Answer:
The addition and response to the net effect of postsynaptic potentials is called Spatial summation
Explanation:
Signal summation occurs when impulses received by a neuron are eummed together to reach the excitation threshold to fire a neuron. It occurs at the axon hillock of a neuron. Signal summation occurs since each neuron is connected to many other neurons, often receiving multiple impulses from them, both excitatory and inhibitory.
Signal summation can either be temporal or spatial.
Temporal summation, occurs when impulses received at the same place on the neuron in close temporal succession add up to initiate an action potential in the neuron.
Spatial summation occurs when impulses received simultaneously at different places on the neuron add up to initiate an action potential in the neuron.
Urine's specific gravity, which is somewhat greater than that of water, is a crucial physical property.
Characteristics of urine:
- Osmolarity is typically harder to quantify than specific gravity, which measures the amount of solutes per volume of a solution. Because there are solutes in urine, its specific gravity is always higher than that of pure water (water = 1.0). Since specific gravity is a less precise predictor of urinary solutes, laboratories may now directly detect the osmolarity of urine.
- Osmolarity, or mOsmol/L, is the measure of how many osmoles or milliosmoles are present in a litre of a fluid. The osmolarity of urine can range from 50 to 100 to 1200 mOsmol/L of water.
Therefore, it is concluded that the correct solution is an option (D), i.e., slightly higher than water.
The complete question is:
An important characteristic of urine is its specific gravity or density, which is ________.
A. the same as water
B. less than water
C. much higher than water
D. slightly higher than water
