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.

For how long can muscles rely soley on lactic acid fermentation to generate ATP
ASHA 777 [7]
For most activities it usually lasts at least 90 seconds in duration for you to solely rely with lactic acid. <span>The ultimate energy fuel is adenosine triphosphate (ATP), which is produced in the cell. Lactic acid in the cell will itself metabolize into ATP, a process by which energy can be produced without oxygen, known as the anaerobic lactic energy system. </span>

Answer:

Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!

Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.

Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.

The right answers are:

create two identical cells ==> mitosis

create four non-identical cells ==> meiosis

create haploid cells ==> meiosis

creates diploid cells ==> mitosis

occurs in all cels other tha gametes ==> mitosis

occurs in all cells related to sexual reproduction ==> meiosis
