If this neuron depolarizes the presynaptic axon, it allows the signal to be transmitted.
Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.
In an 1H NMR spectrum, the signal for vinyl proton is generally more downfield than an alkyl proton because the additional magnetic field created by the π electrons causes the nearby protons to resonate at a higher frequency.
<h3>What is meant by NMR? </h3>
NMR stands for nuclear magnetic resonance. In this technique, various molecules are studied by studying the interactions of their nucleus with electromagnetic radiations and then recording their radiofrequency.
The nuclei in this case are placed in a strong magnetic field.
This effect was discovered by Zeeman. It is used to study the magnetic properties of nuclei of certain atoms so that they can be appropriately utilized.
Therefore, In a 1H NMR spectrum, the vinyl proton signal is more downfield than an alkyl proton because the additional magnetic field created by the π electrons causes the nearby protons to resonate at a higher frequency.

50/50
you see, the coin only has 2 sides
Also, you're flipping it twice
therefore, the probability is matched up and you have a 50/50 chance of getting heads at least 1 of those 2 times
(Hope it helped ^_^)
The answer is D because if organisms live in a desert biome then these organisms should be used to the hot temperatures, water loss, and strong winds.
