Active transport into surrounding cells can lead to termination of neurotransmitter activity.
Neurotransmitters are released into the synapses to forward the signals to the receptors of the postsynaptic neurons. These neurotransmitters need to be cleared off to forward new signals. Three mechanisms can be followed to terminate these neurotransmitters in order to introduce new neurotransmitters: diffusion, degradation, and reuptake.
Diffusion
Neurotransmitters in the synapses move until the concentrations are equal. Example- Nitric oxide
Degradation
Neurotransmitters can be broken down by the action of enzymes in order to clear off the synapses. Example- Acetylcholine
Reuptake
Neurotransmitters can also be recycled. In this mechanism, the presynaptic neuron introduces a protein into the synapse that pushes the neurotransmitters against the concentration gradient to push it out of the cell membrane. Examples include glutamate.
Therefore, in the autonomic nervous system, neurotransmitter activation of its receptors terminates when the neurotransmitter is broken down by enzymes, or when it diffuses away, or when it is pushed against the concentration gradient through active transport.

Why could it be dangerous to drink a very large amount of water in a short period of time?
Drinking very large amount of water in a short period of time can result in water intoxication.
Water Intoxication also referred to as water poisoning, is a disruption of brain function brought on by excessive water consumption.
The amount of water in the blood rises as a result. This can dilute the electrolytes, notably sodium, in the blood.
Medics refer to the condition as hyponatremia if sodium levels are less than 135 mmol/l.
The balance of fluids inside and outside of cells is maintained in part by sodium. Increased water intake lowers sodium levels, which causes cells to expand as fluids move from the exterior to the interior of the body.
This can be hazardous and even fatal when it affects brain cells.

Hawaiian silverswords underwent a remarkable adaptive radiation after their ancestor reached Hawaii, while the islands were still young (see Figure 25.22). Would you expect the cattle egret to undergo a similar adaptive radiation in the Americas (see Figure 52.17 )? Explain.
The dispersion of people within a confined area is known as population distribution. People are disproportionately spread out throughout society.
Since it is how invasive species proliferate and how organisms track habitat variations brought on by climate change, the expansion of range is both a crucial applied and fundamental concern.Ecologists claim that a competitor can restrict or even prevent a species' range expansion. The necessity of dispersal is revealed when organisms reach a previously unoccupied area, known as a range extension.As the environment changes, organisms rapidly transform into new forms. Biotic interactions alter or new niches become available when the environment shifts and new resources become available.Hawaiian silverswords, a plant native to North America, is an excellent example of tarweed that spreads widely.

Approximately how long did it take for the frequency of the dominant allele to fall to half its starting value?
It takes approximately 34 months for the frequency of the dominant allele to fall to half its starting value.
When allele frequencies change over time, it's called allele frequency drift. And it turns out that the rate of drift is usually pretty slow: on average, it takes approximately 34 months for the frequency of the dominant allele to fall to half its starting value.
Why does this matter? Well, if you're tracking the frequencies of alleles in a population over time, you need to take drift into account. Otherwise, you might think that the alleles are disappearing when they're actually just drifting to lower frequencies.
So, next time you're looking at allele frequencies, remember to factor in drift! It might not seem like a big deal, but it can definitely make a difference in your interpretation of the data.

An ancestor and all of its descendants are known as a monophyletic group or a clade.
A monophyletic group, or clade, is a group of organisms that includes an ancestor and all of its descendants. This is in contrast to a paraphyletic group, which includes an ancestor and some, but not all, of its descendants.
There are many ways to define monophyly, but one common way is to use phylogenetic trees. A clade is a group of organisms that includes all the descendants of a common ancestor. If two groups are each other's closest relatives, they are said to be monophyletic.
Monophyletic groups tend to be more evolutionarily successful than paraphyletic ones, because they have all the genetic information of their ancestor. This is because they share a common ancestor, and so are more likely to have similar traits.
