Answer:
Explanation:
Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily. These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.
Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.
Error: Plants are multicellular.
Explanation: Protoctists are known as the dustbin kingdom because they can’t be classified as plants, animals or fungi and they are mostly unicellular microorganisms. Some are known to be more plant-like while others are known to be more animal-like.Euglena is not a plant because it’s a plant-like protoctist.
Answer:
They would instead focus on controlling and diminishing the rodent population.
Explanation:
They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately
