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.

Answer:
With the findings of the 2016 Census count on population and dwellings, Statistics Canada gives Canadians a first look at the most recent national statistical snapshot.
The census counts 35,151,728 persons who said they lived in Canada on May 10, 2016, and displays population growth patterns across the country.
The organization will provide the complete spectrum of census data during the following year, as Canadians commemorate 150 years since Confederation, in order to portray a truthful picture of Canadians' lives and communities.
In 1871, the first census following Confederation recorded 3.5 million people in Canada, while the population figure in 2016 was ten times higher. When Canadians celebrated the 100th anniversary of Confederation in 1967, that number had risen to 20.0 million people (1966 Census).
Canadians have been making their way west for many years. The four founding provinces of Ontario, Quebec, New Brunswick, and Nova Scotia housed the majority of Canadians in 1871, whereas Western Canada was lightly populated. Manitoba, Saskatchewan, Alberta, and British Columbia accounted for over a third of the population in 2016.:
There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg.
