Humans ferment lactic acid in muscles where oxygen becomes depleted, which is why sometimes if you finish a run and don't stretch soon you have have discomfort. <span />
Answer:
The correct answer is option C (voltage gated Na+ channels).
Explanation:
Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.
The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.
At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.
Thus, option C (voltage-gated Na+ channels) is the correct answer.
Cavalier-Smith's model no longer separates prokaryotes and eukaryotes is the statement which differs from kingdom classification.
Explanation:
Cavalier-Smith in 1998 had reduced the kingdom numbers. The were brought down from 8 to 6. These are:
Animalia
Protozoa
fungi
plantae
chromista
bacteria
He divided eukaryotes into 6 kingdoms. The kingdoms are refined for better classification.
While Carolus Linnaeus divided the organisms into two kingdoms
Animalia and plantae.
The five kingdom classification:
Monera (prpkaryotes)
Protista ( unicellular eukaryotes)
fungi (multicellular decomposers)
plantae (multicellular producers)
Animalia (multicellular consumers)
It has drawbacks like in kingdom monera both autotrophs and heterotrophs are included. Phylogeny is not explained in lower organisms of monera and protista. Virus is also in classification. Cavalier-Smith introduced a new kingdom called chromista which are single- celled or multicellular eukaryotic organisms as diatoms, algae, oomycetes and protozoans which perform photosynthesis.
