Excitatory postsynaptic potentials (EPSPs) produced nearly simultaneously by different synapses on the same postsynaptic neuron
lakkis [162]

Answer: summation

Explanation:

The process which determine if an action potential will be generated or not depends on the combined effects of the signal inputs from multiple sources of  synapse or from the repeated signals from the same synapse.  

If the input signals reach the threshold voltage, action potential will be generated. (all –or –none principle).Therefore, this  process is a determinant of  the likelihood of action potential generation  and it is called summation.

Summation is the ability to integrate multiple PSPs at multiple synapses.it is  the process that determine if an action potential will be generated by combined effects of inhibitory or excitatory  signals.

Based on the pathways and voulme of applied stimuli in the presynaptic neuron;

The signals can be temporal summation ( consecutive  signals  produced from the same  synapse)where action potential of high frequency in the PSN generated action potential in the post synaptic neuron, which summate with one another. Or Spatial where signals inputs are from multiple presynaptic cells.

What is the wet-bulb depression?
tino4ka555 [31]
The wet bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature. It is measured by a psychrometer . If there is 100% humidity, dry-bulb and wet-bulb temperatures are identical, making the wet-bulb depression equal to zero in such conditions. (In short; the difference between the temperature of a dry bulb and wet bulb.)

Which statements describe the mercalli scale select two options
GenaCL600 [577]

Answer:

hm...

Explanation:

This scale rates an earthquake according to how much damage it causes. This scale produces a single rating for earthquakes that reach the surface. This scale uses Roman numerals to rank the damage caused by an earthquake. This scale measures the magnitude of an earthquake based on the size of seismic waves. ithink all i got the most i cud do gl

What do all living things need?
miss Akunina [59]
They all need energy, food, and water. If we're talking about animals, then they need oxygen. If we're talking about plants, then they need carbon dioxide

They do not need parents. Some animals don't have parents the moment they are born (eg: sea turtles). 

So based on all that, B seems like the best answer

What the seven steps of the water cycle and define each step
Naddik [55]
The first step of the water cycle is evaporation. It is the process where the water at the surface turns into something we call water vapor. The second step is condensation. This is the process when the water vapor turns into ice/water droplets. The third step is sublimation. It is the process of when the ice directly converts into water vapor with out turning into liquid water. The forth step is precipitation. This is when the clouds pour down due to temperature or wind change. The fifth step is <span>transpiration. When the water sinks into the roots of the plant, the transpiration process is similar by when liquid water is turned into water vapor the the plant. The sixth step is runoff. This is when water runs over the surface of the earth. The final process is infiltration. This is if some of the water does not runoff into rivers, the water seeps into the ground and increases the level of ground water table.</span>
