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.

Which three statements are true about the energy flow in an ecosystem
Lady_Fox [76]

Ecosystem energy flow. Energy's life moves. The energy cycle is based on the flow of energy in an ecosystem through various trophic levels. The cycling energy and nutrients obtained from various external sources maintain our ecosystem.

The responses are A, B, and E. A) Because the sun provides the entire ecosystem with energy, it is a major source of energy. B) because photosynthesis is the process in which plants convert radiant energy from the sun into chemical energy to form sugar-known glucose. E) I believe because, as it moves throughout the ecosystem, the amount of energy at each trophic level decreases.

I hope this helped!!!

One form of chromatin modification is acetylation, which is known to occur on positively charged histone tail amino acids, thus
Naya [18.7K]

Answer:

A. The tails do not interact with the DNA

Explanation:

The acetylation refers to the transfer of the acetyl group from Acetyl-CoA to the N-terminal of the histone protein.

Lysine residues (positively charged amino acid) are present at the end of the N-terminal of the histone protein which is neutralized by the acetyl group.

This loses the compaction between the positively charged histone and the negatively charged DNA and the DNA becomes more relaxed. This relaxed state allows the transcription factors to easily bind the DNA and therefore the DNA becomes transcriptionally active.

Thus, Option-A is correct
