<span>Appositional growth refers to process of bone growth by which chondroblasts add new layers of cartilage to existing layers of cartilage. By this process, the cartilage is added under the hard covering called the periosteum, which results in the growth of diameter or thickness of bone and not length.</span>
DNA replication must be completed before meiosis, doubling and already diploid genome. Meiosis will then distribute a haploid<span> genome into each of four gametes provided nothing goes wrong.</span>
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
The Hershey–Chase experiment was based on a bacteriophage T2 (a virus), to that DNA is the genetic material. Bacteriophage T2 attacks bacterium and makes its copies. Based on the experiment, Hershey and Chase deduced that it is the DNA of virus enters bacteria to make virus copies. To trace viral DNA, Hershey and Chase label DNA with ³²P (radioisotope of phosphorus) because phosphorus is not present in most of the proteins.
