GaryK [48]

Answer:

Yes.

Explanation:

Yes, this change of conditions also change the analysis of the situation because the analysis is related to the environmental conditions. When the environmental condition for an organisms changed so it also change its presence in that environment. If there is plenty of resources such as water, food and space for living, the population of that organism will be higher in that region while on the other hand, if this organisms is moved to a place where the resources such as water, food and space is scarce then it will leads to decrease in population of that organisms so we can say that change in conditions also bring change in our analysis.

Proteins are considered organic molecules because they are made up of carbon atoms. Proteins give your body energy and allows your body to run the way it does. Proteins also aren't considered organic molecules because they are small, because they are not used by living things, or because they contain nitrogen.

Hope this helps.

When an action potential arrives at the axon terminal of a motor neuron, which ion channels open?
HACTEHA [7]

Answer:

Calcium voltage gated ion channels

Explanation:

There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).

The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles  to release acetylcholine via exocytosis into the synaptic cleft.

I hope you find this information useful and interesting! Good luck!
