Answer:
It can enhance survival because the animals for example birds are migrating to those places for high or increasing resources
Explanation:
Answer:
c) that the formation and decomposition of ES is the same for a period of time
Explanation:
Michaelis-Menten equation :
This model explain the approach to enzyme kinetics.The Equation shows how a Free enzyme E and Product P is formed depicting by Following equation.
E+S⇌ES→E+P
Left side represents
E =enzyme
S=substrate
ES=enzyme-substrate complex
Right side
E= Free enzyme
P= product
c) that the formation and decomposition of ES is the same for a period of time
Answer:
6.82 kg
Explanation:
Given that the amount of water is 15L and we know that the density of water is ≈ 1kg/L. The mass of water is given by mass = volume x density, i.e,
mass = 15 x 1 = 15 kg. Also the specific heat capacity of water is 4.186 KJ/kg.
The sublimation enthalpy of dry ice is 571 KJ/kg.
Now, the amount of heat lost by water is entirely used up for the sublimation (conversion from soild to gas) of dry ice. And the heat (Q) lost by water is given as : Q = mCΔT, where m is the mass of water, C the specific heat capacity of water and ΔT the change in temperature.
Here, Q = 15 x 4.186 x (90 - 28) = 3892.98 KJ.
This amount of heat is taken up by the dry ice for its sublimation. Also the energy taken by dry ice (Q') for its sublimation is given by: Q' = m'L', where m' is the mass of dry ice, L' is the latent heat of sublimation (i.e, the amount of heat required per kg of a substance to sublime) of dry ice amd L' = 571 KJ/kg.
Now, Q' =m'L' = heat lost by water = 3892.98KJ.
And, m'L' = m' x 571 KJ/kg = 3892.98 KJ. (Dividing with 571)
Therefore, m' = 6.82 kg.
