Answer:

This is the site of gaseous exchange

Explanation:

Gaseous exchange is the mechanism by which oxygen is substituted for CO₂ in the body. CO₂ laden blood is carried to the alveoli, which is wrapped with numerous capillary beds and with walls that are thin. When a person inhales, the difference in the partial pressure of the various gases ( oxygen and carbon dioxide) causes them t move down their concentration gradients, with CO₂ diffusion into the lungs from red blood cells, and oxygen binding to the haemoglobin in the red blood cells, after which they are carried to all body tissues for cellular respiration. During exhalation, the CO₂ in the lungs is expelled to the exterior and the process repeats.

If the extracellular fluid has an excess of sodium ions, a. sodium ions move into cells b. intracellular fluid moves to the outs
Mandarinka [93]

Answer:

b. intracellular fluid moves to the outside of cells

Explanation:

The presence of an excess of sodium ions in the extracellular fluid would make it hypertonic with respect to the intracellular fluid. The concentration gradient would drive the intracellular fluid towards the outside of the cell to balance the concentration of the fluids on either side. The passive movement of fluids occurs across the cells and is driven by the concentration gradient only. The biological membranes are permeable for fluid movement such as the movement of water across it.

1) Glycogen phosphorylase catalyzes the removal of glucose from glycogen. The ∆G°’ for this reaction is 3.1 kJ/mole 1. Calculate
Andru [333]

Answer:

1. G° = -RT ln (G1P/P)

3.1 = 8.314 × 310 × ln (G1P/P)

3.1 / 2577.34 = ln (G1P/P)

0.0012 = ln (G1P/P)

0.0012 = (log G1P/P)/log 2.71828

0.4342 × 0.0012 = log G1P/P

0.00052 = log G1P/P

G1P/P = 10^0.00052 = 1.0012

P/G1P = 1/1.0012 = 0.9988

2. The cleavage of glycogen phosphorolytically is beneficial for the cell to conduct the process as the discharged glucose is phosphorylated. A general hydrolytic cleavage would give rise to only a glucose, which has to be phosphorylated again with the help of ATP.  

Another merit of phosphorylated glucose is that it comprises the negative charge and cannot diffuse out of the muscle cell. Thus, the reaction will not be at equilibrium under the physiological conditions and always encourages the generation of the products. The formation of products will amend the change in free energy in such a manner that the reaction will always carry in the forward direction.  

3. Greater the ratio of [Pi]/[glucose-1-phosphate], higher will be the relative rate of glycogen phosphorylase in comparison to the phosphoglucomutase as the transformation of Glu-1-P becomes slow because of lesser accessibility of substrate.

After having read, how do you think pollution in one sphere can have an impact on another? Be specific and explain.
Orlov [11]

Answer:

Pollution can impact other spheres

Explanation:

Okay here ya go :)

As more and more pollution occurs it can cause the ozone layer to slowly start to decay in a way as the sphere get thinner. What this impacts is the troposphere. Since the ozone layer starts to fade away it can't filter out as much harsh rays from the sun. Those rays eventually get to the earth's surface and bounces off the surface warming up the earth causing life to be affected in the troposphere by warming up the earth.
