The correct answer for this question is Acetylcholine receptors at the neuromuscular junction i.e., B
The most basic type of is one in which a single protein or complex of proteins performs both hormone binding and signal generation. Ligand-gated ion channels are included in this category. They consist of two major components: a ligand-binding domain accessible from the cell's surface and a transmembrane domain containing a channel. Binding of ligand to the receptor's exofacial surface causes a conformational change that results in the opening of a pore, allowing specific ions to travel across the plasma membrane through the channel.

The answer would be respiratory. Because asthma affects your breathing which is what the respiratory system is used for. (Lungs)
When a single celled paramedic is placed in a hypotonic solution, the cell swells and then bursts.
<h3><u>
Explanation:</u></h3>
Hypotonic solutions are the solutions that contain more water than present in a cell. Hence, when an animal cell is placed in a hypotonic solution, the cell will undergo osmosis. Osmosis is the movement of any form of solvent through a plasma membrane to a higher concentration from a lower concentration until the the external concentration matches the inner one.
To put it in simple words, when a single animal cell is places in a solution which has more water than other solutes, the water will invade the cell until it can accumulate the amount that equalizes the inner and external concentration. The cell will begin to swell up until there is no more space and finally, it will burst. For example, when you put water on a cloth that has blood stain on it, the cells will burst and make the stain worse than before.
Answer:
Invasion of the large snakes will cause disruptions in this tropical community by increasing competition in tropic level organisms for their food that is primary and secondary consumers.
Explanation:
Invasive species generally and most often harm the native community and may lead to the extinction of native plants and animals from the community. These invasive species increase competition that results in limiting resources and decreasing diversity.
Large snakes will compete with the higher tropic level organism that depends on the primary and secondary level organism that lead to a decrease or extinction of these organisms. This food web will be completely reduced and disrupted, vegetation will increase.
