years
carbon present in the dead man = 5% of the original amount of carbon 14
Now,
let the initial Amount of carbon be 'A'
Therefore,
after half life
Amount of carbon = 
Thus,
= 
here,
k is the decay constant
t is the time = 5700 years
therefore,
1 = 
or
0.5 = 
taking natural log both the sides
-0.69314 = 5700k
or
k = - 0.000122
therefore,
for dead man Amount of carbon = 5% of A = 0.05A
thus,
0.05A = 
or
0.05 = 
taking natural log both the sides
we get
-2.995 = - 0.000122 × t
or
t = 24555.18 ≈ 24555 years
In the treatment applied to dogs, in 22% of the dogs, the cell specialization process was not successful because the stem cells did not improve the arthritis problem
Stem cells are a type of cell that can transform into any of the 44 types of cells in the body, in a process called cell specialization. For instance:
- Neurons
- Sperms or ovules
- Pneumocytes
- Cells of the epidermis
Cell specialization is a term that refers to the process in which stem cells change from one cell type to another, stem cells modify their genetic expression, acquire specific morphology and functions.
According to the above, the treatment process that was not successful in 22% of the dogs was the cell specialization process, so they could not become the type of cell required to improve the condition of the dogs.

D.) Strong nuclear force is most like electric because they are both related to distance
1. Species vary over time
2. The fossil and the living species will have some similarities and some differences
<h2>
Answer:</h2>
Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h2>
Explanation:</h2>
Mutation assumes a significant job in evolution. A definitive wellspring of all hereditary variety is a mutation. It is significant as the initial step of development since it makes another DNA succession for specific quality, making another allele.
Recombination additionally can make another DNA succession (another allele) for a particular quality through intragenic recombination. Mutation going about as a developmental power independent from anyone else can possibly cause huge changes in allele frequencies over exceptionally significant stretches of time.
