<span>Archaeas and Bacterias are both Prokaryotes. Both used to be classified in Monera kingdom, but later genetists found that they have actually very different genes, despite they both have a similar metabolism. So they think they have a totally different evolutionary origin and they decided to classify them in 2 different domains. The other domain, Eukarya, includes every other organism (all the ones who are not Prokaryots), which are: plants, animals, fungi and protists.</span>
The incorrect statement is: The motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials.
The motor end plate membrane generates threshold potential-"All or None" potential. After the release of acetylcholine from the presynaptic neuron, it diffuses across the neuromuscular junction and binds to its receptors on the muscle fiber. As a result conductance of sodium and potassium is increased which results in depolarization of the muscle cell membrane. This is called a miniature end-plate potential (MEPP) which is additive meaning that it leads to a greater depolarization of the postsynaptic membrane and become end plate potentials (EPPs).
It should be 4. As we can see the relative reactivity of enzymes increase in skins a which has a basic rnvironment. Correct me if I’m wrong please. Thanks
