Charles Darwin studied the the beak structure of finches native to the Galapogos Islands. The study of these finches enabled Darwin to study and publish his theory of evolution by natural selection. Darwin realized the importance of the finches after leaving the islands while he was studying specimens he brought back with him. The trait he noticed was the differences in the size and shape of the finches beaks. He theorised that new species will arise when some factor causes a population to be divided.

Choose the law that BEST explains the example:
german

Answer:

3rd law

Explanation:

First law of Newtons :

 Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.  

The second law of Newtons :

The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.

The change in the linear momentum of the object is equal to the force.

Third law of Newtons :

This law states that every action has its reaction with the same magnitude but in the opposite direction.

When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.

Therefore the answer is "third law".

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.
