The right answer is <span>Refractory period.
At the moment when the action potential is emitted, the fiber being depolarized, it is impossible to depolarize it again. It is, therefore, necessary to wait until the membrane potential returns to a value below the critical threshold in order to be able to excite it again. We are thus led to distinguish two periods that characterize its excitability.
An absolute refractory period: during which any stimulation, even supraliminal, is ineffective since the fiber is already depolarized.
A relative refractory period: during which a second action potential can be omitted provided that the depolarization produced by the excitation reaches the critical threshold, which implies that it is more important since the value of the resting potential has not been restored yet.</span>
The process for connecting two monomers together is called dehydration synthesis. Dehydration means
“removal of water” and synthesis means “to join together”. So in this
process, two monomers are covalently bonded by the removal of a
water molecule. Each organic monomer has a hydroxyl group on
one side and a hydrogen on the other. When two monomers line
up side by side, they will have these two functional groups facing one
another. The H and the OH will break off of their respective
monomers and bond forming a water molecule. This is the dehydration
part of the process. Each monomer now has a carbon atom that needs
to covalently bond with something, so they bind to each other forming
a polymer. That is the synthesis part of the process.
The cause of mutations in gene expressions are the changes of gene instructions that causes your protein to malfunction. The effect of mutations are the genes not being able to function properly and send the wrong codes/info to your cells.
Answer:
glycolysis
Explanation:
In the process of glycolysis only 2 molecules of ATP are produced. Maximum energy is released, when the reduced coenzymes produced in the process of Krebs cycle are oxidised in the process of oxidative phosphorylation in electron transport chain.
The excessive use of water for irrigation in dry climates, with heavy soils, causes salt accumulation because they are not washed out by rainfall. The practice of waterlogging without adequate drainage has also become a serious cause of soil salinization .
