Answer:
The solution of P. aeruginosa will yield higher Tm value.
Explanation:
The solution of P.aeruginosa contain 68% G+C composition as a result the DNA of P.aeruginosa is more stable than the DNA of mammal contain only 42% G+C composition.G+C composition is most stable because guanine is linked to cytosine by 3 hydrogen bonds whereas adenine linked to thymine by 2 hydrogen bonds.
As P.aeruginosa DNA is more stable than mammalian DNA,as a result the DNA solution of P.aeruginosa will yield high Tm(melting temperature) value than that of mammalian DNA.
To show he presence of a trait you would need to follow it through multiple generations in a pedigree.
Answer:
In igneous rocks, the texture is determined by their cooling rate.
Explanation:
Answer:
Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.
Explanation:
Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.
The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.
Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.
Answer:
This is because the voltage gated sodium channels which opens for the influx of sodium ions, which caused increased postivity of the axoplasm closed, with simultaneous opening of potassium channels.
Therefore depolarization stopped, thus propagation and transmission of action potential (caused by depolarization) which cause the reversal of charges in the membrane (making the axoplasm more negative) for the voltage rise to 40mV also stopped.
In addition the simultaneous opening of voltage gated potassium channels caused K+ to leave the axoplasm to the external environments. This makes the inner membrane to be negative further lowering the potential, to -75mv. This is re-polarization.
