Answer:
Colors are assigned to different reflected bands electromegnetic waves.
Explanation:
When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.
So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.
Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.
So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.
Answer:
The correct answer would be -
Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases or goes to zero: rate of ATP synthesis, size of protein gradient
Explanation:
An H+ channel forms and the membrane becomes very permeable to protons if the protein gramicidin is integrated into a membrane. If gramicidin is added to an actively respiring muscle cell, it will affect the in the following manner:
Remains the same:
proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases:
rate of ATP synthesis, size of protein gradient
None of these will show an increase due to the addition of gramicidin tlo actively respiring muscle cells.
It is false that constellations are only visible in certain seasons due to the revolution of the Earth toward the constellation.
Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
