All neurotransmitter receptors should be thought of as having two functions: First, to detect a particular neurotransmitter, and second, to do something<span> when they detect it. The receptor determines what the neurotransmitter's effect is. So it's not always right to call a neurotransmitter inhibitory or excitatory. Glutamate, for example, is among the most common neurotransmitters, and it's almost always excitatory... Except when it binds to a particular type of glutamate receptor, which is inhibitory. Done dopamine receptors are excitatory, some are inhibitory, and not all receptors have effects that fit neatly into those two categories. Sometimes a receptor will have an effect on something completely different... When the NMDA subtype of glutamate receptor is activated, for example, it can cause the postsynaptic cell to change what receptors it puts at that synapse (a cell can have different receptors at different synapses!). Your welcome!

The oxygen-rich surface water blends with the deeper, depleted water. The dissolved oxygen concentration in the mix can be too low to support life in the pond. Both fish and plankton can die from low dissolved oxygen following a turnover. Thus, turnover can happen if a cold rain and wind cools the surface water.

A statistical indication of the link between variables is a correlation. There is a cause-and-effect link between the variables; causality is the idea that changes in one variable create changes in the other. The two variables have a causal relationship as well as a correlation with one another.
What is causal relationship?
If the occurrence of one event results in the other, then there is a causal relationship between the two. The first incident is referred to as the cause, and the second incident as the effect. Two factors may correlate, but that does not prove one caused the other. On the other hand, two variables must be correlated if there is a causal connection between them.
According to a study, there is a link between a student's test-day anxiety and test results that is unfavorable. We cannot, however, conclude that test anxiety is to blame for a student's worse performance because there may be other factors at play, such as poor study habits. In this case, correlation does not prove causality.
