Answer;

Nitro.

Explanation:

By far, the most abundant gas in the Earth's atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%.

dusya [7]

The correct answer is neuroplasticity.

Neuroplasticity or brain plasticity is the property of the brain to change. Neuroplasticity can be observed at different levels. For example, changes at the cell level can affect connections between neurons (synaptic plasticity), while non-synaptic plasticity refers to changes in the intrinsic part of the neuron. On the other hand, larger-scale changes are usually made by environmental stimuli. Emotions may cause neuroplastic change through activity-dependent plasticity, which is significant for the recovery from brain damage.

Answer:

plasma membrane of the target cell

Explanation:

There are two main types of acetylcholine (ACh)receptors:

  1. muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
  2. nicotinic ACh receptors (nicotin is agonist) which are  ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).
