Answer:

Neurotransmitters are endogenous chemicals that are released by axon terminals of neurons into the synaptic junctions and act locally to control nerve cell functions.

•Imbalance of neurotransmitters such as serotonin,norepinephrine and dopamine have been linked with depression.

•Abnormal levels of neurotransmitter glutamate leads to changes in the level of Dopamine which can cause transition into psychosis.Dopamine has been implicated as possible cause of schizophrenia.

•Several transmitters are involved in analgesia system (pain suppression),especially involved are enkephalin and serotonin. When Serotonin are released and this causes local cord neurons ti secrete enkephalin,which is believed to cause both presynaptic and postsynaptic inhibition of pain fibres.

•Parkinson's disease also known as paralysis agitans results from widespread destruction of that portion of substantia nigra that sends dopamine-secreting nerve fibres to caudate nucleus and putamen this leads to decrease in dopamine.

•Acetylcholine is responsible brain arousal and muscle contraction.

Which area of biology states that living things undergo gradual, structural, and functional changes over long periods of time
Tasya [4]

Given what we know,  we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.

<h3>What we know about evolution. </h3>
  • This is a theory that was put forward by Charles Darwin.
  • Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
  • The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
  • These changes are hereditary.

Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.

Compare the physical and chemical properties of a compound to those of the elements of which it is composed
zepelin [54]

Answer:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water H_2O

2H_2O(l)\rightarrow 2H_2(g+O_2(g)

Physical property is defined as the property of a substance which becomes evident during physical changes. Water is liquid at room temperature whereas hydrogen and oxygen are gases at room temperature.

Chemical property is defined as the property of a substance which becomes evident during chemical changes. Water reacts with metals to form bases, hydrogen reacts with metals to form hydrides and oxygen reacts with metals to form oxides.
