Out of the choices given, the most important in determine the plant and animal population that can exist in an area is the temperature. Both plants and animals need a certain temperature to survive in certain areas. The correct answer is D, temperature.
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
Answer:
The answer is The Prefrontal Cortex
Explanation:
The Prefrontal Cortex is a part of The Frontal Cortex at the front of the brain and accounts for more than 10% of our brains. It controlls key functions which involve making decisions and plans, setting long term goals and self control. To see the effects in an example, you can search for the case of Phineas Gage.
