Answer:
C
Explanation:
Homologous structures compare the same anatomical features in different species. C is correct because it compares the same trait (wings) in different species (dragonfly vs. bat)
Answer:
The liver cell with ∆G'° = -2.34 kJ/mol
Note: The question is incomplete. The complete question is given below:
The following data represents cellular concentrations of ATP, ADP, and inorganic phosphate from various mammalian organs. Calculate the actual Gibbs free energy change for hydrolysis of ATP under physiological conditions (assume 37°C). Assume ATP hydrolysis has a standard free energy change of -30.5 kJ/mol. Which cell type yields the greatest free energy change for ATP hydrolysis? Show your work. ATP (MM) ADP (mm) Pi. (mm) Liver 3.5 1.8 5.0 Muscle 8.0 0.9 8.0 Brain 2.6 0.7 2.7 mM=millimolar, ATP=adenosine triphosphate, ADP-adenosine diphosphate, Pi=inorganic phosphate
Explanation:
The equation for ATP hydrolysis is as follows: ATP ---> ADP + Pi
Standard free energy change, ∆G'° = -RTlnK'eq;
where K'eq is equilibrium constant; R = 8.315 J/mol.K; T = 298 K
K'eq = {[ADP][Pi]}/[ATP]
For Liver:
∆G'° = -(8.315)(298) × ln (1.8 × 5.0/3.5)
∆G'° = -2.34 kJ/mol
For Muscle
∆G'° = -(8.315)(298) × ln (0.9 × 8.0/8.0)
∆G'° = 0.261 kJ/mol
For Brain
∆G'° = -(8.315)(298) × ln (0.7 × 2.7/2.6)
∆G'° = 0.79 kJ/mol
Answer:
X
Explanation:
The mother passed on the gene, the father passed on the X chromosome and their son now has it.
The correct answer is - A strong wind blows across a Midwestern prairies.
An energy flow through a natural system is when we have no human interference or any man made objects in the process. A strong wind that blows across a Midwestern prairie is a nice example of this. We have a natural unmodified by humans environment through which a natural phenomenon is bringing energy flow. The energy flow will of course operate in different manner and have different effects compared to the ways in which the humans would have used it. The strong wind in the prairie will bring in lot of small particles, sediments, with its energy and deposit big portion of them in the prairie, thus making it more fertile.
