Answer:
Hyperpolarization
Explanation:
At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).
It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.
Answer: Option A) Oxygen may not have been able to accumulate in the atmosphere
Explanation:
Ozone, O3, is an allotrope of oxygen having three atoms in the molecule instead of the usual two present in molecular oxygen. Ozone is generated from oxygen, and is the only form in which oxygen can exist in the atmosphere.
Answer:
aquatic plants are water lily
Answer:The respiratory system helps create sound that enables humans to communicate with each another.
Explanation:
Answer:
c.reflects evolutionary history.
Explanation:
The best classification system in biology is that that reflects evolutionary history, this is because more developed animals evolved from ancestors, this means that little modifications on the DNA happened over the course of million of years that created the animals that we know today, so this little differences would be relfected on a classification system.
