Primarily, it detects peptidoglycan, which is present in a thick layer in Gram-positive bacteria. ... In Gram-positive bacteria, the cell wall is thick (15-80 nanometers), and consists of several layers of peptidoglycan. They lack the outer membrane envelope found in Gram-negative bacteria.

Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.

All bacteria indicated in the question can be classified by the Gram staining test:

Actinomycetes are Gram-positive bacteria
The genus Arthrobacter includes Gram-positive bacteria
Escherichia coli (E. coli) is a Gram-negative bacterium
Staphylococcus spp. are Gram-positive bacteria
Bacillus spp are Gram-positive bacteria
Mycobacterium spp. are Gram-positive bacteria

Prokaryotes can be divided into two domains: Bacteria and Archaea.

Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.

In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).

Archaebacteria belong to the Archaea domain.

What happens if the correct ligand binds to ligand-gated sodium channel in a post-synaptic neuron?

Maru [420]

Answer:

Post-synaptic neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

Explanation:

Postsynaptic neuron :

These are the neurons that is present after the gap called synapse. These neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

There are number of neurotransmitter. These includes

GABA ergic: This neurotransmitter is often inhibitory.

glutamatergic: This neurotransmitter is often excitatory.

Adrenergic: This neurotransmitter releases norepinephrine.

Cholinergic: This neurotransmitter activates vertebrate neuromuscular junction.
