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:
To provide quick energy to the muscles.
Explanation:
It is advantageous for oxidative muscle fibers to have smaller diameters compared to glycolytic muscle fibers because these fibers depend on aerobic respiration to provide energy to muscle contractions. This smaller diameter enables the oxidative muscle fiber to move very quickly in order to provide quick energy to the muscles. If their diameters are big so they are unable to provide quick energy in the form of ATP to the muscles for their contractions.
1. The ATP molecule can store energy while attaching ADP to the terminal phosphate group. The energy is released when the phosphate group from the ATP is broken down and inorganic phosphate is released.
2. Anabolic pathway involves the use of ATP to synthesize large molecules. However, catabolic pathway involves the breaking down of larger molecules and release energy. Therefore, Photosynthesis is the anabolic pathway and respiration is the catabolic pathway.
3. An ATP molecule when hydrolyzed releases 7.5 KCal of energy.
4. Both chemosynthesis and photosynthesis are the processes of producing food. However, photosynthesis requires sunlight as the source of energy and chemosynthesis requires chemical energy.
5. The chemical equation for photosynthesis is 6CO₂ + 6H₂O + energy - C₆H₁₂O₆ + 6O₂
Answer:
Stomach - break down food
Small intestines - absorb all nutrients and seperate them from waste
Large Intestines - continue collecting any remaining nutrients and expell any waste
